Binding interactions of porphyrin derivatives with Ca(2+) ATPase of sarcoplasmic reticulum (SERCA1a).

ABSTRACT: The use of Porphyrin derivatives as photosensitizers in Photodynamic Therapy (PDT) was investigated by means of a molecular docking study. These molecules can bind to intracellular targets such as P-type CaCa(2+) ATPase of sarcoplasmic reticulum (SERCA1a). CAChe software was successfully employed for conducting the docking of Tetraphenylporphinesulfonate(TPPS), 5,10,15,20- Tetrakis (4-sulfonatophenyl) porphyrinato Iron(III) Chloride (FeTPPS) and 5,10,15,20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron(III) nitrosyl Chloride (FeNOTPPS) with CaCa(2+) ATPase from sarcoplasmic reticulum of rabbit. The results show that FeNOTPPS forms the most stable complex with CaCa(2+) ATPase.

Mitsugumin 53 attenuates the activity of sarcoplasmic reticulum Ca(2+)-ATPase 1a (SERCA1a) in skeletal muscle.

Project description:Mitsugumin 53 (MG53) is a member of the membrane repair system in skeletal muscle. However, the roles of MG53 in the unique functions of skeletal muscle have not been addressed, although it is known that MG53 is expressed only in skeletal and cardiac muscle. In the present study, MG53-binding proteins were examined along with proteins that mediate skeletal muscle contraction and relaxation using the binding assays of various MG53 domains and quadrupole time-of-flight mass spectrometry. MG53 binds to sarcoplasmic reticulum Ca(2+)-ATPase 1a (SERCA1a) via its tripartite motif (TRIM) and PRY domains. The binding was confirmed in rabbit skeletal muscle and mouse primary skeletal myotubes by co-immunoprecipitation and immunocytochemistry. MG53 knockdown in mouse primary skeletal myotubes increased Ca(2+)-uptake through SERCA1a (more than 35%) at micromolar Ca(2+) but not at nanomolar Ca(2+), suggesting that MG53 attenuates SERCA1a activity possibly during skeletal muscle contraction or relaxation but not during the resting state of skeletal muscle. Therefore MG53 could be a new candidate for the diagnosis and treatment of patients with Brody syndrome, which is not related to the mutations in the gene coding for SERCA1a, but still accompanies exercise-induced muscle stiffness and delayed muscle relaxation due to a reduction in SERCA1a activity.

Calcium binding and allosteric signaling mechanisms for the sarcoplasmic reticulum Ca²+ ATPase.

Project description:The sarcoplasmic reticulum Ca²? ATPase (SERCA) is a membrane-bound pump that utilizes ATP to drive calcium ions from the myocyte cytosol against the higher calcium concentration in the sarcoplasmic reticulum. Conformational transitions associated with Ca²?-binding are important to its catalytic function. We have identified collective motions that partition SERCA crystallographic structures into multiple catalytically-distinct states using principal component analysis. Using Brownian dynamics simulations, we demonstrate the important contribution of surface-exposed, polar residues in the diffusional encounter of Ca²?. Molecular dynamics simulations indicate the role of Glu309 gating in binding Ca²?, as well as subsequent changes in the dynamics of SERCA's cytosolic domains. Together these data provide structural and dynamical insights into a multistep process involving Ca²? binding and catalytic transitions.

Critical roles of interdomain interactions for modulatory ATP binding to sarcoplasmic reticulum Ca2+-ATPase.

Project description:ATP has dual roles in the reaction cycle of sarcoplasmic reticulum Ca(2+)-ATPase. Upon binding to the Ca2E1 state, ATP phosphorylates the enzyme, and by binding to other conformational states in a non-phosphorylating modulatory mode ATP stimulates the dephosphorylation and other partial reaction steps of the cycle, thereby ensuring a high rate of Ca(2+) transport under physiological conditions. The present study elucidates the mechanism underlying the modulatory effect on dephosphorylation. In the intermediate states of dephosphorylation the A-domain residues Ser(186) and Asp(203) interact with Glu(439) (N-domain) and Arg(678) (P-domain), respectively. Single mutations to these residues abolish the stimulation of dephosphorylation by ATP. The double mutation swapping Asp(203) and Arg(678) rescues ATP stimulation, whereas this is not the case for the double mutation swapping Ser(186) and Glu(439). By taking advantage of the ability of wild type and mutant Ca(2+)-ATPases to form stable complexes with aluminum fluoride (E2·AlF) and beryllium fluoride (E2·BeF) as analogs of the E2·P phosphoryl transition state and E2P ground state, respectively, of the dephosphorylation reaction, the mutational effects on ATP binding to these intermediates are demonstrated. In the wild type Ca(2+)-ATPase, the ATP affinity of the E2·P phosphoryl transition state is higher than that of the E2P ground state, thus explaining the stimulation of dephosphorylation by nucleotide-induced transition state stabilization. We find that the Asp(203)-Arg(678) and Ser(186)-Glu(439) interdomain bonds are critical, because they tighten the interaction with ATP in the E2·P phosphoryl transition state. Moreover, ATP binding and the Ser(186)-Glu(439) bond are mutually exclusive in the E2P ground state.

Functional properties of a sarcoplasmic reticulum Ca(2+)-ATPase with an altered Ca(2+)-binding mechanism.

Project description:Treatment of sarcoplasmic reticulum vesicles with diethylpyrocarbonate in the presence of a large excess of reagent, at pH 6.2 and at room temperature, reveals both a fast- and a slow-reacting population of protein residues. The loss of the Ca(2+)-ATPase activity is mainly associated with the fast-reacting population being partially sensitive to hydroxylamine. There is also an effect on the Ca(2+)-binding mechanism. Shorter derivatization times (5 min) produce a loss of the positive cooperativity of Ca2+ binding. When the treatment was prolonged for 30 min there was an additional decrease in the overall Ca2+ affinity. Curve-fitting procedures applied to the non-cooperative binding isotherms provide the equilibrium constants for the two Ca2+ sites, although they cannot discriminate between interacting and independent site mechanisms. Prestationary kinetics assays show 2 Ca2+:1 ATP ratios, at any extent of Ca2+ saturation, indicating that the Ca2+ sites are not independent. The Ca2+ dissociation profile after derivatization shows a decrease in the dissociation constant for the release of the second Ca2+, which is consistent with interacting sites. Isotopic exchange experiments show fast and slow components of equal amplitude even at subsaturating Ca2+ concentrations, which is incompatible with independent binding sites. The experimental data suggest a modification of the equilibrium binding constants making them more similar, but keeping the interacting character. The structural position of the external (cytoplasmic) and the internal (lumenal) Ca2+ sites remains unaltered in the absence of positive cooperativity.

Cysteine-674 oxidation and degradation of sarcoplasmic reticulum Ca(2+) ATPase in diabetic pig aorta.

Project description:The sarcoplasmic reticulum Ca2+ ATPase (SERCA) is redox-regulated by posttranslational thiol modifications of cysteine-674 to regulate smooth muscle relaxation and migration. To detect oxidation of cysteine-674 that irreversibly prevents redox regulation, a polyclonal, sequence-specific antibody was developed toward a peptide containing cysteine-674 sulfonic acid. The antibody stained intact 110-kDa SERCA in pig cardiac SR that was oxidized in vitro by peroxynitrite in a sequence-specific manner, and histochemically stained atherosclerotic pig and rabbit aorta. Surprisingly, immunoblots of the pig aorta failed to stain intact 110-kDa SERCA protein, but rather, higher molecular mass aggregates and lower molecular mass bands. Of the latter bands at 70 and 60 kDa, the largest were observed in diabetic, hyperlipidemic pigs, and coincided with the most positive histochemical staining. The 70- and 60-kDa molecular mass bands also coincided with the majority of the protein detected by a monoclonal total anti-SERCA antibody, which detected the intact 110-kDa protein in normal pigs. Mass spectrometry identified SERCA in all the major bands detected by the sulfonic acid antibody as well as the oxidation of cysteine-674 in the 70-kDa band. These studies demonstrate a sequence-specific antibody that detects partial degradation products of SERCA, which represent the majority of the protein in some diabetic hypercholesterolemic pig aortae. In addition, the results suggest an association between irreversible oxidation of SERCA and its degradation, and that an important portion of the oxidized protein in tissue samples may be partially degraded.

Binding of Ca2+ to the (Ca(2+)-Mg2+)-ATPase of sarcoplasmic reticulum: equilibrium studies.

Project description:Equilibrium fluorescence methods have been used to establish a model for Ca2+ binding to the (Ca(2+)-Mg2+)-ATPase of skeletal muscle sarcoplasmic reticulum and to define the effects of H+ and Mg2+ on Ca2+ binding. The basic scheme proposed is: E2 <--> E1 <--> E1Ca <--> El'Ca <--> E1'Ca2. The E1 conformation of the ATPase initially has one high-affinity binding site for Ca2+ exposed to the cytoplasmic side of the sarcoplasmic reticulum, but in the E2 conformation this site is unable to bind Ca2+; Ca2+ does not bind to luminal sites on E2. The second, outer, Ca(2+)-binding site on the ATPase is formed after binding of Ca2+ to the first, inner, site on E1 and the E1Ca <--> E1'Ca conformation change. The pH- and Mg(2+)-dependence of the E2 <--> E1 equilibrium has been established after changes in the fluorescence of the ATPase labelled with 4-nitrobenzo-2-oxa-1,3-diazole. It is proposed that Mg2+ from the cytoplasmic side of the sarcoplasmic reticulum can bind to the first Ca(2+)-binding site on both E1 and E2. It is proposed that the change in tryptophan fluorescence intensity after binding of Ca2+ follows from the E1Ca <--> E1'Ca change. The pH- and Mg(2+)-dependence of this change defines H(+)- and Mg(2+)-binding constants at the two Ca(2+)-binding sites. It is proposed that the change in tryptophan fluorescence observed on binding Mg2+ follows from binding at the second Ca(2+)-binding site. Effects of pH and Mg2+ on the fluorescence of the ATPase labelled with 4-(bromomethyl)-6,7-dimethoxycoumarin are proposed to follow from binding to a site on the ATPase, the 'gating' site, which affects the affinity of the first Ca(2+)-binding site for Ca2+ and affects the rate of dissociation of Ca2+ from the ATPase.

Binding of Ca2+ to the (Ca(2+)-Mg2+)-ATPase of sarcoplasmic reticulum: kinetic studies.

Project description:Stop-flow fluorescence and rapid-filtration methods have been used to establish the kinetics of Ca2+ binding to, and dissociation from, the (Ca(2+)-Mg2+)-ATPase of skeletal-muscle sarcoplasmic reticulum and to define the effects of H+ and Mg2+ on Ca2+ binding and dissociation rates. The kinetics have been interpreted in terms of the scheme: E2 E2<==>E1<==>E1Ca<==>E1'Ca<==>E1'Ca2. The kinetics of the E2<==>E1 E1 transition have been determined by measuring the rate of change of the fluorescence of the ATPase labelled with 4-nitrobenzo-2-oxa-1,3-diazole after a pH jump or the addition of Ca2+ to the labelled ATPase in the presence of thapsigargin or thapsivillosin A. It has been shown that Mg2+ has a marked effect on Ca2+ dissociation at pH 7.2 and that changes in the tryptophan fluorescence of the ATPase follow the same time course as the dissociation of 45Ca2+. It is proposed that the effect of Mg2+ follows from binding to a 'gating' site, as detected by changes in the fluorescence of the ATPase labelled with 4-(bromomethyl)-6,7-dimethoxycoumarin. The rate of dissociation of Ca2+ from the ATPase increases with increasing pH. The rate of dissociation of Ca2+ decreases with increasing Ca2+ concentration in the medium, with an apparent affinity for Ca2+ greater than that seen for the change in fluorescence amplitude. It is shown that this follows if the first, inner, Ca(2+)-binding site on the ATPase has a lower affinity for Ca2+ than the second, outer, site. Effects of H+ and Mg2+ on Ca2+ dissociation can be treated by the quasiequilibrium approach. Mg2+ and H+ also affect the rate of Ca2+ binding to the ATPase, and effects of H+ and Mg2+ on the E2<==>E1 equilibrium explain the results of experiments in which the concentrations of H+ and Mg2+ are jumped.

Ion pathways in the sarcoplasmic reticulum Ca2+-ATPase.

Project description:The sarco/endoplasmic reticulum Ca(2+)-ATPase (SERCA) is a transmembrane ion transporter belonging to the P(II)-type ATPase family. It performs the vital task of re-sequestering cytoplasmic Ca(2+) to the sarco/endoplasmic reticulum store, thereby also terminating Ca(2+)-induced signaling such as in muscle contraction. This minireview focuses on the transport pathways of Ca(2+) and H(+) ions across the lipid bilayer through SERCA. The ion-binding sites of SERCA are accessible from either the cytoplasm or the sarco/endoplasmic reticulum lumen, and the Ca(2+) entry and exit channels are both formed mainly by rearrangements of four N-terminal transmembrane ?-helices. Recent improvements in the resolution of the crystal structures of rabbit SERCA1a have revealed a hydrated pathway in the C-terminal transmembrane region leading from the ion-binding sites to the cytosol. A comparison of different SERCA conformations reveals that this C-terminal pathway is exclusive to Ca(2+)-free E2 states, suggesting that it may play a functional role in proton release from the ion-binding sites. This is in agreement with molecular dynamics simulations and mutational studies and is in striking analogy to a similar pathway recently described for the related sodium pump. We therefore suggest a model for the ion exchange mechanism in P(II)-ATPases including not one, but two cytoplasmic pathways working in concert.

Normal mode-based fitting of atomic structure into electron density maps: application to sarcoplasmic reticulum Ca-ATPase.

Project description:A method for the flexible docking of high-resolution atomic structures into lower resolution densities derived from electron microscopy is presented. The atomic structure is deformed by an iterative process using combinations of normal modes to obtain the best fit of the electron microscopical density. The quality of the computed structures has been evaluated by several techniques borrowed from crystallography. Two atomic structures of the SERCA1 Ca-ATPase corresponding to different conformations were used as a starting point to fit the electron density corresponding to a different conformation. The fitted models have been compared to published models obtained by rigid domain docking, and their relation to the known crystallographic structures are explored by normal mode analysis. We find that only a few number of modes contribute significantly to the transition. The associated motions involve almost exclusively rotation and translation of the cytoplasmic domains as well as displacement of cytoplasmic loops. We suggest that the movements of the cytoplasmic domains are driven by the conformational change that occurs between nonphosphorylated and phosphorylated intermediate, the latter being mimicked by the presence of vanadate at the phosphorylation site in the electron microscopy structure.

Structural basis for sarcolipin's regulation of muscle thermogenesis by the sarcoplasmic reticulum Ca<sup>2+</sup>-ATPase.

Project description:The sarcoplasmic reticulum (SR) Ca2+-ATPase (SERCA) plays a central role in muscle contractility and nonshivering thermogenesis. SERCA is regulated by sarcolipin (SLN), a single-pass membrane protein that uncouples Ca2+ transport from ATP hydrolysis, promoting futile enzymatic cycles and heat generation. The molecular determinants for regulating heat release by the SERCA/SLN complex are unclear. Using thermocalorimetry, chemical cross-linking, and solid-state NMR spectroscopy in oriented phospholipid bicelles, we show that SERCA’s functional uncoupling and heat release rate are dictated by specific SERCA/SLN intramembrane interactions, with the carboxyl-terminal residues anchoring SLN to the SR membrane in an inhibitory topology. Systematic deletion of the carboxyl terminus does not prevent the SERCA/SLN complex formation but reduces uncoupling in a graded manner. These studies emphasize the critical role of lipids in defining the active topology of SLN and modulating the heat release rate by the SERCA/SLN complex, with implications in fat metabolism and basal metabolic rate.
