Plant based production of myoglobin - a novel source of the muscle heme-protein.

ABSTRACT: Myoglobin is a heme-protein in the muscle of vertebrates with important functions in the oxygenation of tissues and as a regulator in nitric oxide signaling. Myoglobin from many species is also an important nutritional source of bioavailable iron. In this study, we have successfully produced human myoglobin in the leaves of Nicotiana benthamiana by transient expression using a viral vector delivered by Agrobacterium tumefaciens. Analyses confirmed that heme was incorporated and the protein was functional, with observed properties consistent with those of native myoglobins. A relatively high degree of purity could be achieved with low cost methods. The results show the high potential of plants as a production platform for heme proteins, a group of proteins of interest for iron nutrition applications and possible future pharmaceutical development.

Platforms for Plant-Based Protein Production

Project description:Plant molecular farming depends on a diversity of plant systems for production of useful recombinant proteins. These proteins include protein biopolymers, industrial proteins and enzymes, and therapeutic proteins. Plant production systems include microalgae, cells, hairy roots, moss, and whole plants with both stable and transient expression. Production processes involve a narrowing diversity of bioreactors for cell, hairy root, microalgae, and moss cultivation. For whole plants, both field and automated greenhouse cultivation methods are used with products expressed and produced either in leaves or seeds. Many successful expression systems now exist for a variety of different products with a list of increasingly successful commercialized products. This chapter provides an overview and examples of the current state of plant-based production systems for different types of recombinant proteins.

Fe-heme conformations in ferric myoglobin.

Project description:X-ray absorption near-edge structure (XANES) spectra of ferric myoglobin from horse heart have been acquired as a function of pH (between 5.3 and 11.3). At pH = 11.3 temperature-dependent spectra (between 20 and 293 K) have been collected as well. Experimental data solve three main conformations of the Fe-heme: the first, at low pH, is related to high-spin aquomet-myoglobin (Mb+OH2). The other two, at pH 11.3, are related to hydroxymet-myoglobin (Mb+OH-), and are in thermal equilibrium, corresponding to high- and low-spin Mb+OH-. The structure of the three Fe-heme conformations has been assigned according to spin-resolved multiple scattering simulations and fitting of the XANES data. The chemical transition between Mb+OH2 and high-spin Mb+OH-, and the spin transition of Mb+OH-, are accompanied by changes of the Fe coordination sphere due to its movement toward the heme plane, coupled to an increase of the axial asymmetry.

Insights Into How Heme Reduction Potentials Modulate Enzymatic Activities of a Myoglobin-based Functional Oxidase.

Project description:Heme-copper oxidase (HCO) is a class of respiratory enzymes that use a heme-copper center to catalyze O2 reduction to H2 O. While heme reduction potential (E°') of different HCO types has been found to vary >500?mV, its impact on HCO activity remains poorly understood. Here, we use a set of myoglobin-based functional HCO models to investigate the mechanism by which heme E°' modulates oxidase activity. Rapid stopped-flow kinetic measurements show that increasing heme E°' by ca. 210?mV results in increases in electron transfer (ET) rates by 30-fold, rate of O2 binding by 12-fold, O2 dissociation by 35-fold, while decreasing O2 affinity by 3-fold. Theoretical calculations reveal that E°' modulation has significant implications on electronic charge of both heme iron and O2 , resulting in increased O2 dissociation and reduced O2 affinity at high E°' values. Overall, this work suggests that fine-tuning E°' in HCOs and other heme enzymes can modulate their substrate affinity, ET rate and enzymatic activity.

Analysis of Fluctuation in the Heme-Binding Pocket and Heme Distortion in Hemoglobin and Myoglobin.

Project description:Heme is located in the active site of proteins and has diverse and important biological functions, such as electron transfer and oxygen transport and/or storage. The distortion of heme porphyrin is considered an important factor for the diverse functions of heme because it correlates with the physical properties of heme, such as oxygen affinity and redox potential. Therefore, clarification of the relationship between heme distortion and the protein environment is crucial in protein science. Here, we analyzed the fluctuation in heme distortion in the protein environment for hemoglobin and myoglobin using molecular dynamics (MD) simulations and quantum mechanical (QM) calculations as well as statistical analysis of the protein structures of hemoglobin and myoglobin stored in Protein Data Bank. Our computation and statistical analysis showed that the protein environment for hemoglobin and myoglobin prominently affects the doming distortion of heme porphyrin, which correlates with its oxygen affinity, and that the magnitude of distortion is different between hemoglobin and myoglobin. These results suggest that heme distortion is affected by its protein environment and fluctuates around its fitted conformation, leading to physical properties that are appropriate for protein functions.

Rational Design of Dual Active Sites in a Single Protein Scaffold: A Case Study of Heme Protein in Myoglobin.

Project description:Rational protein design has been proven to be a powerful tool for creating functional artificial proteins. Although many artificial metalloproteins with a single active site have been successfully created, those with dual active sites in a single protein scaffold are still relatively rare. In this study, we rationally designed dual active sites in a single heme protein scaffold, myoglobin (Mb), by retaining the native heme site and creating a copper-binding site remotely through a single mutation of Arg118 to His or Met. Isothermal titration calorimetry (ITC) and electron paramagnetic resonance (EPR) studies confirmed that a copper-binding site of [3-His] or [2-His-1-Met] motif was successfully created in the single mutant of R118H Mb and R118M Mb, respectively. UV/Vis kinetic spectroscopy and EPR studies further revealed that both the heme site and the designed copper site exhibited nitrite reductase activity. This study presents a new example for rational protein design with multiple active sites in a single protein scaffold, which also lays the groundwork for further investigation of the structure and function relationship of heme/non-heme proteins.

Role of heme in the unfolding and assembly of myoglobin.

Project description:The unfolding of wild-type holomyoglobin in the ferric state (metMb) appears to be a simple two-state process, even though hemichrome spectra are often observed and apoMb denaturation involves an intermediate. To resolve these discrepancies, we measured GuHCl-induced, equilibrium unfolding of five sperm whale metMb variants, which were selected to examine the relative importance of apoglobin stability and hemin affinity. Combined analysis of CD, Trp fluorescence, and Soret absorbance titration curves for all the variants requires a six-state mechanism containing native (N), intermediate (I), and unfolded (U) states of apoMb and their hemin-bound counterparts, NH (holoMb), IH, and UH, respectively. The unfolding parameters for the apoMbs were obtained in independent experiments and then fixed in the analysis of the holoprotein data, where only the affinities of the apoglobin states for hemin were allowed to vary. This cofactor binding analysis applies generally to all globins and led to three specific conclusions. (1) The stability of holo-metMb is determined primarily by the high affinity (K(d) approximately 10(-13) M) of native apoMb (N) for hemin. (2) The partially unfolded intermediate with hemin bound (IH) has a hemichrome spectrum indicative of a bis-histidyl axial coordination and is seen clearly when the stability of the N state or its affinity for hemin is reduced. (3) Although the affinity of the intermediate for hemin (K(d) approximately 10(-11) M) is approximately 100-fold lower than that for the native state, free hemin can bind to it and promote the assembly of the holoprotein.

The novel heme-dependent inducible protein, SRRD regulates heme biosynthesis and circadian rhythms

Project description:In order to investigate the function of heme in the regulation of gene expression, we herein examined variations in mRNA levels in ALA-treated cells from control conditions. A comprehensive anal- ysis by RNA sequencing showed marked changes in the expression of various genes. Among the different amounts of mRNA, we identified the novel heme-inducible protein, SRRD. The plant ho- mologue Sensitivity to Red Light Reduced (SRR1) was previously reported to be involved in the regulation of the circadian clock and phytochrome B signaling in Arabidopsis thaliana. We found that SRRD regulated not only heme biosynthesis, but also the expression of clock genes. The involvement of SRRD in the prolif- eration of cells was also demonstrated.

Investigations of ferric heme cyanide photodissociation in myoglobin and horseradish peroxidase.

Project description:The photodissociation of cyanide from ferric myoglobin (MbCN) and horseradish peroxidase (HRPCN) has definitively been observed. This has implications for the interpretation of ultrafast IR (Helbing et al. Biophys. J. 2004, 87, 1881-1891) and optical (Gruia et al. Biophys. J. 2008, 94, 2252-2268) studies that had previously suggested the Fe-CN bond was photostable in MbCN. The photolysis of ferric MbCN takes place with a quantum yield of ~75%, and the resonance Raman spectrum of the photoproduct observed in steady-state experiments as a function of laser power and sample spinning rate is identical to that of ferric Mb (metMb). The data are quantitatively analyzed using a simple model where cyanide is photodissociated and, although geminate rebinding with a rate of kBA ? (3.6 ps)(-1) is the dominant process, some CN(-) exits from the distal heme pocket and is replaced by water. Using independently determined values for the CN(-) association rate, we find that the CN(-) escape rate from the ferric myoglobin pocket to the solution at 293 K is kout ? (1-2) × 10(7) s(-1). This value is very similar to, but slightly larger than, the histidine gated escape rate of CO from Mb (1.1 × 10(7) s(-1)) under the same conditions. The analysis leads to an escape probability kout/(kout + kBA) ~ 10(-4), which is unobservable in most time domain kinetic measurements. However, the photolysis is surprisingly easy to detect in Mb using cw resonance Raman measurements. This is due to the anomalously slow CN(-) bimolecular association rate (170 M(-1) s(-1)), which arises from the need for water to exchange at the ferric heme binding site of Mb. In contrast, ferric HRP does not have a heme bound water molecule and its CN(-) bimolecular association rate is larger by ~10(3), making the CN(-) photolysis more difficult to observe.

An engineered heme-copper center in myoglobin: CO migration and binding.

Project description:We have investigated CO migration and binding in CuBMb, a copper-binding myoglobin double mutant (L29H-F43H), by using Fourier transform infrared spectroscopy and flash photolysis over a wide temperature range. This mutant was originally engineered with the aim to mimic the catalytic site of heme-copper oxidases. Comparison of the wild-type protein Mb and CuBMb shows that the copper ion in the distal pocket gives rise to significant effects on ligand binding to the heme iron. In Mb and copper-free CuBMb, primary and secondary ligand docking sites are accessible upon photodissociation. In copper-bound CuBMb, ligands do not migrate to secondary docking sites but rather coordinate to the copper ion. Ligands entering the heme pocket from the outside normally would not be captured efficiently by the tight distal pocket housing the two additional large imidazole rings. Binding at the Cu ion, however, ensures efficient trapping in CuBMb. The Cu ion also restricts the motions of the His64 side chain, which is the entry/exit door for ligand movement into the active site, and this restriction results in enhanced geminate and slow bimolecular CO rebinding. These results support current mechanistic views of ligand binding in hemoglobins and the role of the CuB in the active of heme-copper oxidases. This article is part of a Special Issue entitled: Oxygen Binding and Sensing Proteins.

GAPDH is involved in the heme-maturation of myoglobin and hemoglobin.

Project description:GAPDH, a heme chaperone, has been previously implicated in the incorporation of heme into iNOS and soluble guanylyl cyclase (sGC). Since sGC is critical for myoglobin (Mb) heme-maturation, we investigated the role of GAPDH in the maturation of this globin, as well as hemoglobins α, β, and γ. Utilizing cell culture systems, we found that overexpression of wild-type GAPDH increased, whereas GAPDH mutants H53A and K227A decreased, the heme content of Mb and Hbα and Hbβ. Overexpression of wild-type GAPDH fully recovered the heme-maturation inhibition observed with the GAPDH mutants. Partial rescue was observed by overexpression of sGCβ1 but not by overexpression of a sGCΔβ1 deletion mutant, which is unable to bind the sGCα1 subunit required to form the active sGCα1β1 complex. Wild type and mutant GAPDH was found to be associated in a complex with each of the globins and Hsp90. GAPDH at endogenous levels was found to be associated with Mb in differentiating C2C12 myoblasts, and with Hbγ or Hbα in differentiating HiDEP-1 erythroid progenitor cells. Knockdown of GAPDH in C2C12 cells suppressed Mb heme-maturation. GAPDH knockdown in K562 erythroleukemia cells suppressed Hbα and Hbγ heme-maturation as well as Hb dimerization. Globin heme incorporation was not only dependent on elevated sGCα1β1 heterodimer formation, but also influenced by iron provision and magnitude of expression of GAPDH, d-aminolevulinic acid, and FLVCR1b. Together, our data support an important role for GAPDH in the maturation of myoglobin and γ, β, and α hemoglobins.
