Another iron in the fire: X-ray anomalous diffraction studies on the nitrogenase MoFe protein show the presence of a mononuclear iron site, designated as Fe16, which was previously identified as either Ca(2+) or Mg(2+). The position of the absorption edge indicates that this site is in the oxidation state +2. The high sequence conservation of the residues coordinated to Fe16 emphasizes the potential importance of the site in nitrogenase. ...[more]

Project description:Biosynthesis of nitrogenase P-cluster has attracted considerable attention because it is biologically important and chemically unprecedented. Previous studies suggest that P-cluster is formed from a precursor consisting of paired [4Fe-4S]-like clusters and that P-cluster is assembled stepwise on MoFe protein, i.e., one cluster is assembled before the other. Here, we specifically tackle the assembly of the second P-cluster by combined biochemical and spectroscopic approaches. By using a P-cluster maturation assay that is based on purified components, we show that the maturation of the second P-cluster requires the concerted action of NifZ, Fe protein, and MgATP and that the action of NifZ is required before that of Fe protein/MgATP, suggesting that NifZ may act as a chaperone that facilitates the subsequent action of Fe protein/MgATP. Furthermore, we provide spectroscopic evidence that the [4Fe-4S] cluster-like fragments can be converted to P-clusters, thereby firmly establishing the physiological relevance of the previously identified P-cluster precursor.

Project description:Nitrogenase catalyzes the six electron/six proton reduction of N2 to two ammonia molecules at a complex organometallocluster called "FeMo cofactor." This cofactor is buried within the alpha-subunit of the MoFe protein, with no obvious access for substrates. Examination of high-resolution X-ray crystal structures of MoFe proteins from several organisms has revealed the existence of a water-filled channel that extends from the solvent-exposed surface to a specific face of FeMo cofactor. This channel could provide a pathway for substrate and product access to the active site. In the present work, we examine this possibility by substituting four different amino acids that line the channel with other residues and analyze the impact of these substitutions on substrate reduction kinetic parameters. Each of the MoFe protein variants was purified and kinetic parameters were established for the reduction of the substrates N2, acetylene, azide, and propyne. For each MoFe protein, V (max) values for the different substrates were found to be nearly unchanged when compared with the values for the wild-type MoFe protein, indicating that electron delivery to the active site is not compromised by the various substitutions. In contrast, the K(m) values for these substrates were found to increase significantly (up to 22-fold) in some of the MoFe protein variants compared with the wild-type MoFe protein values. Given that each of the amino acids that were substituted is remote from the active site, these results are consistent with the water-filled channel functioning as a substrate channel in the MoFe protein.

Project description:The engineering of transgenic organisms with the ability to fix nitrogen is an attractive possibility. However, oxygen sensitivity of nitrogenase, mainly conferred by the reductase component (NifH)2 , is an imminent problem. Nitrogenase-like enzymes involved in coenzyme F430 and chlorophyll biosynthesis utilize the highly homologous reductases (CfbC)2 and (ChlL)2 , respectively. Chimeric protein-protein interactions of these reductases with the catalytic component of nitrogenase (MoFe protein) did not support nitrogenase activity. Nucleotide-dependent association and dissociation of these complexes was investigated, but (CfbC)2 and wild-type (ChlL)2 showed no modulation of the binding affinity. By contrast, the interaction between the (ChlL)2 mutant Y127S and the MoFe protein was markedly increased in the presence of ATP (or ATP analogues) and reduced in the ADP state. Upon formation of the octameric (ChlL)2 MoFe(ChlL)2 complex, the ATPase activity of this variant is triggered, as seen in the homologous nitrogenase system. Thus, the described reductase(s) might be an attractive tool for further elucidation of the diverse functions of (NifH)2 and the rational design of a more robust reductase.

Project description:The X-ray crystal structure of the nitrogenase MoFe protein from Clostridium pasteurianum (Cp1) has been determined at 1.08 Å resolution by multiwavelength anomalous diffraction phasing. Cp1 and the ortholog from Azotobacter vinelandii (Av1) represent two distinct families of nitrogenases, differing primarily by a long insertion in the α-subunit and a deletion in the β-subunit of Cp1 relative to Av1. Comparison of these two MoFe protein structures at atomic resolution reveals conserved structural arrangements that are significant to the function of nitrogenase. The FeMo cofactors defining the active sites of the MoFe protein are essentially identical between the two proteins. The surrounding environment is also highly conserved, suggesting that this structural arrangement is crucial for nitrogen reduction. The P clusters are likewise similar, although the surrounding protein and solvent environment is less conserved relative to that of the FeMo cofactor. The P cluster and FeMo cofactor in Av1 and Cp1 are connected through a conserved water tunnel surrounded by similar secondary-structure elements. The long α-subunit insertion loop occludes the presumed Fe protein docking surface on Cp1 with few contacts to the remainder of the protein. This makes it plausible that this loop is repositioned to open up the Fe protein docking surface for complex formation.

Project description:Proton uptake accompanies the reduction of all known substrates by nitrogenase. As a consequence, a higher pH should limit the availability of protons as a substrate essential for turnover, thereby increasing the proportion of more highly reduced forms of the enzyme for further study. The utility of the high-pH approach would appear to be problematic in view of the observation reported by Pham and Burgess [(1993) Biochemistry 32, 13725-13731] that the MoFe-protein undergoes irreversible protein denaturation above pH 8.65. In contrast, we found by both enzyme activity and crystallographic analyses that the MoFe-protein is stable when incubated at pH 9.5. We did observe, however, that at higher pHs and under turnover conditions, the MoFe-protein is slowly inactivated. While a normal, albeit low, level of substrate reduction occurs under these conditions, the MoFe-protein undergoes a complex transformation; initially, the enzyme is reversibly inhibited for substrate reduction at pH 9.5, yet in a second, slower process, the MoFe-protein becomes irreversibly inactivated as measured by substrate reduction activity at the optimal pH of 7.8. The final inactivated MoFe-protein has an increased hydrodynamic radius compared to that of the native MoFe-protein, yet it has a full complement of iron and molybdenum. Significantly, the modified MoFe-protein retains the ability to specifically interact with its nitrogenase partner, the Fe-protein, as judged by the support of ATP hydrolysis and by formation of a tight complex with the Fe-protein in the presence of ATP and aluminum fluoride. The turnover-dependent inactivation coupled to conformational change suggests a mechanism-based transformation that may provide a new probe of nitrogenase catalysis.

Project description:A molybdenum L-edge X-ray absorption spectroscopy (XAS) study is presented for native and oxidized MoFe protein of nitrogenase as well as Mo-Fe model compounds. Recently collected data on MoFe protein (in oxidized and reduced forms) is compared to previously published Mo XAS data on the isolated FeMo cofactor in NMF solution and put in context of the recent Mo K-edge XAS study, which showed a MoIII assignment for the molybdenum atom in FeMoco. The L3-edge data are interpreted within a simple ligand-field model, from which a time-dependent density functional theory (TDDFT) approach is proposed as a way to provide further insights into the analysis of the molybdenum L3-edges. The calculated results reproduce well the relative spectral trends that are observed experimentally. Ultimately, these results give further support for the MoIII assignment in protein-bound FeMoco, as well as isolated FeMoco.

Project description:We demonstrate electrochemical control of the nitrogenase MoFe protein, in the absence of Fe protein or ATP, using europium(iii/ii) polyaminocarboxylate complexes as electron transfer mediators. This allows the potential dependence of proton reduction and inhibitor (CO) binding to the active site FeMo-cofactor to be established. Reduction of protons to H2 is catalyzed by the wild type MoFe protein and ?-98Tyr?His and ?-99Phe?His variants of the MoFe protein at potentials more negative than -800 mV (vs. SHE), with greater electrocatalytic proton reduction rates observed for the variants compared to the wild type protein. Electrocatalytic proton reduction is strongly attenuated by carbon monoxide (CO), and the potential-dependence of CO binding to the FeMo-cofactor is determined by in situ infrared (IR) spectroelectrochemistry. The vibrational wavenumbers for CO coordinated to the FeMo-cofactor are consistent with earlier IR studies on the MoFe protein with Fe protein/ATP as reductant showing that electrochemically generated states of the protein are closely related to states generated with the native Fe protein as electron donor.

Project description:MgADP- reacted with the nitrogenase molybdenum-iron (MoFe) protein of Klebsiella pneumoniae (Kp1) over a period of 2 h to yield a stable, catalytically active conjugate. The isolated protein exhibited a new, broad 31P NMR resonance at -1 p.p.m. lacking phosphorus J coupling. The adenine ring of [8-14C]ADP remained associated with the conjugate. A covalently bound nucleotide was identified as AMP by NMR and TLC. Extended dialysis of Kp1 against MgADP- resulted in further AMP binding at the protein surface. ADP was initially bound tightly to Kp1 at a site distinct from the AMP sites. ATP did not replace ADP. The time course of the formation of the Kp1-AMP was altered by the nitrogenase iron protein (Kp2) and was dependent on redox potential. Kp1-AMP was stable to concentration and oxidation with ferricyanide ion at -350 mV. Slow hydrolysis of Kp1-AMP over a period of 6 h yielded AMP and unaltered Kp1. The adenine ring of ADP exchanged with adenine of MgATP2- during reductant-limited turnover of nitrogenase under N2, indicating reversibility of ATP hydrolysis at 15 degrees C. [32P]Pi exchanged with the terminal phosphate group of both ADP and ATP on incubation with Kp1. 32P exchange and the catalytic activity of Kp1 were inhibited by a 20-fold molar excess of the lysine-modifying reagent, o-phthalaldehyde (OPT). Preincubation with MgADP- protected against OPT inactivation. Two potentially reactive lysine residues on the alpha chain of the MoFe protein near a putative hydrophobic docking site for the nitrogenase Fe protein are proposed as sites of OPT and nucleotide binding. Azotobacter vinelandii MoFe protein (Av1) also formed an AMP adduct but Kp2 did not. Catalase did not interact with ADP. The reactions of the nitrogenase MoFe protein with adenine nucleotides have no counterpart in known protein-nucleotide interactions.

Project description:In the nitrogenase molybdenum-iron (MoFe) protein, we have identified five potential substrate access pathways from the protein surface to the FeMo-cofactor (the active site) or the P-cluster using experimental structures of Xe pressurized into MoFe protein crystals from Azotobacter vinelandii and Clostridium pasteurianum. Additionally, all published structures of the MoFe protein, including those from Klebsiella pneumoniae, were analyzed for the presence of nonwater, small molecules bound to the protein interior. Each pathway is based on identification of plausible routes from buried small molecule binding sites to both the protein surface and a metallocluster. Of these five pathways, two have been previously suggested as substrate access pathways. While the small molecule binding sites are not conserved among the three species of MoFe protein, residues lining the pathways are generally conserved, indicating that the proposed pathways may be accessible in all three species. These observations imply that there is unlikely a unique pathway utilized for substrate access from the protein surface to the active site; however, there may be preferred pathways such as those described here.

Project description:Our previous investigation of substrates reduction catalyzed by nitrogenase suggested that ?-Ile423 of MoFe protein possibly functions as an electron transfer gate to Mo site of active center-"FeMoco". Amino acid residue ?-Lys424 connects directly to ?-Ile423, and they are located in the same ?-helix (?423-431). In the present study, function of ?-Lys424 was investigated by replacing it with Arg (alkaline, like Lys), Gln (neutral), Glu (acidic), and Ala (neutral) through site-directed mutagenesis and homologous recombination. The mutants were, respectively, termed 424R, 424Q, 424E, and 424A. Studies of diazotrophic cell growth, cytological, and enzymatic properties indicated that none of the substitutions altered the secondary structure of MoFe protein, or normal expression of nifA, nifL, and nifD. Substitution of alkaline amino acid (i.e., 424R) maintained acetylene (C2H2) and proton (H+) reduction activities at normal levels similar to that of wild-type (WT), because its FeMoco content did not reduce. In contrast, substitution of acidic or neutral amino acid (i.e., 424Q, 424E, 424A) impaired the catalytic activity of nitrogenase to varying degrees. Combination of MoFe protein structural simulation and the results of a series of experiments, the function of ?-Lys424 in ensuring insertion of FeMoco to MoFe protein was further confirmed, and the contribution of ?-Lys424 in maintaining low potential of the microenvironment causing efficient catalytic activity of nitrogenase was demonstrated.
