Electron Transfer to Nitrogenase in Different Genomic and Metabolic Backgrounds

Journal Article Poudel, Saroj ; Colman, Daniel R. ; Fixen, Kathryn R. ; ... - Journal of Bacteriology

Nitrogenase catalyzes the reduction of dinitrogen (N₂) using low-potential electrons from ferredoxin (Fd) or flavodoxin (Fld) through an ATP-dependent process. Since its emergence in an anaerobic chemoautotroph, this oxygen (O₂)-sensitive enzyme complex has evolved to operate in a variety of genomic and metabolic backgrounds, including those of aerobes, anaerobes, chemotrophs, and phototrophs. However, whether pathways of electron delivery to nitrogenase are influenced by these different metabolic backgrounds is not well understood. Here, we report the distribution of homologs of Fds, Flds, and Fd-/Fld-reducing enzymes in 359 genomes of putative N₂ fixers (diazotrophs). Six distinct lineages of nitrogenase were identified, andmore »« less

Influence of Energy and Electron Availability on In Vivo Methane and Hydrogen Production by a Variant Molybdenum Nitrogenase

Journal Article Zheng, Yanning ; Harwood, Caroline S. ; Müller, Volker - Applied and Environmental Microbiology

ABSTRACT The anoxygenic phototrophic bacteriumRhodopseudomonas palustrisproduces methane (CH₄) from carbon dioxide (CO₂) and hydrogen (H₂) from protons (H⁺) when it expresses a variant form of molybdenum (Mo) nitrogenase that has two amino acid substitutions near its active site. We examined the influence of light energy and electron availability onin vivoproduction of these biofuels. Nitrogenase activity requires large amounts of ATP, and cells exposed to increasing light intensities produced increasing amounts of CH₄and H₂. As expected for a phototroph, intracellular ATP increased with increasing light intensity, but there was only a loose correlation between ATP content and CH₄and H₂production. There wasmore »« less

Negative cooperativity in the nitrogenase Fe protein electron delivery cycle

Journal Article Danyal, Karamatullah ; Shaw, Sudipta ; Page, Taylor R. ; ... - Proceedings of the National Academy of Sciences of the United States of America

Mo-dependent nitrogenase catalyzes the biological reduction of atmospheric dinitrogen (N₂) to two ammonia (NH₃) molecules, through the action of two component proteins, the MoFe protein and the Fe protein. The catalytic MoFe protein is a symmetric dimer of αβ units, each of which contains one active site FeMo-co (FeMo-co; [7Fe-9S-Mo-C-homocitrate]) and an electron-carrier P cluster. Each half of the nitrogenase ternary complex, in which one Fe protein with two bound ATP molecules has bound to each MoFe protein αβ unit, undergoes an electron transfer (ET) cycle with ET from a Fe protein [4Fe-4S] cluster into its αβ unit followed bymore »« less

The Electron Bifurcating FixABCX Protein Complex from Azotobacter vinelandii: Generation of Low-Potential Reducing Equivalents for Nitrogenase Catalysis

Journal Article Ledbetter, Rhesa N. ; Garcia Costas, Amaya M. ; Lubner, Carolyn E. ; ... - Biochemistry

The biological reduction of dinitrogen (N₂) to ammonia (NH₃) by nitrogenase is an energetically demanding reaction that requires low-potential electrons and ATP; however, pathways used to deliver the electrons from central metabolism to the reductants of nitrogenase, ferredoxin or flavodoxin, remain unknown for many diazotrophic microbes. The FixABCX protein complex has been proposed to reduce flavodoxin or ferredoxin using NADH as the electron donor in a process known as electron bifurcation. Herein, the FixABCX complex from Azotobacter vinelandii was purified and demonstrated to catalyze an electron bifurcation reaction: oxidation of NADH (E_m = -320 mV) coupled to reduction of flavodoxinmore »« less
