Purification and structural characterization of the Na+-translocating ferredoxin: NAD+ reductase (Rnf) complex of Clostridium tetanomorphum

Autor: Stella Vitt, Simone Prinz, Martin Eisinger, Ulrich Ermler, Wolfgang Buckel

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-11 (2022)

Rnf reversibly reduces NAD+ by ferredoxin coupled with Na+/H+ pumping for microbial ion gradient or reduced ferredoxin formation. Here, a cryo-EM structure provides information about the participating iron and flavin cofactors, the electron transfer

Energy Conservation in Fermentations of Anaerobic Bacteria

Autor: Wolfgang Buckel

Publikováno v: Frontiers in Microbiology, Vol 12 (2021)

Anaerobic bacteria ferment carbohydrates and amino acids to obtain energy for growth. Due to the absence of oxygen and other inorganic electron acceptors, the substrate of a fermentation has to serve as electron donor as well as acceptor, which resul

Formation of 3‐hydroxyglutaric acid in glutaric aciduria type I: in vitro participation of medium chain acyl‐CoA dehydrogenase

Autor: Verena Peters, Marina Morath, Matthias Mack, Michael Liesert, Wolfgang Buckel, Georg F. Hoffmann, Jerry Vockley, Sandro Ghisla, Johannes Zschocke

Publikováno v: JIMD Reports, Vol 47, Iss 1, Pp 30-34 (2019)

Abstract 3‐Hydroxyglutaric acid (3‐OH‐GA) in urine has been identified as the most reliable diagnostic marker for glutaric aciduria type I (GA I). We showed that hydratation of glutaconyl‐CoA to 3‐hydroxyglutaryl‐CoA, which is subsequentl

Molecular and Low-Resolution Structural Characterization of the Na+-Translocating Glutaconyl-CoA Decarboxylase From Clostridium symbiosum

Autor: Stella Vitt, Simone Prinz, Nils Hellwig, Nina Morgner, Ulrich Ermler, Wolfgang Buckel

Publikováno v: Frontiers in Microbiology, Vol 11 (2020)

Some anaerobic bacteria use biotin-dependent Na+-translocating decarboxylases (Bdc) of β-keto acids or their thioester analogs as key enzymes in their energy metabolism. Glutaconyl-CoA decarboxylase (Gcd), a member of this protein family, drives the

The semiquinone swing in the bifurcating electron transferring flavoprotein/butyryl-CoA dehydrogenase complex from Clostridium difficile

Autor: Julius K. Demmer, Nilanjan Pal Chowdhury, Thorsten Selmer, Ulrich Ermler, Wolfgang Buckel

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-10 (2017)

The electron-transferring flavoprotein / butyryl-CoA dehydrogenase (EtfAB/Bcd) complex catalyzes the reduction of crotonyl-CoA and ferredoxins by NADH in anaerobic microbes. Here, the authors present the crystal structure of Clostridium difficile Etf

Flavin-Based Electron Bifurcation, Ferredoxin, Flavodoxin, and Anaerobic Respiration With Protons (Ech) or NAD+ (Rnf) as Electron Acceptors: A Historical Review

Autor: Wolfgang Buckel, Rudolf K. Thauer

Publikováno v: Frontiers in Microbiology, Vol 9 (2018)

Flavin-based electron bifurcation is a newly discovered mechanism, by which a hydride electron pair from NAD(P)H, coenzyme F420H2, H2, or formate is split by flavoproteins into one-electron with a more negative reduction potential and one with a more
