Dual role of HupF in the biosynthesis of [NiFe] hydrogenase
BMC Microbiology, 2012 Background [NiFe] hydrogenases are enzymes that catalyze the oxidation of hydrogen into protons and electrons, to use H2 as energy source, or the production of hydrogen through proton reduction, as an escape valve for the excess of reduction equivalents ...

Angewandte Chemie, EarlyView.Two‐dimensional (2D) infrared (IR) spectroscopy provides vastly more structural and functional insight into chemical and biological systems than linear IR spectroscopy. Here, we apply 2D‐IR spectroscopy to two controversially discussed states of the [FeFe] hydrogenase active site, revealing the presence of a bridging carbonyl ligand, which is difficult

Tyrosine, cysteine, and S-adenosyl methionine stimulate in vitro [FeFe] hydrogenase activation. [PDF]
PLoS ONE, 2009 BACKGROUND:[FeFe] hydrogenases are metalloenzymes involved in the anaerobic metabolism of H(2). These proteins are distinguished by an active site cofactor known as the H-cluster.

Recent advances in electron transfer between biofilms and metals [PDF]
, 2007 Microbial biofilms produce electrochemical interactions with metal surfaces by following a wide variety of different electron exchange pathways. Reviewing the mechanisms identified in the biocorrosion of steels leads us to distinguish direct and indirect

Frontiers in Catalysis, 2022 Hydrogenase-mediated reduction of flavin mononucleotide by H2 is exploited to enable cleaner application of nitroreductase enzymes for reduction of aromatic nitro functional groups. This turns the overall reaction into a biocatalytic hydrogenation.

Optimization of carbon and energy utilization through differential translational efficiency. [PDF]
, 2018 Control of translation is vital to all species. Here we employ a multi-omics approach to decipher condition-dependent translational regulation in the model acetogen Clostridium ljungdahlii.

Proceedings of the National Academy of Sciences, 1977 Previous reports of a relatively air-stable soluble hydrogenase from the photosynthetic anaerobe, Chromatium vinosum, have been substantiated. The properties of this enzyme, as seen in highly purified samples prepared by procedures that permit improved yields, are described. A possible role for flavin mediation is noted.

On the pathways feeding the H₂ production process in nutrient-replete, hypoxic conditions : commentary on the article 'Low oxygen levels contribute to improve photohydrogen production in mixotrophic non-stressed Chlamydomonas cultures', by Jurado-Oller et al., Biotechnology for Biofuels, published September 7, 2015; 8:149 [PDF]
, 2017 Background: Under low O-2 concentration ( hypoxia) and low light, Chlamydomonas cells can produce H-2 gas in nutrient-replete conditions. This process is hindered by the presence of O-2, which inactivates the [FeFe]-hydrogenase enzyme responsible for H-2

BMC Microbiology, 2009 Background The last step in the maturation process of the large subunit of [NiFe]-hydrogenases is a proteolytic cleavage of the C-terminal by a hydrogenase specific protease.
