, 2020 The catalytic mechanism of H2 conversion by [NiFe]-hydrogenase is subject of extensive research. Apart from at least four reaction intermediates of H2/H+ cycling, there is also a number of resting states, which are formed under oxidizing conditions ...

Microbial Electrosynthesis Reshapes Energy Metabolism and Physiology in Clostridium ljungdahlii
Microbial Biotechnology, Volume 19, Issue 6, June 2026.Microbial electrosynthesis drives Clostridium ljungdahlii into a distinct stress‐associated physiological state, different from gas fermentation. Comparative multi‐omics and electron microscopy reveal physiological constraints that help explain the poor performance of MES.

Synthesis and kinetics study of diiron-hydrogenase active site mimics
, 2012 The hydrogenase enzyme is an effective replacement for the expensive platinum catalysts used in hydrogen fuel cells today. However, many enzymes themselves are found in extreme environments and are inactive under standard conditions, but current active ...

Glutamate Gated Proton-Coupled Electron Transfer Activity of a [NiFe]-Hydrogenase
, 2016 [NiFe] hydrogenases are metalloenzymes that catalyze the reversible oxidation of H2. While electron transfer to and from the active site is understood to occur through iron–sulfur clusters, the mechanism of proton transfer is still debated.

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.Evaluation the effects of potentially toxic co‐contaminating metal cations, including cadmium (Cd), lead (Pb), and Zinc (Zn), on the bioreduction of selenite by a consortium of halotolerant and halophilic bacteria and/or yeast. ABSTRACT Selenium oxyanion pollution in the environment, often originating from anthropogenic industrial activities, causes ...

Frontiers in Microbiology, 2019 The active site of all [NiFe]-hydrogenases (Hyd) has a bimetallic NiFe(CN)2CO cofactor that requires the combined action of several maturation proteins for its biosynthesis and insertion into the precursor form of the large subunit of the enzyme ...

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.Protein sequence surveys show that nickel‐ and molybdenum/copper‐containing carbon monoxide dehydrogenases (CODHs) are widespread in the ocean. Phylogenetic and genome context analyses reveal that marine CODHs are highly diverse in both evolutionary history and functional organisation.

Role of Nickel in Microbial Pathogenesis
Inorganics, 2019 Nickel is an essential cofactor for some pathogen virulence factors. Due to its low availability in hosts, pathogens must efficiently transport the metal and then balance its ready intracellular availability for enzyme maturation with metal toxicity ...

The Plant Journal, Volume 126, Issue 5, June 2026.Significance Statement Life on Earth depends on photosynthetic CO2 fixation via the Calvin–Benson–Bassham cycle to form organic carbon. This process evolved first in cyanobacteria and was later conveyed to eukaryotes, giving rise to plastids in algae and plants. To cope with low atmospheric CO2 concentrations that developed over the course of evolution,
