This study investigates the N2-fixing system of Methanocaldococcus infernus, revealing structural insights into its thermostable nitrogenase and unifying mechanistic principles across nitrogenase types.

This paper elucidates how anaerobes regulate nitrogenase activity through the PII-protein couple NifI1 and NifI2, revealing a structural mechanism for energy-dependent N2-fixation control.

The paper demonstrates that carbon monoxide-driven ethanol production in Clostridium autoethanogenum uses a tungsten-dependent aldehyde:ferredoxin oxidoreductase, with ferredoxin facilitating electron transfer and enzyme activity.

The paper determines atomic structures of MCRs from anaerobic methanotrophic archaea, revealing conserved structures and post-translational modifications.

The paper identifies and characterizes mini-bacterioferritin, a novel ferritin-like protein from an anaerobic methane-oxidizing archaeon, revealing its structure and evolutionary relationships.

The paper presents structural snapshots of the CODH/ACS complex in CO2 fixation, revealing conformational changes and reaction mechanisms for acetyl-CoA synthesis.

This study identifies F420 reduction as a key driver in anaerobic ethanotrophy by characterizing archaeal enzymes and their structural interactions with F420-reductase modules.
