Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 3.13Å Ligands: EDO, FAD, FE, FES, GOL, MES, NFU, PE4, SO4 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Publication Abstract from PubMed Hydrogenases catalyze reversible H(2) production and are potential models for renewable energy catalysts. Here, the full redox landscape of a group 3 [NiFe]-hydrogenase from methanothermococcus thermolithotrophicus is elucidated, resembling group 1 enzymes. Structural and spectroscopic analyses reveal a catalytic-ready state with nickel seesaw coordination, enabling intermediate trapping and advancing mechanistic understanding of oxygen-sensitive [NiFe] enzymes.
