HYD2 is involved in hydrogen uptake.[ARBA:ARBA00059419] Publication Abstract from PubMed Citrobacter sp. S-77 [NiFe]-hydrogenase harbors a standard [4Fe-4S] cluster proximal to the Ni-Fe active site. The presence of relocatable water molecules and a flexible aspartate enables the [4Fe-4S] to display redox-dependent conformational changes. These structural features are proposed to be the key aspects that protect the active site from O2 attack. Redox-dependent conformational changes of a proximal [4Fe-4S] cluster in Hyb-type [NiFe]-hydrogenase to protect the active site from O2.,Noor NDM, Matsuura H, Nishikawa K, Tai H, Hirota S, Kim J, Kang J, Tateno M, Yoon KS, Ogo S, Kubota S, Shomura Y, Higuchi Y Chem Commun (Camb). 2018 Oct 30;54(87):12385-12388. doi: 10.1039/c8cc06261g.
