[https://www.uniprot.org/uniprot/A0A3B6UEQ0_9ENTR A0A3B6UEQ0_9ENTR] This is one of three E.coli hydrogenases synthesized in response to different physiological conditions. 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. | |||
