2i6r is a 4 chain structure with sequence from Escherichia coli O157:H7. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
HYPE_ECOLI Involved in the maturation of [NiFe] hydrogenases. Along with HypF, it catalyzes the synthesis of the CN ligands of the active site iron of [NiFe]-hydrogenases. HypE catalyzes the ATP-dependent dehydration of the carboxamido group attached to its C-terminal cysteine to a cyano group (PubMed:12586941, PubMed:15291820). The cyano group is then transferred from HypE to the HypC-HypD complex or the HybG-HypD complex (PubMed:15504408).[1][2][3]
