Structural highlights

Function

HYPF_ECOLI Along with HypE, it catalyzes the synthesis of the CN ligands of the active site iron of [NiFe]-hydrogenases using carbamoylphosphate as a substrate. It functions as a carbamoyl transferase using carbamoylphosphate as a substrate and transferring the carboxamido moiety in an ATP-dependent reaction to the thiolate of the C-terminal cysteine of HypE yielding a protein-S-carboxamide.^{[1] [2] [3] [4]}
