Involved in the maturation of [NiFe] hydrogenases. Along with HypE, it catalyzes the synthesis of the CN ligands of the active site iron of [NiFe]-hydrogenases. HypF 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. ATP + C-terminal L-cysteinyl-[HypE protein] + carbamoyl phosphate + H2O = AMP + C-terminal S-carboxamide-L-cysteinyl-[HypE protein] + diphosphate + H(+) + phosphate Protein modification; [NiFe] hydrogenase maturation. Belongs to the carbamoyltransferase HypF family.
