Protein

Iron hydrogenase 1

Gene
N/A
Organism
Clostridium pasteurianum
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalytic activityi

H2 + 2 oxidized ferredoxin = 2 reduced ferredoxin + 2 H+.

Cofactori

Protein has several cofactor binding sites:
  • [2Fe-2S] clusterNote: Binds 1 [2Fe-2S] cluster per subunit.
  • [4Fe-4S] clusterNote: Binds 4 [4Fe-4S] clusters per subunit.
  • Fe cationNote: Binds 2 iron ions per subunit. Besides cysteine ligand the diiron subcluster contains non-protein ligands including 2 sulfur atoms, 1 water and 5 cyanide or carbon monoxide ligands.
