comments
This enzyme catalyzes the following reactions:
(A) Electron transfer from heme iron of cytochrome c3 to [4Fe-4S] cluster-2 located on the surface of small subunit:
(A1) His184 (1frf) bound to Fe4-S4, is exposed to the surface of the S subunit. This residue might interact with cytochrome c3, for electron transfer (see [12]).
(B) Electron transfer from [4Fe-4S] cluster-2 to [3Fe-4S] cluster:
(B1) Indirect transfer from [4Fe-4S] cluster-2 to [3Fe-4S] cluster through Cys218 (bound to [4Fe-4S] cluster-2) and Cys245 (bound to [3Fe-4S]) (see [12]).
(C) Electron transfer from [3Fe-4S] cluster to [4Fe-4S] cluster-1:
(C1) Indirect transfer from [3Fe-4S] cluster to [4Fe-4S] cluster-1 through Cys248 (bound to [3Fe-4S]) and Cys147 (bound to [4Fe-4S] cluster-1) (see [12]).
(D) Electron transfer from [4Fe-4S] cluster-1 to the Nickel-Iron cluster (reaction center):
(D1) Indirect transfer from [4Fe-4S] cluster-1 to Nickel-Iron cluster through Cys17 (bound to [4Fe-4S] cluster-1) and Cys72 of Large subunit (bound to Nickel-Iron cluster) (see [12]).
(E) Hydrogenation at the Nickel-Iron cluster (reaction center):
