Comments
This enzyme is composed of large subunits with dinuclear cluster of Mo and Cu along with Molybdopterin cytosine dinucleotide(MCD) as cofactors, small subunits with two iron-sulfur clusters, and medium subunits with FAD as cofactor.
Ni-containing carbon monoxide dehydrogenases and bifunctional enzymes (with acetyl-CoA synthetase) are not homologous, which classified into the identical E.C.
According to the literature [3], this enzyme catalyzes the following reactions:
(A) Oxidation of CO with H2O, yielding CO2, two electrons and two protons (H+) ions:
(B) Electron transfer from CO to S-selanylcysteine 388 (EYS 388 of 1qj2):
(C) Electron transfer from S-selanylcysteine 388 (EYS 388 of 1qj2) to Molybdenum cofactor:
(D) Electron transfer from Molybdenum cofactor to MCD cofactor:
(E) Electron transfer from MCD cofactor to 2Fe-2S cluster-2:
(F) Electron transfer from 2Fe-2S cluster-2 to 2Fe-2S cluster-1:
(G) Electron transfer from 2Fe-2S cluster-1 to flavin group of FAD:
(H) Electron transfer from flavin group of FAD to electron acceptor protein:
