CO dehydrogenase enzyme

Reductive acetyl-CoA pathway 4-5 3 NAD(P)H, 2-3 ferredoxin, 1 H2 (in methanogens) Acetyl-CoA synthase/ CO dehydrogenase, formate dehydrogenase, pyruvate synthase C02 Acetyl-CoA, pyruvate Acetyl-CoA synthase/CO dehydrogenase, enzymes reducing C02 to methyltetrahydropterin... 

CO dehydrogenase enzymes catalyze two organometallic reactions. The first one resembles the water-gas-shift reaction (see Chap. 20) except that 2 and 2 e are produced instead of H2 ...
