Carbon monoxide dehydrogenase - Wikipedia In enzymology, carbon monoxide dehydrogenase (CODH) (EC 1 2 7 4) is an enzyme that catalyzes the chemical reaction The chemical process catalyzed by carbon monoxide dehydrogenase is similar to the water-gas shift reaction The 3 substrates of this enzyme are CO, H 2 O, and A, whereas its two products are CO 2 and AH 2
Carbon Monoxide Dehydrogenase - an overview - ScienceDirect The resting enzyme is thought to possess a hydroxide molecule bound to the unique Fe in the C-cluster CO binds to the Ni and adopts a bent geometry Nucleophilic attack by the hydroxide on the bound CO carbon forms a Ni–C (O)O–Fe intermediate, which decomposes to release CO 2
Cofactors in Enzymes: Types, Roles, and Mechanisms By binding to specific sites on the enzyme, cofactors can alter the enzyme’s affinity for its substrate, effectively modulating the rate of reaction This modulation can be a means of regulation, allowing cells to fine-tune enzyme activity in response to environmental or metabolic signals
