Acetyl-CoA synthase
From Proteopedia
Acetyl-CoA synthase (ACS) is a Fe-Ni-S containing enzyme found in archae and bacteria. ACS is divided to 4 classes. ACS-I catalyzes the synthesis of acetyl-CoA from CoA, CO2, methyl group and 2 electrons. ACS-II catalyzes the reverse reaction. ACS-III uses pyruvate as the source of CO2 and 2 electrons to produce acetyl-CoA. ACS-IV catabolizes CO to CO2. ACS-I and ACS-II contain 5 subunits: α, β, γ, δ, ε. ACS-III is composed of 2 proteins: 2α+2β and γ+δ. ACS-IV is composed of α monomer. ACS can form a bifunctional entity with carbon monoxide dehydrogenase (CODH).
