| - | '''Acetyl-CoA synthetase''' (ACS) catalyzes the ligation of acetate and CoA to form acetyl-CoA with the conversion of ATP to AMP and pyrophosphate. ACS is an ATP-dependent AMP-binding enzyme. Mg+2 is ACS cofactor. ACS participates in the pathway which fixes CO2 under anaerobic conditions. ACS acetylates the response regulator for flagellar movement and for chemotaxis - CheY. | + | '''Acetyl-CoA synthetase''' (ACS) catalyzes the ligation of acetate and CoA to form acetyl-CoA with the conversion of ATP to AMP and pyrophosphate.
