Ligand-dependent interdomain rearrangements drive catalysis by acetyl-CoA synthetases.
Acetyl-coenzyme A synthetases convert ATP, acetate, and coenzyme A (CoA) into acetyl-CoA, a central metabolite that fuels lipid biosynthesis and regulates protein and RNA acetylation. ACS enzymes contain N- and C-terminal domains that coordinate a two-step ping-pong mechanism involving sequential adenylation and thioes...
