Function
ACS1_YEAST Catalyzes the production of acetyl-CoA. Provides the acetyl-CoA source for histone acetylation in the nucleus. "Aerobic" isozyme of acetyl-coenzyme A synthetase, which supports growth on nonfermentable carbon sources such as glycerol and ethanol. May be required for assimilation of ethanol and acetate.[1] [2]

Publication Abstract from PubMed
Acetyl-coenzyme A synthetase (ACS) belongs to the family of AMP-forming enzymes that also includes acyl-CoA synthetases, firefly luciferase, and nonribosomal peptide synthetases. ACS catalyzes the two-step activation of acetate to acetyl-CoA: formation of an acetyl-AMP intermediate from acetate and ATP and the transfer of the acetyl group to CoA. In mammals, the acetyl-CoA product is used for biosynthesis of long chain fatty acids as well as energy production. We have determined the crystal structure of yeast ACS in a binary complex with AMP at 2.3 A resolution. The structure contains a large, N-terminal domain and a small, C-terminal domain. AMP is bound at the interface between the two domains. This structure represents a new conformation for the ACS enzyme, which may be competent for catalyzing the first step of the reaction. A Lys residue that is critical for this step is located in the active site. A rotation of 140 degrees in the small domain is needed for the binding of CoA and the catalysis of the second step. In contrast to the monomeric bacterial enzyme, yeast ACS is a stable trimer.
