Presumably involved in regulating the intracellular acetyl-CoA pool for fatty acid and cholesterol synthesis and fatty acid oxidation. It may be involved in overall regulation of acetylation during melatonin synthesis. acetyl-CoA + H2O = acetate + CoA + H(+) Monomer. Glycosylated; contains mannose. Present with 4890 molecules/cell in log phase SD medium. Belongs to the acetyl-CoA hydrolase/transferase family.
