Predicted to enable acetoacetate-CoA ligase activity and butyrate-CoA ligase activity. Predicted to be involved in several processes, including cellular response to glucose stimulus; positive regulation of insulin secretion; and response to oleic acid. Predicted to act upstream of or within fatty acid metabolic process. Predicted to be located in cytoplasm. Predicted to be active in cytosol. Is expressed in alimentary system; eye; hemolymphoid system; nervous system; and urinary system. Orthologous to human AACS (acetoacetyl-CoA synthetase).
