ACSM1, BUCS1, LAE, MACS1, Acyl-coenzyme A synthetase ACSM1, mitochondrial, Acyl-CoA synthetase medium-chain family member 1, Butyrate--CoA ligase 1, Butyryl-coenzyme A synthetase 1, Lipoate-activating enzyme, Middle-chain acyl-CoA synthetase 1

ACSM1 has medium-chain fatty acid:CoA ligase activity with broad substrate specificity (in vitro). This protein acts on acids from C(4) to C(11) and on the corresponding 3-hydroxy-and 2,3-or 3,4-unsaturated acids (in vitro). This protein functions as GTP-dependent lipoate-activating enzyme that generates the substrate for lipoyltransferase
