Protein attributes

Sequence length	577 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Has medium-chain fatty acid:CoA ligase activity with broad substrate specificity (in vitro). Acts on acids from C4 to C11 and on the corresponding 3-hydroxy- and 2,3- or 3,4-unsaturated acids (in vitro) By similarity.
Catalytic activity	ATP + a carboxylate + CoA = AMP + diphosphate + an acyl-CoA.
Cofactor	Magnesium or manganese.
Subunit structure	Monomer By similarity.
Subcellular location	Mitochondrion matrix By similarity.
Sequence similarities	Belongs to the ATP-dependent AMP-binding enzyme family.
Sequence caution	The sequence AAC23497.1 differs from that shown. Reason: Erroneous gene model prediction.
