General annotation (Comments)

Function	Activation of long-chain fatty acids for both synthesis of cellular lipids, and degradation via beta-oxidation. Preferentially uses myristate, laurate, arachidonate and eicosapentaenoate as substrates By similarity.
Catalytic activity	ATP + a long-chain carboxylic acid + CoA = AMP + diphosphate + an acyl-CoA.
Cofactor	Magnesium By similarity.
Subcellular location	Mitochondrion outer membrane; Single-pass type III membrane proteinBy similarity. Peroxisome membrane; Single-pass type III membrane proteinBy similarity. Microsome membrane; Single-pass type III membrane proteinBy similarity. Endoplasmic reticulum membrane; Single-pass type III membrane proteinBy similarity.
Sequence similarities	Belongs to the ATP-dependent AMP-binding enzyme family.
