General annotation (Comments)

Function

Catalyzes the desaturation of acyl-CoAs to 2-trans-enoyl-CoAs. Isoform 1 shows highest activity against medium-chain fatty acyl-CoAs and activity decreases with increasing chain length. Isoform 2 is active against a much broader range of substrates and shows activity towards very long-chain acyl-CoAs. Isoform 1 shows optimum activity with a chain length of 10 carbons while isoform 2 exhibits optimum activity with 14 carbons. Ref.4

Catalytic activity

Acyl-CoA + O2 = trans-2,3-dehydroacyl-CoA + H2O2.

Cofactor

FAD.

Pathway

Lipid metabolism; peroxisomal fatty acid beta-oxidation.

Subunit structure

Homodimer. The enzyme contains three components A, B and C, the latter two being produced from the first by a proteolytic cleavage. Ref.5 Ref.6

Subcellular location

Peroxisome.

Sequence similarities

Belongs to the acyl-CoA oxidase family.
