Thus, the two substrates of this enzyme are acyl-CoA and O2, whereas its two products are trans-2,3-dehydroacyl-CoA and H2O2.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with oxygen as acceptor. The systematic name of this enzyme class is acyl-CoA:oxygen 2-oxidoreductase. Other names in common use include fatty acyl-CoA oxidase, acyl coenzyme A oxidase, and fatty acyl-coenzyme A oxidase. This enzyme participates in 3 metabolic pathways: fatty acid metabolism, polyunsaturated fatty acid biosynthesis, and ppar signaling pathway. It employs one cofactor, FAD.
Structural studies
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1IS2, 1W07, 2DDH, 2FON, 2IX5, and 2IX6.
