Thus, the two substrates of this enzyme are 4,8,12-trimethyltridecanoyl-CoA and propanoyl-CoA, whereas its two products are 3-oxopristanoyl-CoA and CoA.
This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is 4,8,12-trimethyltridecanoyl-CoA:propanoyl-CoA C2-4,8,12-trimethyltridecanoyltransferase. Other names in common use include 3-oxopristanoyl-CoA hydrolase, 3-oxopristanoyl-CoA thiolase, peroxisome sterol carrier protein thiolase, sterol carrier protein, oxopristanoyl-CoA thiolase, peroxisomal 3-oxoacyl coenzyme A thiolase, SCPx, 4,8,12-trimethyltridecanoyl-CoA:propanoyl-CoA, and 2-C-4,8,12-trimethyltridecanoyltransferase.
