Carnitine O-octanoyltransferase

In enzymology, a carnitine O-octanoyltransferase is an enzyme that catalyzes the chemical reaction


 * octanoyl-CoA + L-carnitine $$\rightleftharpoons$$ CoA + L-octanoylcarnitine

Thus, the two substrates of this enzyme are octanoyl-CoA and L-carnitine, whereas its two products are CoA and L-octanoylcarnitine.

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 octanoyl-CoA:L-carnitine O-octanoyltransferase. Other names in common use include medium-chain/long-chain carnitine acyltransferase, carnitine medium-chain acyltransferase, easily solubilized mitochondrial carnitine palmitoyltransferase, and overt mitochondrial carnitine palmitoyltransferase.
