Carnitine palmitoyltransferase I

Carnitine bound in the catalytic site of CRAT, an enzyme homologous to CPT1. The catalytic histidine and stabilizing serine residues are colored orange.
Carnitine palmitoyltransferase mechanism.
Acyl-CoA from cytosol to the mitochondrial matrix

Carnitine palmitoyltransferase I (CPT1) also known as carnitine acyltransferase I, CPTI, CAT1, CoA:carnitine acyl transferase (CCAT), or palmitoylCoA transferase I, is a mitochondrial enzyme responsible for the formation of acyl carnitines by catalyzing the transfer of the acyl group of a long-chain fatty acyl-CoA from coenzyme A to l-carnitine. The product is often Palmitoylcarnitine (thus the name), but other fatty acids may also be substrates. It is part of a family of enzymes called carnitine acyltransferases. This "preparation" allows for subsequent movement of the acyl carnitine from the cytosol into the intermembrane space of mitochondria.
