Carnitine O-palmitoyltransférase

Carnitine O-palmitoyltransférase

La carnitine O-palmitoyltransférase (CPT) est une enzyme mitochondriale de type transférase (EC 2.3.1.21), impliquée dans le métabolisme de la palmitoylcarnitine en palmitoyl-CoA.

Une enzyme transférase proche est la carnitine acyltransférase.
