EC 2.3.1.21     
Accepted name: carnitine O-palmitoyltransferase
Reaction: palmitoyl-CoA + L-carnitine = CoA + L-palmitoylcarnitine
Other name(s): CPT; CPTo; outer malonyl-CoA inhibitable carnitine palmitoyltransferase; CPTi; CPT I (outer membrane carnitine palmitoyl transferase); carnitine palmitoyltransferase I; carnitine palmitoyltransferase II; CPT-A; CPT-B; acylcarnitine transferase; carnitine palmitoyltransferase; carnitine palmitoyltransferase-A; L-carnitine palmitoyltransferase; palmitoylcarnitine transferase
Systematic name: palmitoyl-CoA:L-carnitine O-palmitoyltransferase
Comments: Broad specificity to acyl group, over the range C8 to C18; optimal activity with palmitoyl-CoA. cf. EC 2.3.1.7 carnitine O-acetyltransferase and EC 2.3.1.137 carnitine O-octanoyltransferase.
