Related to carnitine acetyltransferase: carnitine palmitoyltransferase

car·ni·tine a·ce·tyl·trans·fer·ase

an enzyme found in mitochondria that catalyzes the reversible transfer of an acetyl group from acetyl-CoA to carnitine, forming O-acetylcarnitine and coenzyme A. Acetylcarnitine is an important fuel source in sperm.


coenzyme of fatty acid oxidation and acetyl transfer; often designated vitamin BT, due to its vitamin role in Tenebrio sp. Present in high concentrations (5% dry weight) in meat extracts.

carnitine acetyltransferase
enzyme associated with buffering of acetyl groups from acetyl CoA.
carnitine deficiency
associated with myocardial disease in dogs, particularly Boxers.

As shown in Table 2, diabetes caused increases in the activities of glucose-o-phosphate dehydrogenase (17%) carnitine acetyltransferase (21%), 2-oxoglutarate dehydrogenase (37%), and fatty acid synthetase (62%), but we found no significant changes in citrate synthase activity (Table 2).
Assay results are critically dependent on two labile reagents, the enzyme carnitine acetyltransferase and the color reagent 5,5'-dithiobis(2-nitrobenzoic acid).
L-Carnitine reacts with acetyl CoA catalyzed by carnitine acetyltransferase (CAT) to form acetyl L-carnitine and CoASH.
