Identification
HMDB Protein ID CDBP00028
Secondary Accession Numbers Not Available
Name Carnitine O-acetyltransferase
Description Not Available
Synonyms
  1. CAT
  2. Carnitine acetylase
  3. Carnitine acetyltransferase
  4. CrAT
Gene Name CRAT
Protein Type Enzyme
Biological Properties
General Function Involved in acyltransferase activity
Specific Function Carnitine acetylase is specific for short chain fatty acids. Carnitine acetylase seems to affect the flux through the pyruvate dehydrogenase complex. It may be involved as well in the transport of acetyl-CoA into mitochondria.
