Identification
NameCarnitine O-acetyltransferase, mitochondrial
Synonyms
  • Carnitine acetylase
Gene NameCAT2
Enzyme Class
Biological Properties
General FunctionInvolved in acyltransferase activity
Specific FunctionCarnitine 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
Cellular LocationPeroxisome. Mitochondrion inner membrane; Peripheral membrane protein; Matrix side
