GO Classification
Functions
  • carnitine O-acetyltransferase activity
  • receptor binding
Processes
  • carnitine metabolic process, CoA-linked
  • transport
  • small molecule metabolic process
  • cellular lipid metabolic process
  • fatty acid beta-oxidation using acyl-CoA oxidase
Components
  • mitochondrion
  • endoplasmic reticulum
  • mitochondrial inner membrane
  • peroxisome
  • peroxisomal matrix
General FunctionReceptor binding
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.
