Protein attributes

Sequence length	627 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)

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 By similarity.
Catalytic activity	Acetyl-CoA + carnitine = CoA + O-acetylcarnitine.
Subcellular location	Peroxisome By similarity. Mitochondrion inner membrane; Peripheral membrane protein; Matrix side By similarity.
Sequence similarities	Belongs to the carnitine/choline acetyltransferase family.
