Subcellular location

Subcellular Location:
Peroxisome

Function

Function:
Beta-oxidation of fatty acids. The highest activity concerns the C6 to C10 chain length substrate. Converts the end product of pristanic acid beta oxidation, 4,8-dimethylnonanoyl-CoA, to its corresponding carnitine ester.
Pathway:
Lipid metabolism; fatty acid beta-oxidation.
Catalytic Activity:
Octanoyl-CoA + L-carnitine = CoA + L-octanoylcarnitine.
Active Site:
ACT_SITE 327 327 Proton acceptor.
