• Function: Catalyzes the transfer of the acyl group of long-chain fatty acid-CoA conjugates onto carnitine, an essential step for the mitochondrial uptake of long-chain fatty acids and their subsequent beta-oxidation in the mitochondrion. Plays an important role in triglyceride metabolism.
• Reactome Pathway:
  Peroxisomal protein import (R-HSA-9033241)
  Beta-oxidation of pristanoyl-CoA (R-HSA-389887)
• BioCyc Pathway: MetaCyc:HS01816-MON
