RL Submitted (NOV-2023) to UniProtKB.
CC -!- FUNCTION: Catalyzes the transfer of the acyl group of long-chain fatty
CC acid-CoA conjugates onto carnitine, an essential step for the
CC mitochondrial uptake of long-chain fatty acids and their subsequent
CC beta-oxidation in the mitochondrion. {ECO:0000256|ARBA:ARBA00043926}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-carnitine + hexadecanoyl-CoA = CoA + O-hexadecanoyl-(R)-
CC carnitine; Xref=Rhea:RHEA:12661, ChEBI:CHEBI:16347,
CC ChEBI:CHEBI:17490, ChEBI:CHEBI:57287, ChEBI:CHEBI:57379; EC=2.3.1.21;
CC Evidence={ECO:0000256|ARBA:ARBA00043805};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:12662;
CC Evidence={ECO:0000256|ARBA:ARBA00043805};
CC -!- PATHWAY: Lipid metabolism; fatty acid beta-oxidation.
CC {ECO:0000256|ARBA:ARBA00005005}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi-
CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Mitochondrion
CC outer membrane {ECO:0000256|ARBA:ARBA00004374}; Multi-pass membrane
CC protein {ECO:0000256|ARBA:ARBA00004374}.
CC -!- SIMILARITY: Belongs to the carnitine/choline acetyltransferase family.
CC {ECO:0000256|ARBA:ARBA00005232, ECO:0000256|RuleBase:RU003801}.
