CC -!- FUNCTION: Involved in the intramitochondrial synthesis of
CC acylcarnitines from accumulated acyl-CoA metabolites. Reconverts
CC acylcarnitines back into the respective acyl-CoA esters that can then
CC undergo beta-oxidation, an essential step for the mitochondrial uptake
CC of long-chain fatty acids and their subsequent beta-oxidation in the
CC mitochondrion. Active with medium (C8-C12) and long-chain (C14-C18)
CC acyl-CoA esters. {ECO:0000250|UniProtKB:P23786}.
