Purification and characterization of variants of acyl-CoA-binding protein in the bovine liver.

Four differently modified forms of acyl-CoA-binding protein (ACBP) were identified in ACBP purified from bovine liver. The majority of the purified ACBP was focused at pH 5.9 in isoelectric focusing and could be shown to be N-acetylated ACBP without any further modifications. Two minor peaks were focused at pH 5.25 and 4.85 respectively. Mass spectrometry and sequence determination showed that the pI 5.25 form was acetylated at Lys18 and that the pI 4.85 form was malonylated in the same position. Furthermore, it could be shown that non-enzymic glycosylation occurred during purification. The acetylated and malonylated variants of ACBP were only found in adult cattle.

Comparison of the binding affinities of acyl-CoA-binding protein and fatty-acid-binding protein for long-chain acyl-CoA esters.

Bovine and rat liver acyl-CoA-binding proteins (ACBP) were found to exhibit a much higher affinity for long-chain acyl-CoA esters than both bovine hepatic and cardiac fatty-acid-binding proteins (hFABP and cFABP respectively). In the Lipidex 1000- as well as the liposome-binding assay, bovine and rat hepatic ACBP effectively bound long-chain acyl-CoA ester, h- and c-FABP were, under identical conditions, unable to bind significant amounts of long-chain acyl-CoA esters. When FABP, ACBP and [1-14C]hexadecanoyl-CoA were mixed, hexadecanoyl-CoA could be shown to be bound to ACBP only. The experimental results give strong evidence that ACBP, and not FABP, is the predominant carrier of acyl-CoA in liver.
