Characterization of human ATP-binding cassette protein subfamily D reconstituted into proteoliposomes.

In mammals, four ATP-binding cassette (ABC) proteins belonging to subfamily D have been identified. ABCD1‒3 are located on peroxisomal membrane and play an important role in the transportation of various fatty acid-CoA derivatives, including very long chain fatty acid-CoA, into peroxisomes. ABCD4 is located on lysosomal membrane and is suggested to be involved in the transport of vitamin B<sub>12</sub> from lysosomes to the cytosol. However, the precise transport mechanism by which these ABC transporters facilitate the import or export of substrate has yet to be well elucidated. In this study, the overexpression of human ABCD1‒4 in the methylotrophic yeast Pichia pastoris and a purification procedure were developed. The detergent-solubilized proteins were reconstituted into liposomes. ABCD1‒4 displayed stable ATPase activity, which was inhibited by AlF<sub>3</sub>. Furthermore, ABCD1‒4 were found to possess an equal levels of acyl-CoA thioesterase activity. Proteoliposomes is expected to be an aid in the further biochemical characterization of ABCD transporters. << Less

Acyl-CoA thioesterase activity of peroxisomal ABC protein ABCD1 is required for the transport of very long-chain acyl-CoA into peroxisomes.
Kawaguchi K., Mukai E., Watanabe S., Yamashita A., Morita M., So T., Imanaka T.
The ABCD1 protein, one of the four ATP-binding cassette (ABC) proteins in subfamily D, is located on the peroxisomal membrane and is involved in the transport of very long chain fatty acid (VLCFA)-CoA into peroxisomes.

The ABCD1 protein, one of the four ATP-binding cassette (ABC) proteins in subfamily D, is located on the peroxisomal membrane and is involved in the transport of very long chain fatty acid (VLCFA)-CoA into peroxisomes. Its mutation causes X-linked adrenoleukodystophy (X-ALD): an inborn error of peroxisomal β-oxidation of VLCFA. Whether ABCD1 transports VLCFA-CoA as a CoA ester or free fatty acid is controversial. Recently, Comatose (CTS), a plant homologue of human ABCD1, has been shown to possess acyl-CoA thioesterase (ACOT) activity, and it is suggested that this activity is required for transport of acyl-CoA into peroxisomes. However, the precise transport mechanism is unknown. Here, we expressed human His-tagged ABCD1 in methylotrophic yeast, and characterized its ACOT activity and transport mechanism. The expressed ABCD1 possessed both ATPase and ACOT activities. The ACOT activity of ABCD1 was inhibited by p-chloromercuribenzoic acid (pCMB), a cysteine-reactive compound. Furthermore, we performed a transport assay with ABCD1-containing liposomes using 7-nitro-2-1,3-benzoxadiazol-4-yl (NBD)-labeled acyl-CoA as the substrate. The results showed that the fatty acid produced from VLCFA-CoA by ABCD1 is transported into liposomes and that ACOT activity is essential during this transport process. We propose a detailed mechanism of VLCFA-CoA transport by ABCD1. << Less
