Contributes to the transport of fatty acids and their derivatives (acyl CoAs) across the peroxisomal membrane. Provides acetate to the glyoxylate cycle in developing seedlings. Involved in pollen tube elongation, ovule fertilization, and seeds germination after imbibition (controls the switch between the opposing developmental programs of dormancy and germination), probably by promoting beta-oxidation of storage lipids during gluconeogenesis. Required for biosynthesis of jasmonic acid and conversion of indole butyric acid to indole acetic acid. Confers sensitivity to monofluoroacetic acid (FAc), a toxic acetate analog, and to 2,4-dichlorophenoxybutyric acid (2,4-DB) and indole-3-butyric acid (IBA), two precursors of auxin after beta-oxidation. an acyl-CoA(out) + ATP + H2O = ADP + an acyl-CoA(in) + H(+) + phosphate A number of isoforms are produced. According to EST sequences. Levels increase transiently after germination, before and during radicle emergence, especially in darkness (at protein level). Impaired germination after imbibition, rescued by sucrose treatment. Resistance to FAc, IBA and 2,4-DB. Compromised ability to convert acetate into soluble carbohydrate. Defective in lipid mobilization and accumulate acyl CoAs. Poor initiation of lateral root formation and smaller rosettes with fewer leaves than in wild-type. Crinkled and waxy leaves. Belongs to the ABC transporter superfamily. ABCD family. Peroxisomal fatty acyl CoA transporter (TC 3.A.1.203) subfamily.
