Fig. 3. Putative scheme of peroxisomal fatty acid ß-oxidation with the free fatty acid and the acyl-CoA uptake route plus the role of Ant1p in
pH generation. FFA, free fatty acid; Fox1p, Fatty acyl-Coenzyme A oxidase; Fox2p, 3-hydroxyacyl-CoA dehydrogenase; Fox3p, 3-oxoacyl-CoA thiolase; Ant1p, Adenine nucleotide transporter; Pxa1p, peroxisomal ATP-binding cassette (ABC) transporter 1; Pxa2p, peroxisomal ATP-binding cassette (ABC) transporter 2, putative ATPase (postulated).
