DESCRIPTION

Also known as ACX11_CAEEL, acox-1.1, acox-1. Involved in the first step of peroxisomal beta-oxidation by catalyzing the desaturation of fatty acid-derived side chains (PubMed:25775534, PubMed:29537254, PubMed:27551084). Specifically, catalyzes the desaturation of fatty acids heptanoyl-CoA (C7), nonanoyl-CoA (C9), dodecanoyl-CoA (C12) and to a lesser extent pentanoyl-CoA (C5) and hexadecanoyl-CoA (C16), and hydroxylated fatty acid hydroxynonanoyl-CoA (PubMed:25775534, PubMed:29537254, PubMed:27551084). Also, catalyzes the desaturation fatty acid-derived side chains of ascaroside pheromones, which regulates development and behavior (PubMed:20610393, PubMed:25775534, PubMed:29537254, PubMed:29863473, PubMed:27551084). Specifically, shortens ascaroside with 5-carbon omega side chain (asc-omega-C5), 7-carbon side chain (asc-C7), 9-carbon side chain (asc-C9), 11-carbon side chain (asc-C11), 13-carbon side chain (asc-C13), 15-carbon side chain (asc-C15) and to a lesser extent ascarosides with 7-omega-carbon side chain (asc-omega-C7) (PubMed:25775534, PubMed:29537254, PubMed:27551084). Also shortens indol-3-carbonyl(IC)-ascarosides with 7-carbon side chain (IC-asc-C7) and to a lesser extent (IC)-ascarosides with 9-carbon side chain (IC-asc-C9) (PubMed:29863473). May associate and regulate the folding and/or the catalytic activity of other acyl-coenzyme A oxidases including acox-1.2, acox-1.3, acox-1.4 and acox-3 modulating the type of ascarosides produced (PubMed:25775534, PubMed:29537254, PubMed:29863473). In association with acox-1.3, catalyzes the desaturation of asc-C7-CoA but not of fatty acids or hydroxylated fatty acids (PubMed:25775534). Involved in the biosynthesis of asc-C6-MK (daumone 2) and asc-delta-C9 (daumone 3) but not asc-C7 (daumone 1); daumones are pheromones produced during unfavourable growth conditions which promote entry into the dauer stage (PubMed:20610393). Homodimer (Probable). Forms a heterodimer with acox-1.2 (PubMed:25775534). Forms a heterodimer with acox-1.3; the interaction may be important for the stability of acox-1.3 (PubMed:25775534).
