General Information

Description Encodes a protein with similarity to acyl-CoA dehydrogenases. Mutations in IBR3 render plants resistant to indole-3-butryic acid, a putative storage form of the biologically active auxin IAA (indole-3-acetic acid). IBR3 is hypothesized to carry out the second step in a, #946, -oxidation-like process of IBA metabolism in Arabidopsis. Though its subcellular location has not been determined, IBR3 has a peroxisomal targeting sequence and two other putative IBA metabolic enzymes (IBR1 and IBR10) can be found in this organelle. No specific enzymatic activity has been documented for IBR3, but double mutant analyses with CHY1 argue against a role for IBR3 in general fatty acid, #946, -oxidation. | IBA-RESPONSE 3 (IBR3) | FUNCTIONS IN: acyl-CoA dehydrogenase activity, oxidoreductase activity | INVOLVED IN: root hair elongation | EXPRESSED IN: 25 plant structures | EXPRESSED DURING: 15 growth stages | CONTAINS InterPro DOMAIN/s: Acyl-CoA oxidase/dehydrogenase, type1/2, C-terminal , Acyl-CoA oxidase/dehydrogenase, type 1 , Acyl-CoA dehydrogenase/oxidase , Acyl-CoA dehydrogenase/oxidase, N-terminal , Acyl-CoA oxidase/dehydrogenase, central domain , Acyl-CoA dehydrogenase/oxidase C-terminal , Protein kinase-like domain , Acyl-CoA dehydrogenase, N-terminal , Aminoglycoside phosphotransferase | BEST Arabidopsis thaliana protein match is: isovaleryl-CoA-dehydrogenase
