Substrate specificities of rat liver peroxisomal acyl-CoA oxidases: palmitoyl-CoA oxidase (inducible acyl-CoA oxidase), pristanoyl-CoA oxidase (non-inducible acyl-CoA oxidase), and trihydroxycoprostanoyl-CoA oxidase.
Rat liver peroxisomes contain three acyl-CoA oxidases:palmitoyl-CoA oxidase, pristanoyl-CoA oxidase, and trihydroxycoprostanoyl-CoA oxidase. The three oxidases were separated by anion-exchange chromatography of a partially purified oxidase preparation, and the column eluate was analyzed for oxidase activity with different acyl-CoAs. Short chain mono (hexanoyl-) and dicarboxylyl (glutaryl-)-CoAs...
متن کاملThe Arabidopsis acyl-CoA oxidase gene family.
A family of acyl-CoA oxidase isozymes catalyse the first step in the peroxisomal fatty acid beta-oxidation spiral. Our group and others have recently characterized four genes from this family in the model oilseed Arabidopsis. These genes encode isozymes with different acyl-CoA substrate specificities, which together encompass the full range of fatty acid chain lengths that exist in vivo. Here w...
متن کاملRegulation of purified rat liver acetyl CoA carboxylase by phosphorylation.
Acetyl CoA carboxylase was purified from liver of fasted-refed rats to near homogeneity, based on electrophoretic analysis and biotin content. These preparations contained an endogenous protein kinase that catalyzed the transfer of radioactive phosphate from [gamma-32P]ATP to acetyl CoA carboxylase, accompanied by a decrease in acetyl CoA carboxylase activity. Phosphate incorporated into acetyl...
متن کاملIsolation and structural characterization of the rat acyl-CoA oxidase gene.
Overlapping genomic clones containing the entire sequence of the rat acyl-CoA oxidase gene were isolated and characterized. This gene spans about 25 kilobases, and there are 14 exons and 13 introns. All of the exon-intron junction sequences agree with the GT/AG rule. The results of Southern blot analyses indicated that the gene occurs once per haploid genome. In a preceding paper (Miyazawa, S.,...
متن کاملPost-translational import of fatty acyl-CoA oxidase and catalase into peroxisomes of rat liver in vitro.
Total polysomal RNA of rat liver was translated in vitro in a rabbit reticulocyte lysate system. The translation products were mixed with a postnuclear supernatant fraction of rat liver and incubated post-translationally at 26 degrees C for 15-60 min. The import assay mixture was separated into a particulate fraction and supernatant by centrifugation, both of which were analyzed by immunoprecip...
