Direct comparison of the four aldehyde oxidase enzymes present in mouse gives insight into their substrate specificities
Mammalian aldehyde oxidases (AOXs) are molybdo-flavoenzymes which are present in many tissues in various mammalian species, including humans and rodents. Different species contain a different number of AOX isoforms. In particular, the reasons why mammals other than humans express a multiplicity of tissue-specific AOX enzymes is unknown. In mouse, the isoforms mAOX1, mAOX3, mAOX4 and mAOX2 are p...
متن کاملThe four aldehyde oxidases of Drosophila melanogaster have different gene expression patterns and enzyme substrate specificities.
In the genome of Drosophila melanogaster, four genes coding for aldehyde oxidases (AOX1-4) were identified on chromosome 3. Phylogenetic analysis showed that the AOX gene cluster evolved via independent duplication events in the vertebrate and invertebrate lineages. The functional role and the substrate specificity of the distinct Drosophila AOX enzymes is unknown. Two loss-of-function mutant a...
متن کاملCross-species comparison of the metabolism and excretion of zoniporide: contribution of aldehyde oxidase to interspecies differences.
Excretion and metabolism of zoniporide were investigated in humans after intravenous infusion of [(14)C]zoniporide at an 80-mg dose. Bile was the primary route of excretion because 57% of dose was recovered in the feces after intravenous infusion. Zoniporide was primarily cleared via metabolism in humans. 2-Oxozoniporide (M1) was the major excretory and circulating metabolite in humans and was ...
متن کاملHepatic Aldehyde Oxidase
Previous reports on rabbit liver aldehyde oxidase described the purification and some properties of the enzyme (1) and the differential inhibition of electron transfer to various acceptors (2). The latter study furnished evidence for the participation of several electron carriers in the internal electron transport sequence of the enzyme. The present communication summarizes the results of studi...
متن کاملSubstrate 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...
