Novel functions of acyl-CoA thioesterases and acyltransferases as auxiliary enzymes in peroxisomal lipid metabolism.
Peroxisomes are single membrane bound organelles present in almost all eukaryotic cells, and to date have been shown to contain approximately 60 identified enzymes involved in various metabolic pathways, including the oxidation of a variety of lipids. These lipids include very long-chain fatty acids, methyl branched fatty acids, prostaglandins, bile-acid precursors and xenobiotics that are eith...
متن کاملTwo families of acyl-CoA thioesterases in Arabidopsis.
We have identified two families of acyl-CoA thioesterase (ACHs) in Arabidopsis thaliana. One family, consisting of AtACH1 and AtACH2, appears to be peroxisomal, as they have type-1 peroxisomal targeting sequences. The other family, consisting of AtACH4 and AtACH5, resides in the endoplasmic reticulum, as shown by green fluorescent protein studies. AtACH2 has been overexpressed in Escherichia co...
متن کاملA revised nomenclature for mammalian acyl-CoA thioesterases/hydrolases.
Acyl-CoA thioesterases, also known as acyl-CoA hydrolases, are a group of enzymes that hydrolyze CoA esters such as acyl-CoAs (saturated, unsaturated, branched-chain), bile acid-CoAs, CoA esters of prostaglandins, etc., to the corresponding free acid and CoA. However, there is significant confusion regarding the nomenclature of these genes. In agreement with the HUGO Gene Nomenclature Committee...
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...
متن کاملCloning of cDNA coding for peroxisomal acyl-CoA oxidase from the yeast Candida tropicalis pK233.
Candida tropicalis pK233 cells were grown with n-alkanes as carbon source to induce the synthesis of peroxisomal proteins and the proliferation of peroxisomes. Poly-(A)+ RNA was isolated and used to construct a cDNA library by insertion of double-stranded reverse transcripts into the Pst I site of pBR322 followed by cloning in Escherichia coli. Clones complementary to mRNAs induced by growth on...
