Oxidative decarboxylation of branched-chain 2-oxo Fatty acids by higher plant peroxisomes.

چکیده
Peroxisomes from mung bean (Vigna radiata L.) hypocotyls catalyze, in the presence of branched-chain 2-oxo fatty acid, CoASH and NAD, the release of CO(2), and the formation of NADH and acyl-CoA. The acyl-CoA contains one carbon atom less than the branched-chain 2-oxo fatty acid and serves as substrate for the peroxisomal acyl-CoA oxidase. CO(2) release, NADH and acyl-CoA formation occur in 1:1:1 stoichiometry. For the first time the data demonstrate directly the oxidative decarboxylation of branched-chain 2-oxo fatty acids in higher plants and a location of this activity in the peroxisomes.

Partial purification and properties of branched-chain 2-oxo acid dehydrogenase of ox liver.
1. A branched-chain 2-oxo acid dehydrogenase was partially purified from ox liver mitochondria. 2. The preparation oxidized 4-methyl-2-oxopentanoate, 3-methyl-2-oxobutyrate and D- and L-3-methyl-2-oxopentanoate. The apparent Km values for the oxo acids and for thiamin pyrophosphate, CoA, NAD+ and Mg2+ were determined. 3. The oxidation of each oxo acid was inhibited by isovaleryl (3-methylbutyry...

The phosphorylation state of both complexes in extracts of mitochondria from rat liver, kidney, heart and skeletal muscle was shown to infl...
متن کاملPyruvate decarboxylase catalyzes decarboxylation of branched-chain 2-oxo acids but is not essential for fusel alcohol production by Saccharomyces cerevisiae.
The fusel alcohols 3-methyl-1-butanol, 2-methyl-1-butanol, and 2-methyl-propanol are important flavor compounds in yeast-derived food products and beverages. The formation of these compounds from branched-chain amino acids is generally assumed to occur via the Ehrlich pathway, which involves the concerted action of a branched-chain transaminase, a decarboxylase, and an alcohol dehydrogenase. Pa...

Chain elongation and 2-hydroxylation pathways, which are specific for very long chain fatty acids ( >C&), have been found in the yeast, Candida utitis. The chain elongation system acts specifically on fatty acids of chain length C2,, to CZ4; there is no detectable elongation of Cl* and only trace . . . actrvrty with C&,. The product of the elongation enzyme or enzymes is C& when Co, C&, or C24 ...
