| pubmed-article:454617 | pubmed:abstractText | An enzyme which catalyses oxidative decarboxylation of branched-chain alpha-keto acids was extracted from rat liver mitochondria with the aid of NaClO4. Purification yielded a product which appeared homogenous upon electrophoresis. Some kinetic data are reported; however, the enzyme is inactive with alpha-ketoisovalerate. The tenacity of binding to mitochondria, specificity, and other features, suggest that the decarboxylase may be a component of an enzyme complex named alpha-ketoisocaproate: alpha-keto-beta-methylvalerate dehydrogenase. | lld:pubmed |
