Term Name: | dihydrolipoamide branched chain acyltransferase activity |
---|---|
Synonyms: | 2-methylpropanoyl-CoA:enzyme-6-N-(dihydrolipoyl)lysine:S-(2-methylpropanoyl)transferase activity, 2-methylpropanoyl-CoA:enzyme-N6-(dihydrolipoyl)lysine:S-(2-methylpropanoyl)transferase activity, dihydrolipoamide branched chain transacylase activity, dihydrolipoyl transacylase activity, dihydrolipoyllysine-residue (2-methylpropanoyl)transferase activity, enzyme-dihydrolipoyllysine:2-methylpropanoyl-CoA S-(2-methylpropanoyl)transferase activity |
Definition: | Catalysis of the reaction: N(6)-[(R)-dihydrolipoyl]-L-lysyl-[protein] + 2-methylpropanoyl-CoA = N(6)-[(R)-S(8)-2-methylpropanoyldihydrolipoyl]-L-lysyl-[protein] + CoA. In addition to transferring the 2-methylpropanoyl group when acting on the oxoacid corresponding with valine, this activity also transfers the 3-methylbutanoyl and S-2-methylbutanoyl groups when acting on the oxo acids corresponding with leucine and isoleucine. |
