dihydrolipoamide branched chain acyltransferase activity
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.
