has participant has participant coenzyme A(4-) acetyl-CoA(4-) N(6)-[(R)-dihydrolipoyl]-L-lysine residue N(6)-[(R)-S(8)-acetyldihydrolipoyl]-L-lysine residue dihydrolipoyllysine-residue acetyltransferase activity The only observed direction catalyzed by this activity is that where the acetyl group is passed to coenzyme A - that is, the right-to-left direction of that shown in the definition. S-acetyltransferase activity catalytic activity, acting on a protein
