Enzyme Information
| 2.3.1.12 |
Dihydrolipoyllysine-residue acetyltransferase.
based on mapping to UniProt P11961
Acetyl-CoA + enzyme N(6)-(dihydrolipoyl)lysine = CoA + enzyme N(6)- (S-acetyldihydrolipoyl)lysine.
-!- A multimer (24-mer or 60-mer, depending on the source) of this enzyme forms the core of the pyruvate dehydrogenase multienzyme complex, and binds tightly both EC 1.2.4.1 and EC 1.8.1.4. -!- The lipoyl group of this enzyme is reductively acetylated by EC 1.2.4.1, and the only observed direction catalyzed by EC 2.3.1.12 is that where the acetyl group is passed to coenzyme A.
