Enzyme Information

2.3.1.61

Dihydrolipoyllysine-residue succinyltransferase.

based on mapping to UniProt P0AFG6

Succinyl-CoA + enzyme N(6)-(dihydrolipoyl)lysine = CoA + enzyme N(6)- (S-succinyldihydrolipoyl)lysine.

-!- A multimer (24-mer) of this enzyme forms the core of the multienzyme complex, and binds tightly both EC 1.2.4.2 and EC 1.8.1.4. -!- The lipoyl group of this enzyme is reductively succinylated by EC 1.2.4.2, and the only observed direction catalyzed by EC 2.3.1.61 is that where this succinyl group is passed to coenzyme A.
