Enzyme Information

Lipoate--protein ligase.
based on mapping to UniProt P32099
ATP + (R)-lipoate + a [lipoyl-carrier protein]-L-lysine = a [lipoyl- carrier protein]-N(6)-(lipoyl)lysine + AMP + diphosphate.
-!- This enzyme participates in lipoate salvage, and is responsible for lipoylation in the presence of exogenous lipoic acid. -!- The enzyme attaches lipoic acid to the lipoyl domains of certain key enzymes involved in oxidative metabolism, including pyruvate dehydrogenase (E(2) domain), 2-oxoglutarate dehydrogenase (E(2) domain), the branched-chain 2-oxoacid dehydrogenases and the glycine cleavage system (H protein). -!- Lipoylation is essential for the function of these enzymes. -!- The enzyme can also use octanoate instead of lipoate. -!- Formerly EC 2.7.7.63.
