FunFam 107: Putative lipoate-protein ligase A

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Lipoate--protein ligase. [EC: 6.3.1.20]
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.
