This entry represents the catalytic domain of a group of lipoyl ligases/lipoyltransferases, such as Lipoate-protein ligase A/B (LipA/B) from E.coli and mammalian lipoyltransferases [1-5]. These proteins catalyse the transfer of the lipoyl group from lipoyl-AMP to the specific lysine residue of lipoyl domains of lipoate-dependent enzymes. Lipoic acid is an essential cofactor of the alpha-ketoacid dehydrogenase complexes and the glycine cleavage system.	Domain
