This is a family of glycine cleavage H-proteins, part of the glycine cleavage multienzyme complex (GCV) found in bacteria and the mitochondria of eukaryotes. GCV catalyses the catabolism of glycine in eukaryotes. A lipoyl group is attached to a completely conserved lysine residue. The H protein shuttles the methylamine group of glycine from the P protein to the T protein.
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 ...
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.
This is the C-terminal domain of a bacterial lipoate protein ligase. There is no conservation between this C-terminus and that of vertebrate lipoate protein ligase C-termini, but both are associated with the domain BPL_LipA_LipB Pfam:PF03099, furthe ...
This is the C-terminal domain of a bacterial lipoate protein ligase. There is no conservation between this C-terminus and that of vertebrate lipoate protein ligase C-termini, but both are associated with the domain BPL_LipA_LipB Pfam:PF03099, further upstream. This domain is required for adenylation of lipoic acid by lipoate protein ligases. The domain is not required for transfer of lipoic acid from the adenylate to the lipoyl domain. Upon adenylation, this domain rotates 180 degrees away from the active site cleft. Therefore, the domain does not interact with the lipoyl domain during transfer.
