biotin-lipoate ligase family; This family includes biotin protein ligase (BPL), lipoate-protein ligase A (LplA) and octanoyl-[acyl carrier protein]-protein acyltransferase (LipB). Biotin is covalently attached at the active site of certain enzymes that transfer carbon dioxide from bicarbonate to organic acids to form cellular metabolites. Biotin protein ligase (BPL) is the enzyme responsible for attaching biotin to a specific lysine at the active site of biotin enzymes. Biotin attachment is a two step reaction that results in the formation of an amide linkage between the carboxyl group of biotin and the epsilon-amino group of the modified lysine. Lipoate-protein ligase A (LplA) catalyses the formation of an amide linkage between lipoic acid and a specific lysine residue in lipoate dependent enzymes.

lipoyltransferase and lipoate-protein ligase; One member of this group of proteins is bovine lipoyltransferase, which transfers the lipoyl group from lipoyl-AMP to the specific Lys of lipoate-dependent enzymes. However, it does not first activate lipoic acid with ATP to create lipoyl-AMP and pyrophosphate. Another member of this group, lipoate-protein ligase A from E. coli, catalyzes both the activation and the transfer of lipoate. Homology between the two is full-length, except for the bovine mitochondrial targeting signal, but is strongest toward the N-terminus. [Protein fate, Protein modification and repair]

lipoate-protein ligase; Lipoate-protein ligase A (LplA) catalyzes the formation of an amide linkage between free lipoic acid and a specific lysine residue of the lipoyl domain in lipoate dependent enzymes, similar to the biotinylation reaction mediated by biotinyl protein ligase (BPL). The two step reaction includes activation of exogenously supplied lipoic acid at the expense of ATP to lipoyl-AMP and then transfer to the epsilon-amino group of a specific lysine residue of the lipoyl domain of the target protein.

Bacterial lipoate protein ligase C-terminus; 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 pfam03099, 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.

Biotin/lipoate A/B protein ligase family; This family includes biotin protein ligase, lipoate-protein ligase A and B. Biotin is covalently attached at the active site of certain enzymes that transfer carbon dioxide from bicarbonate to organic acids to form cellular metabolites. Biotin protein ligase (BPL) is the enzyme responsible for attaching biotin to a specific lysine at the active site of biotin enzymes. Each organizm probably has only one BPL. Biotin attachment is a two step reaction that results in the formation of an amide linkage between the carboxyl group of biotin and the epsilon-amino group of the modified lysine. Lipoate-protein ligase A (LPLA) catalyzes the formation of an amide linkage between lipoic acid and a specific lysine residue in lipoate dependent enzymes. The unusual biosynthesis pathway of lipoic acid is mechanistically intertwined with attachment of the cofactor.
