General Information | Comment | Organism |
---|---|---|
evolution | the enzyme is a member of the ATP-dependent carboxylate-amine/thiol ligase superfamily | Bacillus subtilis |
metabolism | L-amino-acid ligase RizA from Bacillus subtilis participates in the biosynthesis of the oligopeptide antibiotic rhizocticin | Bacillus subtilis |
additional information | L-amino acid ligases contain the ATP-grasp fold, which is composed of three conserved domains referred to as the A-domain (N-terminal domain), the B-domain (central domain) and the C-domain (C-terminal domain). These three domains commonly grasp the ATP molecule, and also provide binding sites for the Mg2+ ion and the amino-acid substrate | Bacillus subtilis |
