ENZYME entry: EC

Accepted Name
D-ornithine--citrate ligase.
Reaction catalysed
ATP + citrate + D-ornithine <=> AMP + diphosphate + H(+) + N(5)-[(S)-citryl]-D-ornithine
  • Requires Mg(2+).
  • The enzyme, characterized from the bacterium Staphylococcus aureus, is involved in the biosynthesis of the siderophore staphyloferrin A.
  • It belongs to a class of siderophore synthases known as type A nonribosomal peptide synthase-independent synthases (NIS).
  • Type A NIS enzymes are responsible for the formation of amide or ester bonds between polyamines or amino alcohols and a prochiral carboxyl group of citrate.
  • The enzyme forms a citrate adenylate intermediate prior to ligation.
