ENZYME entry: EC 6.3.2.38

Accepted Name
N(2)-citryl-N(6)-acetyl-N(6)-hydroxylysine synthase.
Alternative Name(s)
N(alpha)-citryl-N(epsilon)-acetyl-N(epsilon)-hydroxylysine synthase.
Reaction catalysed
ATP + citrate + N(6)-acetyl-N(6)-hydroxy-L-lysine <=> AMP + diphosphate + N(2)-citryl-N(6)-acetyl-N(6)-hydroxy-L-lysine
Cofactor(s)
Mg(2+).
Comment(s)
  • Requires Mg(2+).
  • The enzyme is involved in the biosynthesis of aerobactin, a dihydroxamate siderophore.
  • It belongs to a class of siderophore synthases known as type A nonribosomal peptide synthase-independent synthases (NIS).
  • Type A 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 is believed to form an adenylate intermediate prior to ligation.
  • Formerly EC 6.3.2.27.
