ENZYME entry: EC 6.3.2.55

Accepted Name
2-[(L-alanin-3-ylcarbamoyl)methyl]-3-(2-aminoethylcarbamoyl)-2- hydroxypropanoate synthase.
Reaction catalysed
(S)-2,3-diaminopropanoate + 2-[(2-aminoethylcarbamoyl)methyl]-2-hydroxybutanedioate + ATP <=> 2-[(L-alanin-3-ylcarbamoyl)methyl]-3-(2-aminoethylcarbamoyl)-2-hydroxypropanoate + AMP + diphosphate
Comment(s)
  • Requires Mg(2+).
  • The enzyme, characterized from the bacterium Staphylococcus aureus, is involved in the biosynthesis of the siderophore staphyloferrin B.
  • It belongs to a class of siderophore synthases known as type C nonribosomal peptide synthase-independent synthases (NIS).
  • Type B NIS enzymes recognize esterified or amidated derivatives of carboxylic acids.
  • The enzyme likely forms a 2-[(2-aminoethylcarbamoyl)methyl]-2- hydroxybutanedioate adenylate intermediate prior to ligation.
