ENZYME entry: EC 6.3.2.56

PURL: https://purl.expasy.org/enzyme/EC/6.3.2.56
Accepted Name
staphyloferrin B synthase
Reaction catalysed
2-[(L-alanin-3-ylcarbamoyl)methyl]-3-(2-aminoethylcarbamoyl)-2-hydroxypropanoate + 2-oxoglutarate + ATP = staphyloferrin B + AMP + diphosphate + H(+)
Comment(s)
  • Requires Mg(2+).
  • The enzyme, characterized from the bacterium Staphylococcus aureus, catalyzes the last step in the biosynthesis of the siderophore staphyloferrin B.
  • It belongs to a class of siderophore synthases known as type B nonribosomal peptide synthase-independent synthases (NIS).
  • Type B NIS enzymes recognize the delta-acid group of 2-oxoglutarate.
  • The enzyme forms a 2-oxoglutarate adenylate intermediate prior to ligation.
