DE   L-2,3-diaminopropanoate--citrate ligase.
AN   2-[(L-alanin-3-ylcarbamoyl)methyl]-2-hydroxybutanedioate synthtase.
CA   (S)-2,3-diaminopropanoate + ATP + citrate = 2-[(L-alanin-3-
CA   ylcarbamoyl)methyl]-2-hydroxybutanedioate + AMP + diphosphate.
CC   -!- Requires Mg(2+).
CC   -!- The enzyme, characterized from the bacterium Staphylococcus aureus,
CC       is involved in the biosynthesis of the siderophore staphyloferrin B.
CC   -!- It belongs to a class of siderophore synthases known as type A
CC       nonribosomal peptide synthase-independent synthases (NIS).
CC   -!- Type A NIS enzymes are responsible for the formation of amide or
CC       ester bonds between polyamines or amino alcohols and a prochiral
CC       carboxyl group of citrate.
CC   -!- The enzyme forms a citrate adenylate intermediate prior to ligation.
