ID   6.3.2.55
DE   2-[(L-alanin-3-ylcarbamoyl)methyl]-3-(2-aminoethylcarbamoyl)-2-
DE   hydroxypropanoate synthase.
CA   (S)-2,3-diaminopropanoate + 2-[(2-aminoethylcarbamoyl)methyl]-2-
CA   hydroxybutanedioate + ATP = 2-[(L-alanin-3-ylcarbamoyl)methyl]-3-
CA   (2-aminoethylcarbamoyl)-2-hydroxypropanoate + 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
CC       C nonribosomal peptide synthase-independent synthases (NIS).
CC   -!- Type B NIS enzymes recognize esterified or amidated derivatives of
CC       carboxylic acids.
CC   -!- The enzyme likely forms a 2-[(2-aminoethylcarbamoyl)methyl]-2-
CC       hydroxybutanedioate adenylate intermediate prior to ligation.
