Accepted name: |
2-[(L-alanin-3-ylcarbamoyl)methyl]-3-(2-aminoethylcarbamoyl)-2-hydroxypropanoate synthase |
Reaction: |
ATP + 2-[(2-aminoethylcarbamoyl)methyl]-2-hydroxybutanedioate + L-2,3-diaminopropanoate = AMP + diphosphate + 2-[(L-alanin-3-ylcarbamoyl)methyl]-3-(2-aminoethylcarbamoyl)-2-hydroxypropanoate |
Glossary: |
staphyloferrin B = 5-[(2-{[(3S)-5-{[(2S)-2-amino-2-carboxyethyl]amino}-3-carboxy-3-hydroxy-5-oxopentanoyl]amino}ethyl)amino]-2,5-dioxopentanoate |
Other name(s): |
sbnF (gene name) |
Systematic name: |
2-[(2-aminoethylcarbamoyl)methyl]-2-hydroxybutanedioate:L-2,3-diaminopropanoate ligase {2-[(L-alanin-3-ylcarbamoyl)methyl]-3-(2-aminoethylcarbamoyl)-2-hydroxypropanoate-forming} |
Comments: |
Requires Mg2+. 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 C 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. |
