ID 6.3.2.56 DE staphyloferrin B synthase. CA 2-[(L-alanin-3-ylcarbamoyl)methyl]-3-(2-aminoethylcarbamoyl)-2- CA hydroxypropanoate + 2-oxoglutarate + ATP = AMP + diphosphate + H(+) + CA staphyloferrin B. CC -!- Requires Mg(2+). CC -!- The enzyme, characterized from the bacterium Staphylococcus aureus, CC catalyzes the last step in the biosynthesis of the siderophore CC staphyloferrin B. CC -!- It belongs to a class of siderophore synthases known as type B CC nonribosomal peptide synthase-independent synthases (NIS). CC -!- Type B NIS enzymes recognize the delta-acid group of 2-oxoglutarate. CC -!- The enzyme forms a 2-oxoglutarate adenylate intermediate prior to CC ligation. DR Q2G1N1, SBNC_STAA8 ; //
