ID 6.3.2.58 DE D-ornithine--citrate ligase. CA ATP + citrate + D-ornithine = AMP + diphosphate + H(+) + N(5)-[(S)- CA citryl]-D-ornithine. CC -!- Requires Mg(2+). CC -!- The enzyme, characterized from the bacterium Staphylococcus aureus, CC is involved in the biosynthesis of the siderophore staphyloferrin A. 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. DR Q2FW70, SFNAD_STAA8; //
