Metabolite Identification
Common NameHeterobactin A
DescriptionHeterobactin A is a siderophore, a class of metabolites that play a crucial role in iron chelation and transport in microbial systems. This compound, characterized by its unique structure, features a peptide bond linking the guanidine group of an arginine residue to a 2,3-dihydroxybenzoate moiety, as elucidated through MS(n) analysis and NMR spectroscopy (PMID:24274668 ). Heterobactin A is known to form 1:1 ligand/metal complexes, which is critical for its function in iron acquisition (PMID:22539866 ). Variants of heterobactin A, such as heterobactin S1 and S2, exhibit sulfonation modifications on the aromatic rings, indicating the potential for structural diversity within this chemical class (PMID:24274668 ). Notably, heterobactin A is selectively recognized by the catecholate receptor Cir in E. coli, contrasting with heterobactin B, which is taken up by both E. coli and A. (PMID:11508844 ). The presence of heterobactin A alongside heterobactin B in various biological samples underscores its significance in microbial ecology and iron metabolism (PMID:33511442 ).
