Metabolite Identification
Common NameRhizobactin 1021
DescriptionRhizobactin 1021 is a dihydroxamate siderophore produced by Sinorhizobium meliloti 1021, classified within the chemical class of siderophores. This metabolite plays a crucial role in iron acquisition, particularly under iron-limited conditions, and is essential for various biological processes such as biofilm formation and swarming motility. The inability of the rhb mutant to produce rhizobactin 1021 results in defects in biofilm formation, which cannot be rescued by iron-rich conditions (PMID:25887945 ). The siderophore is structurally similar to acinetoferrin and is imported via specific transporters like RhtX (PMID:23378574 ). Additionally, rhizobactin 1021 facilitates surface motility and swarming in S. meliloti, as indicated by transcriptome profiling of mutants lacking biosynthesis genes (PMID:20210991 ). Its role extends beyond S. meliloti, as it is also utilized by other bacteria, including Pseudomonas aeruginosa, demonstrating its importance in microbial ecology (PMID:16549659 ). Furthermore, the structural analysis has shown similarities between rhizobactin 1021 and other siderophores like schizokinen, highlighting its significance in iron homeostasis (PMID:16758117 ).
