Abstract:
This work deciphers the molecular and genetic bases used by strain PML1(12) of Caballeronia mineralivorans to mobilize iron and weather minerals. Through the combination of bioinformatics, chemical, and phylogenetic analyses, we characterized the siderophore produced by strain PML1(12) and the related genes. This siderophore was identified as rhizobactin and classified as a non-ribosomal peptide synthetase-independent siderophore (NIS). Contrary to the previously identified NIS synthetases that form siderophores containing citric acid, α-ketoglutarate, or succinic acid, our analyses revealed that rhizobactin contains malic acid in its structure, representing, therefore, the first identified NIS with such an acid and probably a new NIS category. Last, this work demonstrates for the first time the effectiveness at weathering minerals of a siderophore of the NIS family. Our findings offer relevant information for different fields of research, such as environmental genomics, microbiology, chemistry, and soil sciences.
