Abstract
In this study, we reported the complete genome sequence of Shewanella oncorhynchi for the first time. S. oncorhynchi Z-P2 is a bacterium that produces the siderophore putrebactin. Its genome consists of a circular chromosome of 5,034,612 bp with a G + C content of 45.4%. A total of 4544 protein-coding genes, 109 tRNAs and 31 rRNAs were annotated by the RAST. Five non-ribosomal peptide synthetase (NRPS) and polyketide synthetase (PKS) gene clusters were identified by the antiSMASH analysis. The pan-genome analysis of Z-P2 and 10 Shewanella putrefaciens revealed 9228 pan-gene clusters and 2681 core gene clusters, with Z-P2 having 618 unique gene clusters. Additionally, the gene cluster involved in putrebactin biosynthesis in Z-P2 was annotated, and the mechanism of putrebactin biosynthesis was analyzed. The putrebactin produced by Z-P2 was detected using UPLC-MS analysis, with an [M + H]+ molecular ion at m/z 373.21. These findings provide valuable support for further research on the genetic engineering of putrebactin biosynthetic genes of Z-P2 and their potential applications.
