Members of the genus have been isolated from geographically diverse ecosystems and exhibit considerable metabolic flexibility, as well as biotechnological and pathogenic properties in some species. This study reports the draft assembly and detailed sequence analysis of strain 56AF. The de novo-assembled genome is 4,556,707 bp in size and contains 4294 protein-coding and 95 RNA genes, including 88 tRNA, six rRNA, and one tmRNA operon. A repertoire of genes implicated in virulence, for example, hemolysin, hemolytic enterotoxins, colicin V, lytic proteins, and Nudix hydrolases, is present. The genome also contains a collection of genes of biotechnological interest, including esterases, lipase, auxins, chitinases, phytoene synthase and phytoene desaturase, polyhydroxyalkanoates, violacein, plastocyanin/azurin, and detoxifying compounds. Importantly, unlike other species, the 56AF genome contains genes for pore-forming toxin alpha-hemolysin, a type IV secretion system, among others. The analysis of the strain 56AF genome reveals the versatility, adaptability, and biotechnological potential of this bacterium. This study provides molecular information that may pave the way for further comparative genomics and functional studies involving -related isolates and improves our understanding of the global genomic diversity of species.
该属的成员已从地理上不同的生态系统中分离出来,表现出相当大的代谢灵活性,以及在某些物种中的生物技术和致病特性。本研究报告了菌株56AF的草图组装和详细序列分析。从头组装的基因组大小为4,556,707 bp,包含4294个蛋白质编码基因和95个RNA基因,包括88个tRNA、6个rRNA和1个tmRNA操纵子。存在一系列与毒力相关的基因,例如溶血素、溶血性肠毒素、大肠杆菌素V、裂解蛋白和Nudix水解酶。该基因组还包含一系列具有生物技术意义的基因,包括酯酶、脂肪酶、生长素、几丁质酶、八氢番茄红素合酶和八氢番茄红素去饱和酶、聚羟基脂肪酸酯、紫菌素、质体蓝素/天青蛋白以及解毒化合物。重要的是,与其他物种不同,56AF基因组包含形成孔道毒素α-溶血素、IV型分泌系统等的基因。对菌株56AF基因组的分析揭示了这种细菌的多功能性、适应性和生物技术潜力。本研究提供的分子信息可能为进一步涉及相关分离株的比较基因组学和功能研究铺平道路,并增进我们对物种全球基因组多样性的理解。
