Whole-genome sequence of a novel, mangrove-derived streptomycete, Streptomyces malaysiense strain MUSC 136T
Since the discovery of streptomycin from Streptomyces griseus in the early 1940s, streptomycetes from various environments have been studied thoroughly for the ability to produce bioactive compounds including antibacterial, antioxidant, anticancer, antifungal as well as immunomodulatory properties. Previously identified as a novel strain from a mangrove forest in Malaysia, Streptomyces malaysiense MUSC 136T was selected for genome sequencing to explore its genomic potential. The genomic size comprises of 7,963,326 bp with a G+C content of 72.2% and a total of 6,614 proteincoding genes. As an attempt to investigate the types of biosynthetic gene cluster present in the MUSC 136T, the whole genome sequence was analyzed with a bioinformatics tool, antibiotics & Secondary Metabolite Analysis Shell (antiSMASH). Using the “strict” prediction method, a total of seven biosynthetic gene clusters which displayed similarity of more than 80% to known gene clusters including ectoine, geosmin as well as desferrioxamine. Apart from emphasizing the importance of streptomycetes from unique environments like mangrove forest, the current study serves as a foundation for future studies on the role of specific genes present in biosynthetic gene clusters which enables the exploitation of MUSC 136T to synthesize important and valuable compounds.
