Abstract

Microorganisms serve as attractive resources, owing to their ability to synthesize structurally-diverse substances
with various bioactivities. Within the Bacteria domain, members of the genus Streptomyces have demonstrated remarkable
ability to produce clinically useful, secondary metabolites such as anticancer, antioxidants, antivirals and antibacterials.
Streptomyces pluripotens MUSC 135T was isolated as novel strain from mangrove forest in Malaysia. This strain exhibited
broad spectrum bacteriocin against several pathogens including methicillin-resistant Staphylococcus aureus (MRSA) strain
ATCC BAA-44, Salmonella typhi ATCC 19430T and Aeromonas hydrophila ATCC 7966T. Thus, the strain was selected for
whole genome sequencing as an attempt to explore its bioactive potential. Here we report the first complete genome of S.
pluripotens MUSC 135T genome which comprise of 7.35 Mbp with G+C content of 69.9 %. A total of 6,404 open reading
frames (ORFs) were predicted, along with 18 rRNA and 69 tRNA genes. Using bacteriocin mining tool, BAGEL detected
eights gene clusters associated with bacteriocin production including lanthipeptides and linear azol(in)e-containing peptides
(LAPs). Members of Streptomyces have contributed greatly towards improving lives, particularly against deadly infections
and chronic diseases. The availability of S. pluripotens MUSC 135T genome sequence has opened new window for drug
discovery, particularly for effective drugs against harmful pathogens such as MRSA and certainly deserves further detailed
study.
