Welcome to Actinomycete Research Group !


The filamentous soil bacteria Streptomyces produce various secondary metabolites such as antibiotics, immunosuppressants, antitumor compounds and herbicides. Actually, two thirds of antibiotics are produced by Streptomyces species. Therefore, this genus is one of the most important microorganisms in pharmaceutical and industrial fields.
We have been studying on Streptomyces by using various methods of biochemistry, molecular biology, and organic chemistry. The present main projects in our laboratory are as follows. We believe that these studies will contribute to produce new hybrid antibiotics with biological activity that are useful for human life.

(1) Analysis of biosynthetic machinery of secondary metabolites, and their structural redesign

(2) Analysis of signaling-molecules dependent regulatory cascade for secondary metabolite production

(3) Activation of silent secondary metabolite production through metabolic engineering (ggenome miningh)

(4) Integrative analysis of genomic structure, secondary metabolite production, regulation, and morphological differentiation

(5) Isolation, structural elucidation, and biological activity of microbial metabolites

(6) Others (Creation and functional analysis of highly functional molecules through interdisciplinary fusion)
