The Award of Japan Society for Bioscience, Biotechnology, and Agrochemistry for young scientists (1997) 2. The Award of Hokuriku Branch, Japanese Biochemical Society for young scientists (2001) My research area is involved in “Applied Molecular Microbiology”. The aims of my laboratory are basic studies in microbial “Bioscience” and practical applications in new “Biotechnology”. To understand in depth microbial cell functions, we search, analyze and improve various functions and mechanisms of microorganisms including yeasts and bacteria from molecular, metabolic and cellular aspects. As the best scenario, novel findings and results of our basic studies can be applied to the molecular breeding for useful microorganisms, the production of valuable biomaterials (enzymes, amino acids) and the development of promising technologies to solve environmental issues.
1. Molecular mechanisms of stress-tolerance in yeast cells and its application for molecular breeding Yeast cells are exposed to environmental stresses during fermentations. Stress induces protein denaturation, generates abnormal proteins, and leads to growth inhibition or cell death. Therefore, stress tolerance is the key for application to industrial yeasts. We analyze various stress-tolerant mechanisms that can be applied to molecular breeding of industrial yeasts. i) Proline: Metabolic regulation, transport mechanism, physiological functions ii) N-Acetyltransferase Mpr1: Antioxidative mechanism, structural and functional analysis iii) Arginine/NO: Characterization of yeast NO synthase, downstream pathway and physiological roles of NO iv) Ubiquitin system: Degradation and repair mechanisms of stress-induced abnormal proteins, regulation of the uniqutin ligase Rsp5 activity v) Development of industrial yeast based on novel stress-tolerant mechanisms 2. Physiological roles and metabolic regulation of cysteine in Escherichia coli and their applications to cysteine fermentation Cysteine is an important amino acid both biologically and commercially. For achieving cysteine fermentation, we analyze the regulatory mechanisms regarding its biosynthesis, degradation and export, and try to construct cysteine-overproducing strains based on genomic information and metabolic engineering. 3. Folding mechanism and functional alteration of microbial proteases by new protein engineering Conventional protein engineering techniques have so far employed the introduction of mutagenesis in the protease domain to modify the enzymatic properties. A new approach, which we termed ‘pro-sequence engineering’, would be not only an important in investigations of protein folding, but also a promising technology for creating unique proteases with various beneficial properties.
