    \u3000Plants produce many kinds of polysaccharides and microorganisms produce plant polysaccharides degradation-related enzymes to assimilate plant polysaccharides. Each enzyme has distinct functions in the degradation, and cooperative actions of these enzymes are crucial to degrade plant polysaccharides.<\/p>\n\n\n\n

      Our study focus on the identification and characterization of novel plant polysaccharides degradation-related enzymes from microorganisms, including fungi and metagenome.<\/p>\n\n\n\n

    \uff12. Evolution of Enzymes<\/strong><\/h2>\n\n\n\n

    \u3000Random and site-direct mutagenesis can change enzymatic properties, such as thermal stability and substrate specificity.  We use the mutagenesis techniques to improve the enzymatic activities and to elucidate the molecular mechanism of enzymatic reactions.<\/p>\n\n\n\n
