| Research Abstract |
The mechanism how cellulose synthase produces cellulose is not understood well, because this enzyme is very difficult to investigate and the enzymatic activity has been rarely analyzed in direct. In order to conduct direct analysis of cellulose synthase, three materials are prepared in this project :(i) recombinant proteins of cellulose synthase complex by E. coli expression system,(ii) c-di-GMP synthesis in vitro and in E. coli to fully activate the enzyme and(iii) enzymatic kinetics of cellulose-synthesizing activity in vitro. All of these are very important for direct analysis of cellulose synthase ; especially(i) is the first example in the world and an outstanding research resource. Thus this study has set up important tools for studying cellulose biosynthesis deeply.
