| Outline of Final Research Achievements |
Toward to the realization of “Biorefinery”, we aimed to increase the efficiency of enzymatic saccharification, and attempted to elucidate the enzymatic reaction mechanism involved in cellulases efficient crystalline cellulose degradation. Specifically, we attempted to elucidate such a mechanism through the biochemical experiment, HS-AFM observation, and protein crystal structure analysis of cellulase SaCel6B derived from Actinomycetes. As a result of experiments and observations, we found two amino acid residues involved in efficient crystalline cellulose degradation of cellulase SaCel6B and clarified the importance of these residues. Based on information of such amino acid residues, it could be possible to try to discover cellulases with highly saccharification efficiency or synthesize novel cellulases with high efficiency of saccharification.
