Outline of Final Research Achievements

The ultimate goal of this research is proposition of the universal and evolved model of the mechanism for crystalline chitin degradation and utilization by chitinolytic bacteria. Therefore, "the role of the protein (CBP21) that promote degradation of crystalline chitin", "the importance of CBP21 for the biological and ecological function of the chitinolytic bacteria", "the mechanism for biodegradation of α-chitin that exists in nature more abundantly" were studied. As a results, it became clear that CBP21 is especially important for degradation and utilization of chitin close to natural condition, an amino acid residue with aromatic ring of big resonating structure at the entrance of the catalytic cleft of chitinase is very important for hydrolysis of highly crystalline chitin substrate, and that one chitinase molecule jump to another chitin chain in different orientation and begins hydrolysis in opposite direction.
