Outline of Final Research Achievements |
GH family 18 (GH18) chitinases are known to have some additional domains, such as a chitin-binding domain (ChBD), a fibronectin type III-like domain (FnIIID) and a chitinase insertion domain (CID), as well as a GH18 catalytic domain. The role of additional domains in chitin hydrolysis remains unclear to date. In order to clarify the role of the additional domains, many chimeric enzymes were prepared and characterized. The CID proved to contribute to exo-type digestion and processivity against soluble and insoluble chitins. Furthermore, the ChBD and FnIIID might also contribute to exo-type digestion and processivity against insoluble chitin.
