Abstract: Chitinase I (CHI1) of Bacillus circulans KA-304 forms protoplasts from Schizophyllum commune mycelia when the enzyme is combined with a-l,3-glucanase of B. circulans KA-304. CHI1 consists of an N-terminal unknown region and a C-terminal catalytic region classified into the glycoside hydrolase family-19 type. An N-terminal region-truncated mutant of CHI 1 (CatCHIl), which was expressed in Escherichia coli Rosetta-gami B (DE3), lost colloidal chitin- and powder chitin-binding activities. The colloidal chitin- and the powder chitin-hydrolyzing activities of CatCHIl were lower than those of CHI1, and CatCHIl was not effective in forming the protoplast. A fusion protein of the N-terminal region of CHI1 and green fluorescent protein (Nterm-GFP) was expressed in E. coli, and the fusion protein was adsorbed to colloidal chitin, powder chitin, and chitosan. Fluorescence microscopy analysis showed that Nterm-GFP bound to the S. commune cell-wall.
