beta-1,3-Glucanase F (BglF) from alkaliphilic Nocardiopsis sp. F96 is a single domain enzyme composed of only a catalytic domain. Chimeric BglFs with some carbohydrate-binding domains were constructed and characterized. By connecting the C-terminal additional domain of beta-1,3-glucanase H from Bacillus circulans IAM1165 and the chitin-binding domain of chitinase J from alkaliphilic Bacillus sp. J813, binding ability and hydrolyzing activity toward insoluble beta-1,3-glucans were both improved.
