Abstract excerpt
Chitosan oligosaccharides longer than a hexamer have higher bioactivity than polymer or shorter oligosaccharides, such as the monomer or dimer. In our previous work, we generated Paenibacillus fukuinensis chitosanase-displaying yeast using yeast cell surface displaying system and demonstrated the catalytic base. Here we investigated the specific function of putative four amino acid residues Trp159, Trp228,...
