The chemical similarity of cellulose and chitin supports the idea that their corresponding hydrolytic enzymes would bind β-1,4-1inked glucose residues in a similar manner.A structural and mutational analysis was performed for the plant cellulolytic enzyme BGlu1 from Oryza sativa and the insect chitinolytic enzyme OfHex 1 from Ostrinia furnacalis.Although BGlul shows little amino-acid sequence or topological similarity with Of Hex 1, three residues (Trp490, Glu328, Va1327 in OfHex1, and Trp358, Tyr131 and Ile179 in BGlu1) were identified as being conserved in the +1 sugar binding site.
