The active site and the mutation point in the three-dimensional structure of Trichoderma reesei BGLII (PDBID: 3AHY). The catalytic acid/base, Glu165, the catalytic nucleophile, Glu367, and the mutation residue in this study, Val409 are shown as CPK model. All other residues are displayed as ribbon model in a and residues from Phe323 to Tyr360 are omitted in b
