FIG. 3. Stereoviews of the structural conformation of SBA and the mutants complexed, respectively, with maltose. A, SBA (pH 5.4); B, M51T (pH 5.4); C, E178Y (pH 5.4); D, E178Y (pH 7.1); and E, N340T (pH 5.4). The electron density map (green, 2F[o] - F[c], contoured at 1.0 ) and the residues around the base catalyst and maltose are illustrated. The hydrogen bonds are indicated by broken lines (black). The mutated residues and the disordered conformations of maltose and the side chain of Glu380 in M51T are cyan. The disrupted hydrogen bonds in each mutants are indicated by broken lines (pink). This figure was generated using BOBSCRIPT (56) and Raster3D (55).
