Figure 5.
FIG. 5. Stereoviews of the active site residues (green) and substrate (cyan) in SBA, GA, and BCX. The acid/base and nucleophile catalysts are shown in dark gray. CW refers to the catalytic water molecule. A, the structure of SBA complexed with maltose (Protein Data Bank code 1Q6C). B, the structure of GA complexed with acarbose (Protein Data Bank code 1AGM [PDB] ). C, the structure of BCX complexed with 2FXb [PDB] (Protein Data Bank code 1BVV [PDB] ). The hydrogen bonds are indicated by broken lines. This figure was generated using MOLSCRIPT (54) and Raster3D (55).
