FIG. 3. The active site for human galactose mutarotase. A close-up stereo view of those amino acid residues involved in sugar binding is displayed in a. The color coding for the ribbon representation is the same as in Fig. 2. The sugar is highlighted in grayish bonds. Possible hydrogen bonding interactions between the protein and the ligand are shown schematically in b. The dotted lines indicate distances equal to or below 3.2 Å.
