Figure 3. Putative active site of UDP-galactopyranose mutase.
a, Electrostatic plot of the surface of the protein. The
structure is orientated as Fig. 2a. The positive patch on the
surface is identified as the binding site for the negatively
charged sugar nucleotide substrate. Figure generated with
GRASP36. b, Close-up stereo view of the substrate binding cleft.
The orientation is as Fig. 2a. The absolutely conserved residues
and the flavin are shown in stick format. The color scheme is as
Fig. 2b.
