Figure 5.
Figure 5. Stereo views of the sugar binding structures in the XBD with the F[obs] - F[calc] omit electron density maps contoured at 3s. (a) In the subdomain a in the FXYN/X2 complex, (b) subdomain g in the FXYN/X3 complex, (c) subdomain g in the FXYN/Glc complex, (d) subdomain a in the FXYN/Gal complex, (e) subdomain g in the FXYN/Lac complex, and (f) subdomain a in the FXYN/Lac complex from a different view point. Hydrogen bonding interactions between the enzyme and sugars are indicated by broken lines. Carbon numbers of bound xylose are indicated.
