Figure 3
The active-site structure of the complex of D383A with raffinose (yellow sticks). Various residues (green sticks) are involved in binding interactions with glucose at the +1 subsite and fructose at the +2 subsite, as well as the galactosyl moiety at the −1 subsite. The catalytic residue Asp447 and the D383A mutation are also shown. One water molecule (cyan sphere) is located at the catalytic binding site to help stabilize the fructose moiety through hydrogen bonding. |
