Figure 4
Comparison of the electrostatic surface potentials of UcaDntd (a) and F17cGntd (b). UcaDntd and F17cGntd are shown in surface representation with positively charged regions in blue, negatively charged regions in red and uncharged regions in white. The two structures are shown in the same orientation. (a) Residues in UcaDntd forming a small pocket overlapping with the known GlcNAc-binding pocket in F17cG are highlighted as sticks. All residues are labelled and atoms are coloured according to element: carbon in green, oxygen in red and nitrogen in deep blue. (b) The known binding site of F17cG is indicated with the bound GlcNAc shown in ball-and-stick representation in pale yellow. O and N atoms are coloured in the same way as in (a). |
