Figure 3
The C-terminal D-alanine binding at the nest in vancomycin (taken from a model of vancomycin with a D-Ala-D-Ala peptide; PDB code 1van; Kelly et al., 1989). The atoms of the C-terminal D-alanine and the main-chain N atoms of the nest in vancomycin are portrayed in ball-and-stick representation. C atoms are grey, O atoms red, N atoms blue and Cl atoms green. Hydrogen bonds are shown as thin dashed lines. The sugar moieties of vancomycin are not shown. |
