Figure 4
Active site and recognition of L-Ala-γ-D-Glu by BcYkfC. (a) Stereoview of a 2FoFc OMIT map, where L-Ala-γ-D-Glu and OCS238 were omitted from phasing/refinement, contoured at 1.5σ. (b) The extensive hydrogen-bond network in the active site of BcYkfC. Hydrogen bonds and distances are shown as dashed lines. (c) L-Ala-γ-D-Glu (stick representation; yellow C atoms) is located in the active site at the interface of the SH3b1 domain (blue) and the NlpC/P60 domain (red). (d) The interaction between L-Ala-γ-D-Glu and the active site of YkfC. This figure was generated using the program MOE 2008.10 (Chemical Computing Group Inc.).
