Figure 3
Interactions of P131 with CpIMPDH. (a) Interactions of the oxime and alkylamine. P131 is displayed in ball-and-stick representation and the protein residues are in ribbon representation with side chains depicted as sticks. Hydrogen bonds are shown in cyan. The dimer formed by subunits A and D is shown in tan and the corresponding waters are shown in brown. The BA dimer is shown in light blue and the corresponding waters are shown in dark blue. The CB dimer is shown in pink and the corresponding waters are shown in magenta. The DC dimer is shown in light green and the waters are shown in dark green. Residues within 5 Å of P131 are shown, with the exceptions of Asn191, residues 327–329 and the side chains of His166, Ile213 and Asn252, which have been omitted for clarity. (b) Interactions of the urea and the right side of P131 in the AD, CB and DC dimers. The color scheme is as above. (c) Interactions of the urea and the right side of P131 in the BC dimer. The color scheme is as above. (d) Interaction of the P131 Cl atom with the carbonyl O atom of Gly357′. The color scheme is the same as above. Hydrogen bonds are shown in cyan. The halogen bond is shown as a black dashed line. This figure was produced with UCSF Chimera (Pettersen et al., 2004BB29).
