Figure 8. HPr side chain plasticity. (A) stereoview of superposition of selected regions of the interfaces of the HPr-IIAGlc and EIN-HPr complexes showing the different conformations of Phe48 of HPr; (B) superposition of regions of the two complexes showing the different conformations of Arg17 of HPr. HPr in the HPr-IIAGlc complex, red; HPr in the EIN-HPr complex, blue; EIN, purple; IIAGlc, green (from Wang et al., 2000a).
