Stereoview of the binding modes in R201Q–pPNG. (a) The binding mode between BlTreA and the glucosyl ring of pPNG. Water molecules are shown as cyan spheres. (b) The binding mode between BlTreA and the p-nitrophenol moiety of pPNG. (c) Structural alignment of R201Q–pPNG with NX-5–sucrose (PDB entry 4hph) showing the differences in substrate orientation. The bound pPNG (green) and sucrose (magenta) molecules are shown as sticks. (d) The binding mode of sucrose in the NX-5–sucrose complex. The bound sucrose is coloured magenta.
