Figure 3

The auxin-binding site architecture. (A) The WTG hexamer showing three symmetrical auxin binding pockets each formed by four WTG monomers. (B) The side view of WTG hexamer showing auxin binding pockets sandwiched between two trimers. The auxin is shown as pink spheres whereas WTG hexamer is shown in cartoon representation. All the chains have been shown in different colours - chain A (blue), chain B (green), chain C (cyan), chain D (yellow), chain E (red), and chain F (orange). (C) Surface view of WTG tetramer demonstrating the size and shape of the auxin-binding pocket with auxin shown in white sticks. All the C-alpha atoms of different chains have been shown in different colors - chain A (blue), chain B (green), chain E (dark red), and chain F (orange) in surface view. The light red and dark blue color show surface of oxygen and nitrogen in all the four chains.
