Figure 3
Crystal packing. Colour code: L-TYR main core, blue; C-terminal domain, turquoise; A-TYR, purple; POM (TEW), green. (a) Crystal packing in 1 × 3 × 3 supercell. Four layers of protein (surface illustration) pointing alternately in opposing directions. The front layer exposes its POM side (front). (b) The same view as in (a) but with the first layer removed. Hence, the protein side is exposed (back). Here, the head-to-body alignment of L-TYR is discernible. (c) The image in (a) rotated by 90°, showing the sandwich-like layer stacking. (d) The insert shows a C-terminal domain attached notionally to A-TYR and clearly clashing with L-TYR of the adjacent asymmetric unit. (e) The image in (c) rotated by 90°. (f) The image in (e) tilted by 90° and rotated by 180°. One central L-TYR chain surrounded by the vicinal flanking chains (5× A-TYR, 2× L-TYR). An equivalent schematic illustration is shown on the right.
