Figure 4
Superposition of the apo and cellobiose-bound structures of PcCel6A. (a) The apo structure was observed in multiple conformations: the `relatively open' and `most open' conformations are shown. (b) Superposition of the relatively open apo structure and the cellobiose-bound structure. (c) Superposition of the most open apo structure and the cellobiose-bound structure. The width of the ribbon in each figure represents the r.m.s.d. value between the superposed conformations. The relative B factors were calculated for each apo and cellobiose-bound structure. |
