Figure 4. B-factors of residues of BthII1283 based on average for main chain atoms.

(A) Asymmetric unit of BthII1283/SAH crystals with monomer A on the left and monomer B on the right. (B) Asymmetric unit of BthII1283/SAH/1,6-DDMT crystals with monomer A on the left and monomer B on the right. The darkest shade of blue corresponds to the minimum residue B-factor (10.5 in panel A and 14.4 in panel B), white corresponds to the average residue B-factor (17.8 in panel A and 23.5 in panel B), and the darkest shade of red corresponds to a residue B-factor five or more standard deviations above the average (59.9 in panel A and 68.3 in panel B). SAH and 1.6-DDMT are shown as balls and sticks.
