Figure 3.

Backbone superposition of the 18 lowest energy NMR structures of free [blue, 1NMF.pdb (19)] and dT₇-bound (yellow) Bs-CspB. The five β-strands and their connecting loops are indicated. The r.m.s.d. values of dT₇-bound Bs-CspB of all 67 residues are 0.54 Å (backbone) and 0.94 Å (all heavy atoms). Main deviations between apo and holo form of Bs-CspB are located in loop β1–β2 (L₁₂) and loop β3–β4 (L₃₄).
