Figure 1: Flexibility and depth of loops in TK.
From: Two strategies to engineer flexible loops for improved enzyme thermostability

(A) Comparison of B-Factor and depth of 39 loops in TK. The Y-axis is for both B-Factor and Depth (Å). (B) Correlation of B-Factor and depth for loops. (C) Normalized RMSF values versus residues of TK at different temperatures. (D) Difference of normalized RMSF values between 370 K and 300 K for each loop.
