Figure 5
Temperature-factor analysis of a native dimer. Chains K and L of the native free protein are shown as cartoons, where blue represents low and orange high B factors (Cα atoms). A colour scale bar illustrates the B-­factor range from 27 to 41 Å2. The C-terminal residues have the highest B factors (around 20% higher than the mean) in addition to the N-­terminal regions of the recognition helices. The core of the protein dimer, including the N-terminal half of helix 4 (shown in dark blue), has lower than average B factors as expected. This dimer has both alternative loop conformations, which are highlighted with arrows. The major conformation (A) has slightly higher B factors compared with the minor conformation (B), although both are close to the average for all residues.
