Mapping the Structural and Dynamical Features of Kinesin Motor Domains
Figure 5
Residue-residue plot of correlated motions.
The extent of correlation of atomic displacements for all residue pairs during ATP-like (upper triangle) and ADP-like (lower triangle) trajectory segments. The color scale runs from pink (for values ranging between −1 to −0.5), through white (−0.5 to 0.5) to cyan (0.5 to 1). Negative values are indicative of displacements along opposite directions, namely anticorrelated motions, whereas positive values depict correlated motions occurring along the same direction. Major secondary structure elements are labeled and indicated schematically with helices in black and strands in gray.
