Principal Component analysis. (A) Projection of wild type RecU (RecUWT: shown in black), ΔNTR mutant RecU (RecUΔNTR: shown in red) and their complexes with HJ i.e. (RecUHJ: shown in green), (RecUΔNTR-HJ: shown in blue) along the first two eigenvectors. Sampling along both these eigenvectors is restricted in the presence of HJ. (B) Motion along eigenvector 1 showing rotation of mushroom cap with respect to the the stalk region. Two extreme structures along the direction of the eigenvector are shown in red and blue respectively in a surface representation of a backbone trace. (C) Motion along eigenvector 2 showing rocking of mushroom cap with respect to the stalk region.
