Comparative analyses of the Adenylate Kinases. The Bhattacharya Coefficient (BC) for all pairwise comparison in the alignment of the Adenylate Kinases (A). The plot shows that the ligand-bound and ligand-free structures cluster in two distinct groups. The clustering obtained with RMSIP is also shown (B). The deformation energy plot (C) and the comparative normalised fluctuations plot (D) show the values of the parts that are aligned to all other structures in the alignment as solid lines, and the parts aligned with gaps in other structures as dotted lines. The NMP and LID domains are marked by black and grey points, respectively.
