CNA analysis of the MD simulations of N-SH2–pY, SB N-SH2–pY and C-SH2–pY. (A, B, C) Network centrality of the Cα atoms in N-SH2–pY (A), SB N-SH2–pY (B) and C-SH2–pY (C), respectively. The residues with the highest degree of centrality (hubs) are shown as spheres. The color-range from blue to red indicates the degree of betweenness centrality. (D, E, F) Representation of 250 communication pathways between three different regions of N-SH2–pY. Dynamic changes in the BC loop due to pY binding can be relayed to the EF (D) and BG (E) loops via the central β sheet, while αB mediates transfer of dynamic information between the EF and BG loops (F).
