Figure 2

Detailed illustration of pThr binding in Rad53-FHA1 main binding site (A), Dun1-FHA second binding site (B), BRCT repeats (C) and WW domain (D). The binding areas are circled in red (see (1) on the left side). Residues surrounding pThr and pSer residues are in (2) and (3), respectively. Atom pairs that have charge interactions with phosphoresidues are shown with a blue dashed line. Figures are a snapshot of our MD simulations.
