Figure 2

X-ray crystal structures of closed and open conformations of prothrombin. (A) Structure of the prothrombin mutant S101C/A470C (proTCC) solved at 4.0Å resolution (PDB ID: 6C2W) (15). (B) Structure of the prothrombin mutant Δ154–167 (proTΔ154–167) solved at 2.2Å resolution (PDB ID: 5EDM) (33). Key residues Trp547 in the protease domain and Tyr93 in the kringle-1 are shown in magenta.
