Figure 4. Figure 4 View of the benzamidine-binding site in the rhFXI[370-607]-S434A,T475A,C482S,K437A-benzamidine structure. Benzamidine, a sulfate molecule in the oxyanion hole and a water molecule are shown as a ball-and-stick representation. The residues around benzamidine are shown as a stick representation. The hydrogen bonds between benzamidine and the protein are shown by black lines with bond distances labeled in Å.
