FIG. 4. The CfTryX1 and CfTryXC43A structures. Stereoview overlay of the active sites of native CfTryX1 (carbon atoms colored green) and CfTryX1C43A (carbon atoms colored magenta), showing the adjustment in position of Ser-36 and Tyr-80 to compensate for the mutation of Cys-43. Dashed lines represent hydrogen bonding interactions.
