Stereo images of the active site structures. A, the accessible thiocyanate-bound active site of Rv3588c. Bubbles indicate the salt link between Asp-53 and Arg-55. B, comparison of the accessible (dark gray) and blocked (light gray) sites. Note in particular the shift of Asp-53 and the drastic changes of Ser-54 and Val-56.
