FIG. 6.

Stereoview of residues involved in the crystal contact interface at the MsrA active site. The active-site region is shown in yellow, and the region of the neighboring molecule containing Met-1 is shown in violet. Hydrogen bonds at a distance of 3.2 Å or less between the two protein molecules are shown as dashed lines, and water molecules are shown as red spheres. This figure was generated using BOBSCRIPT (14), GLR (version 0.5.0; National Institutes of Health; http://convent.nci.nih.gov/∼web/glr/glrhome.html), and POV-Ray (version 3.5; POV-Team; http://www.povray.org).
