Figure 3.
Figure 3. Stereoview of the MTAP trimer. The trimer is viewed down the molecular/crystallographic threefold axis. Each subunit is shown in a different color, with MTA and sulfate modeled in red in each of the three active sites. Broken lines indicate residues 225–229, which are missing in the final model. (The figure was produced using the program MOLSCRIPT [41].)
