Figure 4.
Figure 4 CT motif. (a) The hydrophobic interactions between the catalytic domain and the CT motif. The side chains of residues involved in the hydrophobic interactions are represented and labelled. Residues in the catalytic domain are coloured grey, whereas those in the CT motif are coloured red. (b) Difference F[o] - F[c] electron-density map around the CT motif omitted for map calculation drawn in stereo with the refined model. The map was contoured at a level of 3.0 . Residues with atoms that participate in crystal contacts with neighbours are coloured cyan.
