Figure 3. Fig. 3. The Coh-Doc interface of the native (in orange) and S45A-T46A mutant (in blue) type I complexes. (a) Stick representation of the hydrophobic residues on the surface of the cohesin modules (in ribbon representation). The dockerin modules are represented by their molecular surfaces. (b) Stick representation of the hydrophobic residues on the surface of the dockerin modules (in ribbon representation). The cohesin modules are represented by their molecular surfaces. (c) Stick representation of the hydrogen-bond network in the interface of the Coh-DocS45A-T46A complex (in ribbon representation). Carbon atoms are shown in yellow, oxygens are shown in red, and nitrogens are shown in blue. All pictures were produced with the CCP4 mg program (42).
