Figure 6
Structural comparison of GH18A (yellow), GH18B (blue) and OfChtI-CAD (white). The additional segments responsible for increasing the depth of the substrate-binding cleft and the residues comprising the chitin-binding plane in OfChtI-CAD are shown in pink and cyan, respectively. The (GlcNAc)6 in the structure of the complex of GH18A-E217L with (GlcNAc)6 is shown in green. |
