Figure 4.
Fig. 4. Superimposed illustrations of the area near the sugar-binding sites of type C and type A HA1. (a) Close-up view of the 2α-repeat region of type C HA1 superimposed on the same region of type A HA1 with a Gal molecule model. The putative sugar-binding residues as observed in type C HA1 (pink) and their counterparts in type A HA1 (blue). Residue labels are indicated for type C HA1; those from the type A HA1 structure are in parentheses. (b) Overlay of the two types of HA1 on the 2γ-repeat region with a stick-modeled Gal.
