GII.12 P domain and B-trisaccharide interaction. The GII.12 P domain binds αfucose1-2 of type B HBGA with hydrogen bonds similar to those of GII.10, except that the carbonyl of Cys345 replaces that of Asn355. (A) Close-up surface and ribbon representation of the GII.12 P domain (colored as described in the legend to Fig. 1C and shown as a dimer) showing the bound B-trisaccharide (pink) and the electron density map contoured at 1.0 sigma. (B) GII.12 P domain and B-trisaccharide hydrophilic interactions. The asterisk on Arg346 indicates that a hydrogen bond interaction was slightly longer (3.3 Å) than the other bonds, usually less than 3.1 Å.
