Table 1. Variation of highly specific N-glycosylation sites of 68 strains in comparison to CV777.

South China isolates are indicated in boldface type, with the dash indicating possession of the same sites, and the “N” indicating that the strain did not contain the site, or the sites were not high-specificity sites. These predictions were done on the Asn-Xaa-Ser/Thr sequons.
