Figure 2From: The SARS Coronavirus S Glycoprotein Receptor Binding Domain: Fine Mapping and Functional CharacterizationGlycosylation of S fragment containing the RBD. A) Expression of the three mutants on S317–518 where the potential sites of glycosylation at N318, N330 and N357 were individually converted to alanine. All the mutants appear to have similar molecular weights when compared to the wild type protein S317–518. B) Cell binding data of the same mutants.Back to article page
