Glycosylation of the cauliflower mosaic virus capsid polypeptide.
Evidence is presented for the glycosylation of the cauliflower mosaic virus (CaMV) capsid polypeptide. Fluorescent derivatives of concanavalin A (Con A) were shown to bind specifically to the dissociated CaMV capsid polypeptides in polyacrylamide gels. Con A also bound specifically to intact CaMV, so inhibiting the attachment of virus-specific antibodies. The role of carbohydrate residues in CaMV antigenicity is evaluated.
