Problem:Paragraph: Using six monoclonal antibodies to epitopes a-f on the glycoprotein E2 of Semliki Forest virus (SFV) we found antigenic differences between E2 in infected cells and in virus particles, respectively, if glycosylation was impaired by 2-deoxy-D-glucose or inhibited by N-methyl-l-deoxynojirimycin. Furthermore we concluded that a conformational change of E2 takes place on virus budding. The composition and structure of carbohydrate side chains attached to viral glycoproteins is important for virus maturation. They may influence virus adsorption and penetration, transport of viral glycoproteins [12] , proteolytic cleavage of precursor proteins [1, 7] , association of spike glycoproteins [13] or their antigenicities [5, 11] . With Semliki Forest virus (SFV), a togavirus containing the nucleocapsid protein C and three envelope glycoproteins El, E2 and E3, we previously observed that virus maturation could be inhibited by impairment of glycosylation, e.g. by treatment of infected cells with tunicamycin or 2-deoxy-D-glucose (2-DG) [5] . Using polyclonal antisera, we have shown in addition that antigenicities of glycoproteins with no carbohydrate side chains (after treatment with tunicamycin) or with truncated chains (after treatment with 2-DG) differed from those of virus particles [2, 4, 9-]. Using six monoclonal antibodies (mabs) specific for six epitopes a-f on virion E2 we recently found changes in antigenicity of virion E2, if SFV was propagated in cells in presence of N-methyl-l-deoxynojirimycin (MdN): released, infectious virus particles contained mannose-rich carbohydrate side chains of the composition GI%ManT.8,9(GlcNAc)2; epitope d reacted very well, epitopes c and e reacted less, and epitopes a, b and f only very slightly [6, 10-].
