ABSTRACT
Semliki Forest, Sindbis and Chikungunya viruses were grown and radiolabeled with [3H]-amino acids in Vero cells. Analysis of virus infected cell lysates by two dimensional polyacrylamide gel electrophoresis resulted in detection of polypeptides of molecular, weights corresponding to those of E1, P62, ns60, ns70/72 for Semliki Forest virus, the C, E1, 6K, 14Κ, ΡΕ2, P97, ns60, ns82 for Sindbis virus and E1. P62, P97, ns70/72 for Chikungunya virus. Charge and molecular weight heterogeneity in the precursor polypeptide P62 of Semliki Forest virus was detected. Structural polypeptides e.g. E1 and E2 of Semliki Forest virus and C, E1, E2 of Sindbis virus and E1 of Chikungunya virus were detected when purified radiolabeled virus preparations were analyzed by two dimensional polyacrylamide gel-electrophoresis. Membrane glycoprotein Ε1 and E2 of Semliki Forest and Ε1 of Sindbis and Chikungunya viruses exhibited charge heterogeneity. In contrast to the marked difference in isoelectric points of E1 and E2 of Sindbis virus; E1 and E2 of Semliki Forest virus had almost identical isoelectric points.
