title: Structural proteins of Getah virus isolates from Japan and Malaysia.
abstract: Purified preparations of Getah virus strains have been analysed by sodium-dodecyl-sulphate polyacrylamide gel electrophoresis (SDS-PAGE) to reveal their structural proteins. Two envelope proteins (E1 and E2) and core protein (C) were found with the prototype AMM2021 strain both under reducing and nonreducing conditions, while separation of E1 and E2 was observed only under nonreducing conditions for 3 strains isolated in Japan. Limited digestion by Staphylococcus aureus V8 protease revealed difference in the peptide patterns of E1 between AMM2021 and Japanese isolates. Mobility of E1 and E2 was slower for the virus grown in BHK21 cells compared with the virus grown in Aedes albopictus cells, indicating host-controlled modification on the envelope glycoproteins.
