Abstract
The proteins of purified enterovirus type 70 grown in rhabdomyosarcoma cells and the intracellular proteins at 4 to 5 h after infection have been examined by polyacrylamide gel electrophoresis. Virions contained four proteins: P-1 (35,000, daltons) P-2 (28,000, daltons) P-3 (27,000, daltons) and P-4 (9,000 daltons). Further, addition of ZnCl2 to infected cultures inhibited virus plaque development and interfered with post-translational cleavage.
