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.
利用聚丙烯酰胺凝胶电泳对在横纹肌肉瘤细胞中培养的纯化70型肠道病毒的蛋白质以及感染后4至5小时的细胞内蛋白质进行了检测。病毒粒子包含四种蛋白质:P-1(35,000道尔顿)、P-2(28,000道尔顿)、P-3(27,000道尔顿)和P-4(9,000道尔顿)。此外,向受感染培养物中添加氯化锌会抑制病毒空斑形成,并干扰翻译后切割。
