Abstract
Envelope glycoprotein of avian tumor virus is linked by disulfide bonds in a structure that we have designated VGP to stand for viral glycoprotein. VGP appears to contain one molecule of gp85 and one of gp37. Under nonreducing conditions, VGP is the only glycoprotein component that is stable in the presence of ionic detergent, although in the presence of nonionic detergent two or more VGPs are associated in discrete complexes. The disulfide bonds linking viral glycoprotein are formed before release of virus from infected cells.
摘要
禽肿瘤病毒的包膜糖蛋白通过二硫键连接成一种结构，我们将其命名为VGP，代表病毒糖蛋白。VGP似乎包含一个gp85分子和一个gp37分子。在非还原条件下，VGP是唯一在离子去污剂存在下稳定的糖蛋白成分，尽管在非离子去污剂存在下，两个或更多的VGP会形成离散的复合物。连接病毒糖蛋白的二硫键在病毒从感染细胞释放之前就已形成。
