Abstract
Cryoelectron microscopy of Mouse mammary tumor virus, a Betaretrovirus, provided information about glycoprotein structure and core formation. The virions showed the broad range of diameters typical of retroviruses. Betaretroviruses assemble cytoplasmically, so the broad size range cannot reflect the use of the plasma membrane as a platform for assembly.
摘要
对一种β逆转录病毒——小鼠乳腺肿瘤病毒进行的冷冻电子显微镜观察，提供了有关糖蛋白结构和核心形成的信息。这些病毒粒子呈现出逆转录病毒典型的广泛直径范围。β逆转录病毒在细胞质中组装，因此这种广泛的大小范围并不能反映出将质膜用作组装平台的情况。
