Abstract

Herpes simplex virus-induced DNA polymerase purified by published methods was found to be contaminated with many others proteins, including virus structural proteins. Thus, DEAE-cellulose and phosphocellulose chromatography were used in combination with affinity chromatography to purify DNA polymerase from herpes simplex virus type 1- and type 2-infected cells. The purified enzyme retained unique features of the herpesvirus-induced DNA polymerase, including a requirement for high salt concentrations for maximal activity, a sensitivity to low phosphonoacetate concentrations, and the capacity to be neutralized by rabbit antiserum to herpesvirus-infected cells. By polyacrylamide gel electrophoresis, the purified DNA polymerase was associated with a virus-induced polypeptide of about 150,000 molecular weight.

摘要

通过已发表方法纯化的单纯疱疹病毒诱导的DNA聚合酶被发现污染有许多其他蛋白质,包括病毒结构蛋白。因此,结合离子交换纤维素和磷酸纤维素色谱法与亲和色谱法,从1型和2型单纯疱疹病毒感染的细胞中纯化DNA聚合酶。纯化后的酶保留了疱疹病毒诱导的DNA聚合酶的独特特性,包括最大活性需要高盐浓度、对低浓度膦酰乙酸敏感以及能被兔抗疱疹病毒感染细胞血清中和。通过聚丙烯酰胺凝胶电泳,纯化的DNA聚合酶与一种分子量约为150,000的病毒诱导多肽相关。
