Abstract
Bacteriophage T4 gene 33 protein (gp33), which is required for viral late transcription, has been overproduced. The purified gp33 binds to RNA polymerase core from uninfected or T4-infected Escherichia coli, but the major E. coli transcription initiation factor, sigma 70, competed effectively for this binding.
摘要
噬菌体T4基因33蛋白（gp33）是病毒晚期转录所必需的，现已大量产生。纯化后的gp33可与未感染或T4感染的大肠杆菌的RNA聚合酶核心结合，但主要的大肠杆菌转录起始因子σ70能有效地竞争这种结合。
