Abstract
A modified form of RNA polymerase from Bacillus subtilis selectively transcribes a cloned gene under early sporulation control. This RNA polymerase lacks sigma factor but contains a newly identified subunit of molecular weight 37,000, termed P37. P37 could be a regulatory protein that controls, at least in part, an early stage of spore development.
摘要
一种来自枯草芽孢杆菌的改良型RNA聚合酶能在芽孢形成早期控制下选择性转录一个克隆基因。这种RNA聚合酶缺乏σ因子，但含有一个新鉴定出的分子量为37,000的亚基，称为P37。P37可能是一种调控蛋白，至少部分控制着孢子发育的早期阶段。
