Abstract
A new relaxed mutant of Bacillus subtilis was isolated by screening Rifr clones for alterations in stringent control. The Rifr relaxed mutant which is described was found to contain a second-site mutation conferring a relaxed response to an energy source downshift and was partially relaxed after amino acid starvation. The new rel locus, called relG, was distinct from the two other known rel loci in B. subtilis, relA, and relC.
摘要
通过筛选利福平抗性（Rifr）克隆以寻找严紧控制方面的改变，分离出了一种新型的枯草芽孢杆菌松弛突变体。所描述的这种Rifr松弛突变体被发现含有一个第二位点突变，该突变赋予了对能量源下调的松弛反应，并且在氨基酸饥饿后部分松弛。这个新的rel位点被称为relG，它与枯草芽孢杆菌中另外两个已知的rel位点relA和relC不同。
