We have isolated mutations that appear to inactivate the gene (lacA) encoding an endogenous beta-galactosidase activity in Bacillus subtilis and in a closely linked negative regulatory element (lacR). Both genes map to the hisA-thrA region. The lacA mutations may help to avoid some of the problems arising from the use of the Escherichia coli lacZ gene as a reporter gene in B. subtilis.
我们已经分离出一些突变,这些突变似乎使编码枯草芽孢杆菌内源性β-半乳糖苷酶活性的基因(lacA)以及一个紧密连锁的负调控元件(lacR)失活。这两个基因都定位于hisA-thrA区域。lacA突变可能有助于避免在枯草芽孢杆菌中使用大肠杆菌lacZ基因作为报告基因所产生的一些问题。
