Following UV irradiation of Bacillus subtilis there is a coordinate induction of: 1) a new protein, 2) a W-reactivation system, 3) a DNA modification system, and 4) prophages. These functions are induced following UV irradiation of repair proficient bacteria and mutants deficient in excision repair (UVR-1) and DNA polymerase I activity (polA5). However, they are not induced, or are impaired in their ability to be induced in bacteria containing the recA1 and the recG13 mutations. This inducible system is compared to the SOS system observed in E. coli.
枯草芽孢杆菌经紫外线照射后，会协同诱导出以下几种情况：1）一种新蛋白质；2）一种W-复活系统；3）一种DNA修饰系统；4）原噬菌体。这些功能在修复能力正常的细菌以及切除修复缺陷型（UVR-1）和DNA聚合酶I活性缺陷型（polA5）的突变体经紫外线照射后都会被诱导产生。然而，在含有recA1和recG13突变的细菌中，这些功能不会被诱导产生，或者诱导能力受损。这种可诱导系统与在大肠杆菌中观察到的SOS系统进行了比较。
