Abstract
The W-reactivation system of Bacillus subtilis repairs pyrimidine dimers in bacteriophage DNA. This inducible repair system can be activated by treatment of the bacteria with UV, alkylating agents, cross-linking agents and gamma radiation. However, bacteriophage treated with agents other than those that cause pyrimidine dimers were not repaired by this unique form of W-reactivation. In contrast, the W-reactivation system of Escherichia coli repairs a variety of damages in the bacteriophage DNA.
摘要
枯草芽孢杆菌的W-复活系统可修复噬菌体DNA中的嘧啶二聚体。这种可诱导的修复系统可以通过用紫外线、烷化剂、交联剂和γ辐射处理细菌来激活。然而，用除导致嘧啶二聚体的试剂以外的其他试剂处理的噬菌体不能通过这种独特形式的W-复活得到修复。相比之下，大肠杆菌的W-复活系统可修复噬菌体DNA中的多种损伤。
