Abstract excerpt
The recA432 mutant allele was isolated (T. Kato and Y. Shinoura, Mol. Gen. Genet. 156:121-131, 1977) by virtue of its defect in cellular mutagenesis (Mut-) and its hypersensitivity to damage by UV irradiation (UVs), which were phenotypes expected for a recA mutant. However, we found that in a dif...
