Uracil-DNA glycosylase causes 5-bromodeoxyuridine photosensitization in Escherichia coli K-12.

Journal of bacteriology - 1 Sept 1990

Yamamoto Y, Fujiwara Y

Abstract excerpt

An Escherichia coli uracil-DNA glycosylase-defective mutant (ung-1 thyA) was more resistant than its wild-type counterpart (ung+ thyA) to the killing effect of UV light when cultured in medium containing 5-bromouracil or 5-bromo-2'-deoxyuridine (BrdUrd). The phenotype of resistance to BrdUrd photosensitization and the uracil-DNA glycosylase deficiency appeared to be 100% cotransduced by P1 phage. During growth...
