Abstract

Summary: Mutations which allow tolerance to 5-bromo-2′-deoxyuridine (BUdR) in a thymidine (TdR)-requiring strain of have been examined. Differences in sensitivity to BUdR existed between isogenic strains harbouring the mutations. Those mutations originally isolated as BUdR-tolerant also bestowed tolerance to 5-bromouracil and vice versa. The strain exhibiting the greatest tolerance to BUdR maintained a normal rate of replication in the presence of BUdR whereas the parent strain did not, but the tolerant strain incorporated less analogue into DNA than the parent strain. The basis of the tolerance mutation appeared to lie at the point of uptake of the analogue into the cell as the tolerant mutant preferentially took up TdR over BUdR into whole cells. DNA polymerase activity measured did not distinguish between TdR and BUdR in either the parent or the mutant strain and although TdR kinase activity showed a preference for TdR over BUdR as a substrate, the extent of discrimination was similar in both strains.
