Saturation of DNA mismatch repair and error catastrophe by a base analogue in Escherichia coli.

Deoxyribosyl-dihydropyrimido[4,5-c][1,2]oxazin-7-one (dP) is a potent mutagenic deoxycytidine-derived base analogue capable of pairing with both A and G, thereby causing G. C --> A. T and A. T --> G. C transition mutations. We have found that the Escherichia coli DNA mismatch-repair system can...
