Specific mutator effects of ung (uracil-DNA glycosylase) mutations in Escherichia coli.
Studies of trpA reversions revealed that G:C leads to A:T transitions were stimulated about 30-fold in E. coli ung mutants, whereas other base substitutions were not affected. A dUTPase (dut) mutation, which increases the incorporation of uracil into DNA in place of thymine, had no significant effec...
