Mutation in Escherichia coli under starvation conditions: a new pathway leading to small deletions in strains defective in mismatch correction

Strains of Escherichia coli carrying the mutY mutation lack a mismatch correction glycosylase that removes adenines from various mismatch situations. In growing bacteria, 8‐oxoguanine–adenine mispairs persist and can give rise to G→T transversions during subsequent replication cycles. We now show th...
