Escherichia coli K-12 clones that overproduce dam methylase are hypermutable.

G E Herman, P Modrich.   

Abstract

A strain of Escherichia coli K-12 that overproduces dam methylase 50-fold was found to be hypermutable, and mutations which resulted in loss of excess methylase activity restored mutation frequencies to wild-type levels. These results are consistent with involvement of this deoxyribonucleic acid methylase in mismatch correction.
