Molecular and General Genetics MGG Aims and scope Submit manuscript

Summary

The genes responsible for DNA adenine methylation (dam) and DNA cytosine methylation (dcm) have been mapped on the E. coli K-12 genetic map. The dam gene is situated at min 65 and the gene order cysG-(trpS, dam)-aro B inferred. The dcm gene is located at min 37.5 and the gene order is supD-dcm-flaA1. In F′ merodiploids, the dam and dcm alleles are recessive.
