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.
