Abstract: We constructed an ada deletion by gene replacement in a recD1014 strain of Escherichia coli. Characterization of a delta ada-25 recD+ strain revealed the presence of a second DNA methyltransferase activity in E. coli K-12 which transfers a methyl group from methylated DNA to a protein with a molecular weight of 18,000 to 20,000.
