Although many different methods are used for the identification of methylated heterocyclic bases in DNA not all of them possess the ability to discriminate N4-methylcytosine (m4C) and 5-methylcytosine (m5C). Therefore, some of the methods need additional reexamination.

Summary The modification methylase from Escherichia coli strain B, Eco B, introduces two methyl groups into one SV40 DNA molecule. The only base methylated has been identified as N6-methyladenine. Digestion of the methylated SV40 DNA with two restriction endonucleases, one from Hemophilus influenzae , Hind III, and another from Hemophilus ...

A DNA-modification methylase from Bacillus stearothermophilus V.
The Biochemical journal, 1989A type II modification methylase (M BstVI) was partially purified from the thermophilic bacterium Bacillus stearothermophilus V. The methylase catalyses the transfer of methyl groups from S-adenosyl-L-methionine to unmodified double-stranded DNA. The product of methylation was identified by paper chromatography as N6-methyladenine.

The paper describes a technique for the detection of new strains producing enzymes which mediate DNA modification and restriction, and isoschizomers and isomethylomers of the known restriction endonucleases and methylases. Three Bacillus subtilis strains whose DNA carries a BamH1 modification have been found.
