Structures of the type I DNA restriction enzymes. [PDF]
The article by Liu et al. (1) on the structure of type I DNA restriction and modification enzymes purports to significantly advance our understanding of these enzymes and proposes a model for their operation. While the partial structure of one of these enzymes is interesting and defines the interface between some of the subunits, the article contains ...

Restriction enzyme digestion of hemimethylated DNA [PDF]
Hemimethylated duplex DNA of the bacteriophage phi X 174 was synthesized using primed repair synthesis is in vitro with E. coli DNA polymerase I followed by ligation to produce the covalently closed circular duplex (RFI). Single-stranded phi X DNA was used as a template, a synthetic oligonucleotide as primer and 5-methyldeoxycytidine-5'-triphosphate ...

In vitro Type II Restriction of Bacteriophage DNA With Modified Pyrimidines
To counteract host-encoded restriction systems, bacteriophages (phages) incorporate modified bases in their genomes. For example, phages carry in their genomes modified pyrimidines such as 5-hydroxymethyl-cytosine (5hmC) in T4gt deficient in α- and β ...
