Chapter
A Nomenclature for Restriction Enzymes, DNA Methyltransferases, Homing Endonucleases, and Their Genes
There are three main groups of restriction endonucleases (REases) called Types I, II, and III (1,2). Since 1973, REases and DNA methyltransferases (MTases) have been named based on an original suggestion by Sm...

Chapter
Structure and Function of Type IIE Restriction Endonucleases — or: From a Plasmid That Restricts Phage Replication to A New Molecular DNA Recognition Mechanism
Restriction endonucleases (REases) and DNA methyltransferases (MTases) are encoded by chromosomal, plasmid, or viral genes. In eubacteria as well as in archaea, they often form biologically active DNA restrict...

Diagnostic value of human cytomegalovirus DNA PCR regarding different clinical specimens
In transplant recipients, a positive HCMV PCR in PBLs is a sign of the possible development of HCMV disease which should be confirmed by further diagnostic approaches. However, detection of HCMV DNA in the CSF...

Avoidance of DNA methylation
Theocr + gene of bacterial virus T7 codes for the first protein recognized to inhibit a specific group of DNA methylases. The recognition sequences of several other DNA methylases, not susceptible...

Protection of foreign DNA against host-controlled restriction in bacterial cells
Foreign F′lac plasmid DNA which is introduced into potentially restricting E. coli recipient cells can be protected from restriction by preinfecting the recipient cells with UV-inactivated T3 or T7 bacteriophages...

Host-dependent modification of bacteriophage T7 and SAMase-negative T3 derivatives affecting their adsorption ability
When passaging phage T7 and SAMase-negative T3 mutants betweenE. coli strains with identical (EcoB) or without (EcoO) DNA host specificity, phenotypically a host-controlled modification and restriction is observe...

Active protection by bacteriophages T3 and T7 againstE. coli B-and K-specific restriction of their DNA
The bacteriophages T3 and T7 are not modified and restricted byE. coli strains with different host specificity (E. coli B, K, O) in vivo. The phages code for a gene product with the ability toovercomeclassicalres...
