Left-and right-border repeats, which surround the T-region, contain two conserved regions
separated by 5 bp that are not conserved. At the onset of T-DNA processing virD-encoded …

Introduction 2.1. Genetic organization and nomenclature 2.2. Families of type I restriction
enzymes 2.3. DNA methylation and cleavage 3. DNA translocation and molecular motor …

The hsd locus (host specificity of DNA) was identified in the Neisseria gonorrhoeae genome.
The DNA fragment encoding this locus produced an active restriction and modification (R/M) …

In previous work on DNA‐(cytosine‐C5)‐methyltransferases (C5‐MTases), domains had
been identified which are responsible for the sequence specificity of the different enzymes …

Helicobacter pylori is a carcinogenic bacterium that is responsible for 5.5% of all human
gastric cancers. H. pylori codes for an unusually large number of restriction–modification (R …

This study characterized several mutations of the bacteriophage P1 mod gene. This gene
codes for the subunit of the EcoP1 restriction enzyme that is responsible for DNA sequence …

A vector was designed to allow predetermined and precise fusion between two cloned
genes by constructing a cassette with two unique class-IIS restriction sites, 5′—ACCTGC …

To explore new approaches to enzyme engineering, intra-domain chimeras of two
aminoacyltRNA synthetases were constructed. Connections were made within the …

Using a plasmid transformation method and the RM search computer program, four type I
restriction enzymes with new recognition sites and two isoschizomers (EcoBI and Eco377I) …

Abstract The BcgI and other BcgI-like restriction endonucleases differ from other types of
endonucleases in that they cleave double-stranded DNA on both sides of their recognition …
