This article continues the series of Surveys and Summaries on restriction endonucleases
(REases) begun this year in Nucleic Acids Research. Here we discuss 'Type II'REases, the …

Type II restriction endonucleases are components of restriction modification systems that
protect bacteria and archaea against invading foreign DNA. Most are homodimeric or …

Type I restriction enzymes (REases) are large pentameric proteins with separate restriction
(R), methylation (M) and DNA sequence-recognition (S) subunits. They were the first …

More than 3000 type II restriction endonucleases have been discovered. They recognize
short, usually palindromic, sequences of 4–8 bp and, in the presence of Mg2+, cleave the …

Type IIs restriction endonucleases recognize asymmetric DNA sequences and cleave both
DNA strands at fixed positions, typically several base pairs away from the recognition site …

Restriction endonucleases are enzymes which recognize short DNA sequences and cleave
the DNA in both strands. Depending on the enzymological properties different types are …

Abstract In the early 1950's,'host-controlled variation in bacterial viruses' was reported as a
non-hereditary phenomenon: one cycle of viral growth on certain bacterial hosts affected the …

Restriction endonucleases have become a fundamental tool of molecular biology with many
commercial vendors and extensive product lines. While a significant amount has been …

Structures of two restriction endonucleases, BamHI and PvuII, were reported in the past
year. This doubles the number of restriction endonuclease structures now known from two to …
