Name of Restriction Enzyme: Accepted name of the molecule, according to the internationally adopted nomenclature, [1] [2] and bibliographical references. Note: When alphabetizing, enzymes are first ordered alphabetically by the acronyms (everything before the roman numeral); then enzymes of a given acronym are ordered alphabetically by the ...
A restriction enzyme or restriction endonuclease is a special type of biological macromolecule that functions as part of the "immune system" in bacteria.One special kind of restriction enzymes is the class of "homing endonucleases", these being present in all three domains of life, although their function seems to be very different from one domain to another.
Isoschizomers and neoschizomers: An isoschizomer is an enzyme that recognizes the same sequence as another. A neoschizomer is a special type of isoschizomer that recognizes the same sequence as another, but cuts in a different manner. A maximum number of 8-10 most common isoschizomers are indicated for every enzyme but there may be many more.
A restriction enzyme, restriction endonuclease, REase, ENase or restrictase is an enzyme that cleaves DNA into fragments at or near specific recognition sites within molecules known as restriction sites. [1] [2] [3] Restriction enzymes are one class of the broader endonuclease group of enzymes.

REBASE contains an extensive set of references, sites of recognition and cleavage, sequences and structures. It also contains information on the commercial availability of each enzyme. REBASE is one of the longest running biological databases having its roots in a collection of restriction enzymes maintained by Richard J. Roberts since before ...
Several databases exist for restriction sites and enzymes, of which the largest noncommercial database is REBASE. [5] [6] Recently, it has been shown that statistically significant nullomers (i.e. short absent motifs which are highly expected to exist) in virus genomes are restriction sites indicating that viruses have probably got rid of these motifs to facilitate invasion of bacterial hosts.
