  2. Restriction modification system - Wikipedia

    en.wikipedia.org/wiki/Restriction_modification...

    The restriction modification system (RM system) is found in bacteria and archaea, and provides a defense against foreign DNA, such as that borne by bacteriophages.. Bacteria have restriction enzymes, also called restriction endonucleases, which cleave double-stranded DNA at specific points into fragments, which are then degraded further by other endonucleases.

  3. Restriction enzyme - Wikipedia

    en.wikipedia.org/wiki/Restriction_enzyme

    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.

  4. List of restriction enzyme cutting sites - Wikipedia

    en.wikipedia.org/wiki/List_of_restriction_enzyme...

    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.

  5. List of restriction enzyme cutting sites: A - Wikipedia

    en.wikipedia.org/wiki/List_of_restriction_enzyme...

    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 ...

  6. EcoRI - Wikipedia

    en.wikipedia.org/wiki/EcoRI

    EcoRI is an example of type II restriction enzymes which now has more the 300 enzymes with more than 200 different sequence-specificities, which has transformed molecular biology and medicine. [ 3 ] EcoRI, discovered in 1970, was isolated by PhD student Robert Yoshimori who investigated clinical E. coli isolates that contained restriction ...

  7. Endonuclease - Wikipedia

    en.wikipedia.org/wiki/Endonuclease

    Restriction endonucleases (restriction enzymes) are divided into three categories, Type I, Type II, and Type III, according to their mechanism of action. These enzymes are often used in genetic engineering to make recombinant DNA for introduction into bacterial, plant, or animal cells, as well as in synthetic biology . [ 5 ]

  8. R.EcoRII - Wikipedia

    en.wikipedia.org/wiki/R.EcoRII

    Restriction endonuclease (REase) EcoRII (pronounced "eco R two") is an enzyme of restriction modification system (RM) naturally found in Escherichia coli, a Gram-negative bacteria. Its molecular mass is 45.2 kDa, being composed of 402 amino acids. [1]

  9. BglII - Wikipedia

    en.wikipedia.org/wiki/BglII

    The principal function of restriction enzymes is the protection of the host genome against foreign DNA, but they may also have some involvement in recombination and transposition. [1] Like most type II restriction enzymes, BglII consists of two identical subunits that form a homodimer around the DNA double helix.
