  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

    Different restriction enzymes acting on different recognition sites produce different DNA fragments. The term restriction enzyme originated from the studies of phage λ, a virus that infects bacteria, and the phenomenon of host-controlled restriction and modification of such bacterial phage or bacteriophage. [12]

    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

    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. 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]

  8. BglII - Wikipedia

    en.wikipedia.org/wiki/BglII

    BglII is a type II restriction endonuclease isolated from certain strains of Bacillus globigii. 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]

  9. HaeIII - Wikipedia

    en.wikipedia.org/wiki/HaeIII

    HaeIII is one of many restriction enzymes (endonucleases) a type of prokaryotic DNA that protects organisms from unknown, foreign DNA. [1] It is a restriction enzyme used in molecular biology laboratories. It was the third endonuclease to be isolated from the Haemophilus aegyptius bacteria.
