WebEcoRI (pronounced "eco R one") is a restriction endonuclease enzyme isolated from species E. coli. It is a restriction enzyme that cleaves DNA double helices into fragments at specific sites, and is also a part of the restriction modification system. The Eco part of the enzyme's name originates from the species from which it was isolated - "E" denotes … WebA maximum number of 8–10 most common isoschizomers are indicated for every enzyme but there may be many more. Neoschizomers are shown in bold and green color font (e.g.: BamHI ). When "None as of [date]" is indicated, that means that there were no registered isoschizomers in the databases on that date with a clearly defined cutting site.
