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. WebA restriction fragment is a DNA fragment resulting from the cutting of a DNA strand by a restriction enzyme (restriction endonucleases), a process called restriction.
