This article contains a list of the most studied restriction enzymes whose names start with E to F inclusive. It contains approximately 110 enzymes.

The following information is given:

Enzyme: Accepted name of the molecule, according to the internationally adopted nomenclature^[1]^[2], and bibliographical references. (Further reading: see the section "Nomenclature" in the article "Restriction enzyme".)
PDB code: Code used to identify the structure of a protein in the PDB database of protein structures. The 3D atomic structure of a protein provides highly valuable information to understand the intimate details of its mechanism of action^[3]^[4].
Source: Organism that naturally produces the enzyme.
Recognition sequence: Sequence of DNA recognized by the enzyme and to which it specifically binds.
Cut: Cutting site and DNA products of the cut. The recognition sequence and the cutting site usually match, but sometimes the cutting site can be dozens of nucleotides away from the recognition site^[5]^[6].
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. Neoschizomers are shown in bold and green color font (e.g.: BamHI). When "None on date" is indicated, that means that there were no registered isoschizomers in the databases on that date with a clearly defined cutting site. Isoschizomers indicated in white font and grey background correspond to enzymes not listed in the current lists:
