'''FokI'''是一種存在於細菌''Flavobacterium okeanokoites''的type IIS限制酶，含有位於[[N端]]的[[DNA結合區塊]]（N-terminal DNA-binding domain），以及一個位於[[C端]]的非專一性DNA切割區塊<ref name="Durai 2005">{{cite journal en | author = Durai S, Mani M, Kandavelou K, Wu J, Porteus M, Chandrasegaran S | title = Zinc finger nucleases: custom-designed molecular scissors for genome engineering of plant and mammalian cells | journal = Nucleic Acids Res | volume = 33 | issue = 18 | pages = 5978-90 | year = 2005 | id = PMID 16251401 | url = http://nar.oxfordjournals.org/cgi/content/full/33/18/5978 | access-date = 2007-07-20 | archive-date = 2007-05-10 | archive-url = https://web.archive.org/web/20070510101730/http://nar.oxfordjournals.org/cgi/content/full/33/18/5978 | dead-url = no }}</ref>。當此酵素與[[DNA]]辨識並結合於5'-GGATG-3'[[识别位点]]時，將會把位於結合位置下游的9到13個[[核苷酸]]切除（不需特定序列）<ref name="Wah 1998">{{cite journal en| last=Wah| first= D.
