restriction enzyme or restriction endonuclease,
an enzyme that cleaves the DNA strands of a species at a specific site which matches the DNA fragment of another species cut by the same enzyme, enabling segments of DNA from different sources to be joined in new combinations: »

A recently discovered class of enzymes called “restriction enzymes” has made gene insertions possible, but…has also created potential biohazards (Science News).
