Abstract
The present invention is directed to a method for cloning and producing the FnuDI restriction endonuclease by (1) introducing the restriction endonuclease gene from F. nucleatum D into a host whereby the restriction gene is expressed; (2) fermenting the host which contains the vector encoding and expressing the FnuDI restriction endonuclease, and (3) purifying the FnuDI restriction endonuclease from the fermented host which contains the vector encoding and expressing the FnuDI restriction endonuclease activity.
