| 摘要 |
The present invention is directed to a method for cloning and producing the NotI restriction endonuclease by 1) introducing the restriction endonuclease gene from Nocardia otitidis-caviarum into a host whereby the restriction gene is expressed; 2) fermenting the host which contains the plasmid encoding and expressing the NotI restriction endonuclease activity, and 3) purifying the NotI restriction endonuclease from the fermented host which contains the plasmid encoding and expressing the NotI restriction endonuclease activity. <IMAGE> |
