Method for cloning and producing the BglII restriction endonuclease and modification methylase

摘要

The present invention is directed to a method for cloning and producing the BglII endonuclease by: 1) introducing the restriction endonuclease gene from Bacillus globigii into a host whereby the restriction gene is expressed; 2) fermenting the host which contains the plasmid encoding and expressing the BglII restriction endonuclease activity; and 3) purifying the BglII restriction endonuclease from the fermented host which contains the plasmid encoding and expressing the BglII restriction endonuclease.
