  • Method for producing the SSPI restriction endonuclease and methylase
    Patent number: 5516678
    Abstract: The present invention is directed to a method for cloning and producing the SspI restriction endonuclease by 1) introducing the restriction endonuclease gene from Sphaerotilus species into a host whereby the restriction gene is expressed; 2) fermenting the host which contains the vector encoding and expressing the SspI restriction endonuclease, and 3) purifying the SspI restriction endonuclease from the fermented host which contains the vector encoding and expressing the SspI restriction endonuclease activity.
    Type: Grant
    Filed: October 6, 1994
    Date of Patent: May 14, 1996
    Assignee: New England Biolabs, Inc.
    Inventors: Jack S. Benner, Linda H. Coe
  • Isolated DNA encoding the NotI restriction endonuclease and related methods for producing the same
    Patent number: 5371006
    Abstract: 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.
    Type: Grant
    Filed: January 11, 1993
    Date of Patent: December 6, 1994
    Assignee: New England Biolabs, Inc.
    Inventors: Richard D. Morgan, Jack S. Benner, Toby E. Claus
  • Method for producing the Hpa I restriction endonuclease and methylase
    Patent number: 5298404
    Abstract: The present invention is directed to a method for cloning and producing the Hpa I restriction endonuclease by 1) introducing the restriction endonuclease gene from Haemophilus parainfluenzae into a host whereby the restriction gene is expressed; 2) fermenting the host which contains the vector encoding and expressing the Hpa I restriction endonuclease, and 3) purifying the Hpa I restriction endonuclease from the fermented host which contains the vector encoding and expressing the Hpa I restriction endonuclease activity.
    Type: Grant
    Filed: October 13, 1989
    Date of Patent: March 29, 1994
    Assignee: New England Biolabs, Inc.
    Inventors: Jack S. Benner, Phyllis Rees
  • Method for producing the Nde I restriction endonuclease and methylase
    Patent number: 5139942
    Abstract: The present invention is directed to a method for cloning and producing the Nde I restriction endonuclease by 1) introducing the restriction endonuclease gene from Neisseria denitrificans into a host whereby the restriction gene is expressed; 2) fermenting the host which contains the vector encoding and expressing the Nde I restriction endonuclease, and 3) purifying the Nde I restriction endonuclease from the fermented host which contains the vector encoding and expressing the Nde I restriction endonuclease activity.
