Patents by Inventor Edith Cerbeleaud

Edith Cerbeleaud has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Isolated DNA encoding a nitrilase polypeptide, hosts containing, and expression thereof optionally assisted by a E. coli GroE chaperone polypeptide
    Patent number: 5635391
    Abstract: The present invention relates to novel polypeptides having a nitrilase activity and to the genetic tools for producing them, namely:the DNA sequence coding for a polypeptide having a nitrilase activity and capable of hydrolyzing nitriles to carboxylates,an analog of this sequence resulting from the degeneracy of the genetic code,a DNA sequence hybridizing with one of these sequences or a fragment thereof and coding for a polypeptide having a nitrilase activity,expression cassettes and microorganisms enabling them to be obtained. Application: enzymatic conversion of nitriles to carboxylates.
    Type: Grant
    Filed: June 5, 1995
    Date of Patent: June 3, 1997
    Assignee: Rhone-Poulenc Chimie
    Inventors: Dominique Petre, Edith Cerbeleaud, Sophie Levy-Schil, Joel Crouzet
