  • Bovine dipeptidylaminopeptidase 1
    Patent number: 6027911
    Abstract: The present invention provides the cDNA sequence encoding bovine dipeptidylaminopeptidase 1. The invention demonstrates that bovine DAP 1 coded by a single cDNA. The mature protein is derived from a single polypeptide consisting of a signal peptide, and a major polypeptide which is processed to generate the a subunit, b subunit and g subunit.
    Type: Grant
    Filed: April 3, 1998
    Date of Patent: February 22, 2000
    Assignee: Eli Lilly and Company
