Open the CIPO recordAbstract From the Canadian patent
The present invention is directed to a novel dipeptidylaminopeptidase isolated from the cellular slime mold, Dictyostelium discodeum. The novel DAP enzyme dDAP, displays an activity which is somewhat similar to both DAP- I and DAP-III but is highly distinctive from these enzymes in physical and other enzymatic characteristics. The invention is also directed to methods for using the dDAP enzyme to remove dipeptides from the N-terminus of recombinantly produced precursor proteins or peptides. In addition, the invention relates to methods for isolating and purifying the dDAP enzyme from cultures of D. discoedeum.

Why it's free to use
- Filed September 29, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 29, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 29, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
