Open the CIPO recordAbstract From the Canadian patent
The use of enzymes which catalyze the production of starter and extender units for polyketides is described. These enzymes may be used to enhance the yield of polyketides that are natively produced or polyketides that are rationally designed. By using these techniques, the synthesis of a complete polyketide has been achieved in E. coli. This achievement permits a host organism with desirable characteristics to be used in the production of such polyketides and to assess the results of gene shuffling.

Why it's free to use
- Filed October 13, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 13, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 13, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
