Open the CIPO recordAbstract From the Canadian patent
The present invention relates to a method for the production of collagen-like compounds containing hydroxylated proline residues. Of specific interest is the production of recombinant collagen-like compounds in which hydroxylation of proline residues is achieved by a prolyl hydroxylase from a fungus preferably a yeast, in particular Hansenula polymorpha. Also the invention concerns a method for controlling the hydroxylation of proline residues by such a prolyl hydroxylase characterised by the addition of collagen-like oligopeptides, such as gelatine hydrolysate in particular gelatone or peptone.

Why it's free to use
- Filed July 11, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 11, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 11, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
