METHOD OF PRODUCING BIOLOGICALLY ACTIVE VITAMIN K DEPENDENT PROTEINS BY RECOMBINANT METHODS |
摘要 |
The invention relates to commercially viable methods for producing biologically active vitamin K dependent proteins, particularly Factor IX. Factor IX is produced at a level of at least about 15 mg/L and is at least 25% biologically active. The method relies upon co-expression of one or more of paired basic amino acid converting enzyme (PACE), vitamin K dependent epoxide reductase (VKOR) and vitamin K dependent γ-glutamyl carboxylase (VKGC) at a preferred ratio so that the vitamin K dependent protein is efficiently produced and processed by a recombinant cell. |
