    摘要: The present invention relates to modified cDNA sequences coding for human Factor X and their derivatives with improved stability and modified activation sequences, recombinant expression vectors containing such cDNA sequences, and host cells transformed with such recombinant expression vectors. The invention also relates to recombinant factor X polypeptides and derivatives which have biological activities of the unmodified wild type protein but with improved stability and processes for the manufacture of such recombinant proteins and their derivatives. The invention also covers a transfer vector for use in human gene therapy, which comprises such modified DNA.
