ABSTRACT:
This invention provides a DNA sequence coding for a cleavage site which is specifically cleaved by blood coagulation Factor Xa, a vector containing such a sequence, and a host organism transformed with such a vector. Preferably, in the vector, the Factor Xa cleavage site coding sequence is fused at one end to a product and at its other end to an ATG codon or a sequence coding for at least part of a host protein.
This invention also provides a process, for the production of a desired protein or peptide product in native form, comprising:
