A PLASMID VECTOR USEFUL FOR THE EXPRESSION OF A FOREIGN DNA SEQUENCE

摘要

The present invention relates to expression vectors which permit the easy insertion of any desired DNA sequence into the vector, to recombinant organisms transformed with those vectors and to polypeptides produced by the transformed organisms. The vector includes a promoter, a transcription initiation site, a sequence of DNA encoding a portion of the N-terminus of the protein DELTA 7-pST, at least a first synthetic oligonucleotide linker, a transcription terminator and a selective marker, in that order and operatively linked to one another.
