A DNA TRANSFER VECTOR, A MICROORGANISM MODIFIED BY SAID VECTOR AND THE SYNTHESIS OF A EUCARYOTIC PROTEIN BY THE MODIFIED MICROORGANISM

摘要

A deoxyribonucleic acid (DNA) transfer vector is provided which comprises a nucleotide sequence coding for a eucaryotic protein joined to a procaryotic control fragment, the respective reading frames being in register, and the respective directions of transcription being the same. By connecting a eucaryotic gene to a gene for a protein normally compartmentalized or protected from intracellular degradation in some manner, the stability of a chimeric protein may by enhanced. A eucaryatic gene may be linked to a gene which has desirable genetic properties. In addition to the DNA transfer vector, the invention also provides a microorganism transformed by the transfer vector, a protein synthesised by such a microorganism, and a method of synthesising a protein.
