A PLASMID FOR EXPRESSING MODIFIED RECOMBINANT PROTEINS IN A BACTERIAL SYSTEM

摘要

The present invention provides a plasmid containing a promoter sequence, a nucleotide sequence encoding an exogenous protein, and a nucleotide sequence encoding an enzyme capable of modifying the exogenous protein. In a specific embodiment of the invention the encoded exogenous protein is human beta -casein and the encoded enzyme is a human kinase capable of phosphorylating recombinant beta -casein in a bacterial system.
