  • System for release of proteins from microbe cells
    Patent number: 4948735
    Abstract: The invention concerns novel and useful mutant microbes which are capable of releasing substantial amounts of any of several periplasmic or recombinant proteins into the culture medium when carrying an expressed Kil gene. Though E. coli are exemplified, the invention is broadly applicable to the making of mutants of other microbes, for example, Salmonella, Klebsiella, and Rhizobium. A key feature of the invention is the use of a novel selection procedure employing a plasmid comprising the kil gene.
