Abstract
Abstract Living cells containing genetic material derived from recombinant DNA material and capable of expressing rennin, pre-prorennin and prorennin. The rennin, pre-prorennin and prorennin are derived from cells which are themselves or have had parents thereof treated by recombinant DNA methods to allow production of the desired enzymatic proteins during growth in culture.
