Zusammenfassung:There are described: a bifunctional vector for the cloning of a DNA sequence which codes for a heterologous protein; recombinant plasmids expressed in Bacillus and obtained by cloning the heterologous DNA sequence in the vector under the control of a strong promotor which directs the transcription of a polycystronic mRNA; and a method for the preparation of the heterologous protein which comprises the growth, in a suitable culture medium, of Bacillus cells transformed by the recombinant plasmids. The proteins thus obtained are usable in the therapeutic and diagnostic fields. Examples of the proteins are the mature subunits of the pertussis toxin.
