DNA fragments, containing a lactic acid bacterium-specific regulator region for the expression of genes coding for normally heterologous proteins

摘要

The invention relates to lactic acid bacteria which comprise recombinant plasmids containing a lactic acid bacterium-specific regulator region suitable for the expression of normally heterogenous proteins like prochymosin, and the gene in question coding for the relevant protein. The (heterologous) proteins are produced by means of a system which as such is accepted in the food-stuff industry.
