PCT No. PCT/DE94/01394 Sec. 371 Date Jul. 18, 1996 Sec. 102(e) Date Jul. 18, 1996 PCT Filed Nov. 21, 1994 PCT Pub. No. WO95/20048 PCT Pub. Date Jul. 27, 1995The invention relates to a process for producing outer membrane proteins of gram-negative bacteria by gram-positive host cells. To this end, a gene structure containing a gene coded for an outer membrane protein is constructed; in front of this gene there is a pro-gene sequence which codes for a propeptide of an export protein of a gram-positive bacterium. In front of the pro-gene sequence there is a pre-gene sequence which codes for a signal peptide of an export protein of a gram-positive bacterium. After the cloning of a gene structure thus constructed into a vector and transformation into a gram-positive bacterium, the outer membrane protein is expressed with a signal peptide and propeptide, transported through the membrane of the gram-positive host cell and released into the test of the culture.
