PCT No. PCT/EP91/00308 Sec. 371 Date Sep. 30, 1992 Sec. 102(e) Date Sep. 30, 1992 PCT Filed Feb. 19, 1991 PCT Pub. No. WO91/13155 PCT Pub. Date Sep. 5, 1991.The invention concerns a carrier-bound recombinant protein obtainable by expression of a fusion protein gene in gram-negative bacteria which codes for at least one hydrophobic non-lytically active protein domain capable of membrane integration as well as the recombinant protein and of a gene which codes for a lytically active membrane protein from bacteriophages or a lytically active toxin release gene or lytically active partial sequences thereof and isolation of the carrier-bound recombinant protein from the culture broth. The recombinant protein is thereby firmly incorporated into the cell wall complex of gram-negative bacteria via a target sequence. Furthermore the invention concerns a recombinant DNA for the production of the protein, the production process as well as the use of carrier-bound recombinant proteins according to the present invention for immunization and as vaccines.
