Resumen:
Un hospital universitario alemán ha desarrollado un nuevo enfoque para la producción de proteínas recombinantes que se emplea en la producción de reactivos para diagnósticos y tratamientos. Estas proteínas poseen una estructura plegable natural y la misma actividad biológica que las proteínas naturales. La tecnología permite la expresión de proteínas de interés en la superficie celular de bacterias, evitando la acumulación citoplasmática y periplasmática. El hospital busca licenciatarios del sector de biotecnología.

Production of recombinant protein on the cell surface of bacteria
Summary:
A German university hospital developed a novel approach for the production of recombinant proteins, that can be used for the production of reagents for diagnostics and therapy. These proteins have a natural folding structure and the same biological activity as a natural protein. Licensees from the biotech sector are sought.
Description:
The expression and production of recombinant proteins in bacteria, such as E. coli is a long standing and well known procedure. However, expression in bacterial systems is limited due to cytoplasmic accumulation of the protein of interest (POI). Even though, various attempts have been made to prevent the accumulation of the desired protein in inclusion bodies, there is to date no satisfactory solution available to overcome this problem.
The invention by a German university hospital enables the expression of POI on the cell surface of bacteria, thereby preventing the cytoplasmic and periplasmic accumulation. This is achieved by using an expression vector comprising the bacterial cell-surface protein FimH and the POI. Bacterial expression of this fusion protein leads to the localization of the protein on the cell surface. Thus, the fusion protein may be isolated from the surface of the bacterial cells or, alternatively, be isolated from the bacterial cell medium subsequent to secretion.
Thus, this novel strategy allows the production of recombinant proteins with a natural folding structure and the same biological activity as a natural protein. They can be used for the production of reagents that are suitable for diagnostics and therapy.
The The university offers licenses to industrial partners from the field of biotechnology, interested in implementing the new method.
