Surface display of recombinant proteins on Bacillus subtilis spores.
We developed a novel surface display system based on the use of bacterial spores. A protein of the Bacillus subtilis spore coat, CotB, was found to be located on the spore surface and used as fusion partner to express the 459-amino-acid C-terminal fragment of the tetanus toxin (TTFC). Western, dot blot and fluorescent-activated cell sorting analyses were used to monitor TTFC surface expression ...
متن کاملSurface display of recombinant proteins on Bacillus thuringiensis spores.
The insecticidal protoxin from Bacillus thuringiensis has been shown to be a major component of the spore coat. We have developed a novel surface display system using B. thuringiensis spores in which the N-terminal portion of the protoxin is replaced with a heterologous protein. The expression vector with a sporulation-specific promoter was successfully used to display green fluorescent protein...
متن کاملDisplay of recombinant proteins on Bacillus subtilis spores, using a coat-associated enzyme as the carrier.
The display of proteins such as feed enzymes at the surface of bacterial spore systems has a great potential use for animal feed. Feed enzymes increase the digestibility of nutrients, leading to greater efficiency in the manufacturing of animal products and minimizing the environmental impact of increased animal production. To deliver their full potential in the gut, feed enzymes must survive t...
متن کاملExpression and display of UreA of Helicobacter acinonychis on the surface of Bacillus subtilis spores
BACKGROUND The bacterial endospore (spore) has recently been proposed as a new surface display system. Antigens and enzymes have been successfully exposed on the surface layers of the Bacillus subtilis spore, but only in a few cases the efficiency of expression and the effective surface display and have been determined. We used this heterologous expression system to produce the A subunit of the...
متن کاملSurface display of OmpC of Salmonella serovar Pullorum on Bacillus subtilis spores
Salmonellosis is a major public health problem throughout the world. Thus, there is a huge need for diversified control strategies for Salmonella infections. In this work, we have assessed the potential use of Bacillus subtilis (B. subtilis) spores for the expression of a major protective antigen of Salmonella serovar Pullorum, OmpC. The expression of OmpC on the surface of spores was determine...
