Interactions between Bacillus subtilis early spore coat morphogenetic proteins.
When challenged by stresses such as starvation, the soil bacterium Bacillus subtilis produces an endospore surrounded by a proteinaceous coat composed of >70 proteins that are organized into three main layers: an amorphous undercoat, lightly staining lamellar inner coat and electron-dense outer coat. This coat protects the spore against a variety of chemicals or lysozyme. Mutual interactions of...
متن کاملBacillus subtilis spore coat.
In response to starvation, bacilli and clostridia undergo a specialized program of development that results in the production of a highly resistant dormant cell type known as the spore. A proteinacious shell, called the coat, encases the spore and plays a major role in spore survival. The coat is composed of over 25 polypeptide species, organized into several morphologically distinct layers. Th...
متن کاملA versatile nano display platform from bacterial spore coat proteins
Dormant bacterial spores are encased in a thick protein shell, the 'coat', which contains ∼70 different proteins. The coat protects the spore from environmental insults, and is among the most durable static structures in biology. Owing to extensive cross-linking among coat proteins, this structure has been recalcitrant to detailed biochemical analysis, so molecular details of how it assembles a...
متن کاملBacillus subtilis spore display of recombinant proteins using a coat-associated enzyme as carrier
Display of proteins like 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 5 impact of increased animal production. To deliver their full potential in the gut, feed enzymes must survive the ha...
متن کاملRole of spore coat proteins in the resistance of Bacillus subtilis spores to Caenorhabditis elegans predation.
Bacterial spores are resistant to a wide range of chemical and physical insults that are normally lethal for the vegetative form of the bacterium. While the integrity of the protein coat of the spore is crucial for spore survival in vitro, far less is known about how the coat provides protection in vivo against predation by ecologically relevant hosts. In particular, assays had characterized th...
