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 کاملThe Direct Interaction between Two Morphogenetic Proteins Is Essential for Spore Coat Formation in Bacillus subtilis
In Bacillus subtilis the protective layers that surround the mature spore are formed by over seventy different proteins. Some of those proteins have a regulatory role on the assembly of other coat proteins and are referred to as morphogenetic factors. CotE is a major morphogenetic factor, known to form a ring around the forming spore and organize the deposition of the outer surface layers. CotH...
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 کاملPhysical interaction between coat morphogenetic proteins SpoVID and CotE is necessary for spore encasement in Bacillus subtilis.
Endospore formation by Bacillus subtilis is a complex and dynamic process. One of the major challenges of sporulation is the assembly of a protective, multilayered, proteinaceous spore coat, composed of at least 70 different proteins. Spore coat formation can be divided into two distinct stages. The first is the recruitment of proteins to the spore surface, dependent on the morphogenetic protei...
