Bacillus 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 کاملSPIF regulates spore coat protein synthesis
Spore coat protein synthesis in submerged pseudoplasmodia of Dictyostelium discoideum is dependent on the presence of a low relative molecular mass extracellular factor, SPIF, the activity of which can be mimicked by methionine. In vitro translation and northern blot analysis revealed that the level of spore coat protein mRNA in pseudoplasmodia incubated in the absence of methionine is little d...
متن کاملProteomic characterization of spore coat protein mutants of Bacillus subtilis
Spore coat proteins play an important role in maintaining spore structure as well as the resistive capacity of the spores. Spore morphogenetic proteins are responsible for layering the proteinaceous layers during spore morphogenesis. Previous studies have analyzed the dependence of certain coat proteins on the well-known morphogenetic proteins such as SpoIVA, CotE, CotH etc. Yet many coat prote...
متن کاملInvolvement of the spore coat in germination of Bacillus cereus T spores.
Bacillus cereus T spores were prepared on fortified nutrient agar, and the spore coat and outer membrane were extracted by 0.5% sodium dodecyl sulfate-100 mM dithiothreitol in 0.1 M sodium chloride (SDS-DTT) at pH 10.5 (coat-defective spores). Coat-defective spores in L-alanine plus adenosine germinated slowly and to a lesser extent than spores not treated with SDS-DTT, as determined by decreas...
متن کاملProperties of the Bacillus subtilis spore coat.
About 70% of the protein in isolated Bacillus subtilis spore coats was solubilized by treatment with a combination of reducing and denaturing agents at alkaline pH. The residue, consisting primarily of protein, was insoluble in a variety of reagents. The soluble proteins were resolved into at least seven bands by sodium dodecyl sulfate gel electrophoresis. About one-half of the total was four p...
