SPIF 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 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 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 کاملSpore coat protein and enterotoxin synthesis in Clostridium perfringens.
Polyacrylamide gel profiles of Clostridium perfringens spore coat protein revealed four and occasionally five components. Pulse-chase experiments indicated that synthesis of coat protein polypeptide and enterotoxin was an early sporulation event. However, maximum synthesis occurred coincident with the onset of heat resistance.
متن کاملCharacterization of a major Bacillus anthracis spore coat protein and its role in spore inactivation.
A major Bacillus anthracis spore coat protein of 13.4 kDa, designated Cot alpha, was found only in the Bacillus cereus group. A stable ca. 30-kDa dimer of this protein was also present in spore coat extracts. Cot alpha, which is encoded by a monocistronic gene, was first detected late in sporulation, consistent with a sigma(K)-regulated gene. On the basis of immunogold labeling, the protein is ...
