HtrC is involved in proteolysis of YpeB during germination of Bacillus anthracis and Bacillus subtilis spores.
Bacterial endospores can remain dormant for decades yet can respond to nutrients, germinate, and resume growth within minutes. An essential step in the germination process is degradation of the spore cortex peptidoglycan wall, and the SleB protein in Bacillus species plays a key role in this process. Stable incorporation of SleB into the spore requires the YpeB protein, and some evidence sugges...
متن کاملEnvironmental Persistence of Bacillus anthracis and Bacillus subtilis Spores
There is a lack of data for how the viability of biological agents may degrade over time in different environments. In this study, experiments were conducted to determine the persistence of Bacillus anthracis and Bacillus subtilis spores on outdoor materials with and without exposure to simulated sunlight, using ultraviolet (UV)-A/B radiation. Spores were inoculated onto glass, wood, concrete, ...
متن کاملContributions of four cortex lytic enzymes to germination of Bacillus anthracis spores.
Bacterial spores remain dormant and highly resistant to environmental stress until they germinate. Completion of germination requires the degradation of spore cortex peptidoglycan by germination-specific lytic enzymes (GSLEs). Bacillus anthracis has four GSLEs: CwlJ1, CwlJ2, SleB, and SleL. In this study, the cooperative action of all four GSLEs in vivo was investigated by combining in-frame de...
متن کاملCortex peptidoglycan lytic activity in germinating Bacillus anthracis spores.
Bacterial endospore dormancy and resistance properties depend on the relative dehydration of the spore core, which is maintained by the spore membrane and its surrounding cortex peptidoglycan wall. During spore germination, the cortex peptidoglycan is rapidly hydrolyzed by lytic enzymes packaged into the dormant spore. The peptidoglycan structures in both dormant and germinating Bacillus anthra...
متن کاملThe mutability of Bacillus anthracis spores during germination.
The behavior of bacteria subjected to the influence of mutating agents has been studied in considerable detail, but the interpretation of the results is still largely dependent on analogy to those obtained with higher forms. The lack of clear-cut cytological evidence of a nuclear cycle has been a handicap to the bacteriologist. Studies with Tradescantia microspores by Sax (1940) showed consider...
