متن کاملEmerging Applications of Bacterial Spores in Nanobiotechnology
Bacterial spores are robust and dormant life forms with formidable resistance properties, in part, attributable to the multiple layers of protein that encase the spore in a protective and flexible shield. The coat has a number of features pertinent to the emerging field of nanobiotechnology including self-assembling protomers and the capacity for engineering and delivery of foreign molecules. T...
متن کاملClassic Spotlight: Bacterial Endospore Resistance, Structure, and Genetics.
Bacterial spore formation has a major impact on medicine and agriculture, and its analysis has uncovered new paradigms for understanding bacterial physiology, cell biology, and gene regulation. The existence of bacterial endospores was recognized in the 1800s by both Maximilian Perty and Louis Pasteur, and spore formation and germination in Bacillus were reported by Ferdinand Cohn and by Robert...
متن کاملSpore photoproduct lyase catalyzes specific repair of the 5R but not the 5S spore photoproduct.
Bacterial spores are remarkable in their resistance to chemical and physical stresses, including exposure to UV radiation. The unusual UV resistance of bacterial spores is a result of the unique photochemistry of spore DNA, which results in accumulation of 5-thyminyl-5,6-dihydrothymine (spore photoproduct, or SP), coupled with the efficient repair of accumulated damage by the enzyme spore photo...
