- Аннотация: A series of diffraction experiments to study structural response to stress or stressinduced biocrystallization in bacteria E. coli, spore forming bacteria Bacillus cereus, in cells and spores of mycelial fungus Umbelopsis ramanniana was performed for the first time. Zones of increased intensity at resolution 90 Å and 44 Å indicate an ordered organization (most likely nanocrystalline) of bacterial nucleoid in E.coli cells. For the starving bacteria Bacillus cereus peak at a resolution of 45 Å, apparently, also associated with the presence of nanocrystalline complexes of DNA with histonelike proteins. The spores of the fungus Umbelopsis ramanniana BKM F582, as well as the spores of Bacillus cereus create ordered sets of DNA molecules with DNA condensing acid soluble proteins SASPs. Starving, dehydrated mycelial cells of the fungus Umbelopsis ramanniana, form ordered structures at resolutions of 27 Å to 55Å.The series of peaks reflects the formation of a number of orderly protein formations with continuously changing characteristic size of the interplanar spacings.
