In this study, the cloning, purification and initial characterization of carbonic anhydrase (DrCA) enzyme which we consider to be important in resistance physiology from extremely radioresistant bacteria Deinococcus radiodurans is performed. addition, effect increased gamma irradiation doses on pH-related DrCA activity was determined. after radiation treatment showed that continuously by 6 fold...
BACKGROUND Globally, about 20% of cultivated land is now affected by salinity. Salt tolerance is a trait of importance to all crops in saline soils. Previous efforts to improve salt tolerance in crop plants have met with only limited success. Bacteria of the genus Deinococcus are known for their ability to survive highly stressful conditions, and therefore possess a unique pool of genes conferr...
With the aid of an efficient, precise, and almost error-free DNA repair system, Deinococcus radiodurans can survive hundreds of double-strand breaks inflicted by high doses of irradiation or desiccation. RecA of D. radiodurans (DrRecA) plays a central role both in the early phase of repair by an extended synthesis-dependent strand annealing process and in the later more general homologous recom...
Deinococcus radiodurans has an efficient DNA double strand break (DSB) repair mechanism, which helps it to mend hundreds of DSBs produced after exposure to the exceptionally high doses of ionizing radiation and shows no measurable loss of cell viability. This tolerance is well above the DSB tolerance by any other organism. The better catalytic efficiency of different proteins associated with DS...
