Researchers Uncover Protection Mechanism Of Radiation-resistant Bacterium
Science Daily — Results of a recent study titled “Protein Oxidation
Implicated as the Primary Determinant of Bacterial Radioresistance,”
will be published in the March 20 edition of PLoS Biology. The study,
headed by Michael J. Daly, Ph.D., associate professor at the Uniformed
Services University of the Health Sciences (USU), Department of
Pathology, shows that the ability of the bacterium Deinococcus
radiodurans to endure and survive enormous levels of ionizing radiation
(X-rays and gamma-rays) relies on a powerful mechanism that protects
proteins from oxidative damage during irradiation.
