In classical models of radiation toxicity, DNA is the molecule that is most affected by ionizing radiation (IR). However, recent data show that the amount of protein damage caused during irradiation of bacteria is better related to survival than to DNA damage. In this Opinion article, a new model is presented in which proteins are the most important target in the hierarchy of macromolecules affected by IR. A first line of defence against IR in extremely radiation-resistant bacteria might be the… 
Ionizing Radiation Resistance in Deinococcus Radiodurans
TLDR
The general characteristics and ionizing radiation resistance mechanisms of D. radiodurans are reviewed and discussed in this paper.
Biology of extreme radiation resistance: the way of Deinococcus radiodurans.
TLDR
The reviewed biology of resistance to radiation and other sources of oxidative damage concludes that the impact of protein damage on the maintenance of life has been largely underestimated in biology and medicine.
10.1 Deinococcus radiodurans: Revising the Molecular Basis for Radiation Effects on Cells
TLDR
A growing body of experimental evidence now supports that naturally sensitive bacteria are killed by radiation mainly owing to protein oxidation, whereas extreme resistance in bacteria is achieved by protecting enzymes and the repair functions they catalyze.
Experimental evolution of extremophile resistance to ionizing radiation.
Recent progress in understanding the molecular mechanisms of radioresistance in Deinococcus bacteria
TLDR
This paper is focused on the most recent findings regarding the molecular background of radioresistance and on Deinococcus bacteria response to oxidative stress, and novel proteins and genes involved in the highly regulated DNA repair processes, and enzymatic and non-enzymatic antioxidant systems are presented.
eath by protein damage in irradiated cells
TLDR
These findings offer fresh insight into the molecular mechanisms of radiation resistance and present themselves as new opportunities to study and control oxidative stress anganese (II) antioxidant complexes eactive oxygen species (ROS) etabolite accumulation.
Oxidative Stress Resistance in Deinococcus radiodurans
TLDR
These findings challenge the concept of DNA as the primary target of radiation toxicity while advancing protein damage, and the protection of proteins against oxidative damage, as a new paradigm of radiationoxicity and survival.
Death by protein damage in irradiated cells.
The diversity and commonalities of the radiation-resistance mechanisms of Deinococcus and its up-to-date applications
TLDR
This article summarizes the latest research on the radiation-resistance mechanisms of Deinococcus and prospects its biotechnological application potentials.
Modulating Radiation Resistance: Novel Protection Paradigms Based on Defenses against Ionizing Radiation in the Extremophile Deinococcus radiodurans
TLDR
It is demonstrated that ultrafiltered, protein-free preparations of D. radiodurans cell extracts prevent protein oxidation at massive doses of IR, providing the basis for a new approach to radioprotection.

Radiation Resistance among Bacteria
TLDR
It is stressed that the initial physical and chemical changes induced by radintion are extremely rapid, whereas subsequent mutations and death require processes of cell metabolism that take a comparatively long time before they become manifest.
Deinococcus radiodurans: what belongs to the survival kit?
TLDR
This work discusses different hypotheses and possibilities that have been suggested to contribute to radioresistance and proposes that D. radiodurans combines a variety of physiological tools that are tightly coordinated.
Deinococcus radiodurans — the consummate survivor
TLDR
It seems that D. radiodurans uses mechanisms that limit DNA degradation and that restrict the diffusion of DNA fragments that are produced following irradiation, to preserve genetic integrity.
Accumulation of Mn(II) in Deinococcus radiodurans Facilitates Gamma-Radiation Resistance
TLDR
It is proposed that Mn(II) accumulation facilitates recovery from radiation injury and exhibits a concentration-dependent response to manganous chloride [Mn(II).
Protein Oxidation Implicated as the Primary Determinant of Bacterial Radioresistance
TLDR
It is presented the case that protein, rather than DNA, is the principal target of the biological action of IR in sensitive bacteria, and extreme resistance in Mn-accumulating bacteria is based on protein protection.
Genome of the Extremely Radiation-Resistant Bacterium Deinococcus radiodurans Viewed from the Perspective of Comparative Genomics
TLDR
An extensive comparative sequence analysis of the Deinococcus genome suggests that several different biological mechanisms contribute to the multiple DNA repair-dependent phenotypes of this organism.
DNA repair in the extremely radioresistant bacterium Deinococcus radiodurans
TLDR
Deinococcus radiodurans may serve as an easily accessible model system for the double‐strand‐break‐initiated interchromosomal recombination that occurs in eukaryotic cells during mitosis and meiosis.
