The key to the bacterium not affected by radiation

The bacterium Deinococcus radiodurans is known to withstand very well the radiation. It is capable of supporting 10,000 gray radiation (a human cell does not support more than 10 grays), making it ideal for investigating radiation protection.
Most researchers believe that, as radiation harms DNA, protection against radiation should also be the core of DNA. But U.S. researchers, led by Michael Daly, discover that the key is the proteins that form the DNA repair system. The remediation systems of the bacterium D.radiodurans appear to be more efficient than the rest of bacteria.
The key to reaching this conclusion has been manganese. And they saw that D.radiodurans has 300 times more manganese than normal. Pulling this thread they reached a chemical complex based on manganese. And they realized that this complex had the ability to neutralize free radicals created by radiation.
