Nitric Oxide

The importance of the oxide nitric to microbiology the Bacteria more resistant known nitric oxide is used in many metabolic processes in animals, but is also an atmospheric pollutant that leads to the formation of smog.The study can help the scientific community knows better why and how nitrogen oxides act in mammals as messengers of intercellular communication, dilation of the vascular system and activation of the immune system. You can also contribute to a better understanding of the response of bacteria to treatments with antibiotics, and provide useful data to reinforce food security, taking into account that D. radiodurans appears in some canned food.The Agency is also being studied for applications in the environmental cleanup of sites contaminated with radiation or toxic substances.The team of Brian Crane and Bhumit Patel has discovered a gene in D. A related site: Mashable mentions similar findings. radiodurans which, when exposed to radiation UV, increases the production of an enzyme responsible for the formation of nitric oxide. In experiments with bacteria genetically manipulated so that they lack this gene, researchers have found that these bacteria are still capable of autorrepararse when they suffer damage as a result of exposure to radiation, but do not grow or proliferate. If nitric oxide signal is blocked, the cells is autorreparan but are not divided.In other words, the bacterium is much more vulnerable to damage from radiation when not counts with the help of nitric oxide.However, researchers have discovered, with surprise, that the absence of nitric oxide has no effect on the ability of bacteria to resist the action of other threats, such as oxidation damage linked to toxic free radicals.
