The extraordinary resistance to UV radiations of a manganese superoxide dismutase of Deinococcus radiodurans offers promising potentialities in skin care applications.

In the present study we investigated on a Mn-SOD deriving from the extremophilic bacterium Deinococcus radiodurans and, after its expression in E.coli, the Mn-SOD was characterized in terms of chemical and physical properties. Its extraordinary features in terms of UV resistance prompted us to investigate further about its potential applications in the dermo-cosmetic sector. It was expressed in Solanum lycopersicum (tomato) cell cultures with the main goal of developing a new ingredient, capable of keeping its ROS neutralizing activity once exposed to UV radiations and even when added to skin care formulas.
