A look back at the early literature on reactive oxygen species (ROS) gives the impression that these small inorganic molecules had a singular defined role, that of host defence in mammalian systems. However, it is now known that their roles also incl... Read More about Doing the unexpected: Proteins involved in hydrogen peroxide perception.
