Ancient Protein-making Enzyme Protects DNA

An enzyme best known for its fundamental role in building proteins also works as protector of DNA during times of cellular stress, find scientists at The Scripps Research Institute (TSRI). The finding is remarkable on a basic science level but also points the way to possible therapeutic applications. Strategies that enhance the DNA-protection function of the enzyme, TyrRS, could help protect people from radiation injuries as well as from hereditary defects in DNA ...
