Light-induced Charge Transfer in Proteins of the Cryptochrome/Photolyase Family

Long range electron transfer enables photolyases to repair radiation damaged DNA, thereby preventing mutation and cell death, and provides the basis for the signalling function of the closely related cryptochromes. In this work, multi-scale methods which combine quantum chemical and molecular mechanics approaches are used to investigate the light-induced charge transfer in proteins of the cryptochrome/photolyase family.
