Oxidation of 2′-deoxyguanosine 5′-monophosphate photoinduced by pterin: Type I versus type II mechanism

UV-A radiation (320-400 nm) induces damage to the DNA molecule and its components through different photosensitized reactions. Among these processes, photosensitized oxidations may occur through electron transfer or hydrogen abstraction (type I) and/or the production of singlet molecular oxygen ( 1O...
