Photoadduct
Webthymine-adenine photoadduct has been detected in UV-irradiated DNA as well as in oligo- and poly(dA-dT). The quantum yield for its formation ranges from about 7xlO~4 mole/E in the deoxydinucleoside monophosphate to 1 x 10~5 mole/E in native calf thymus DNA (75); the photoreaction is strongly quenched by base pairing. WebAbstract. The photochemistry of 4'-aminomethyl-4,5',8-trimethylpsoralen (AMT) with poly(dA-dT) and calf thymus DNA was studied. The extent of photoadduct formation and the …
