Action mechanism of Escherichia coli DNA photolyase. II. Role of the chromophores in catalysis.


DNA photolyase repairs pyrimidine dimers in DNA in a reaction that requires visible light. Photolyase from Escherichia coli is normally isolated as a blue protein and contains 2 chromophores: a blue FAD radical plus a second chromophore that exhibits an absorption maximum at 360 nm when free in solution. Oxidation of the FAD radical is accompanied by a… (More)
