Abstract

Escherichia coli DNA photolyase (photoreactivating enzyme) was purified to homogeneity from a strain that greatly overproduces the protein. The purified enzyme has absorption peaks at 280 and 380 nm, a fluorescence emission peak at 480 nm and, upon denaturation, releases a chromophore that has the spectroscopic properties of flavin adenine dinucleotide (FAD), indicating that FAD is an intrinsic chromophore of the enzyme.
