WebMay 23, 2011 · It is widely accepted (1, 2) that CPD repair by photolyase proceeds by the following steps (see Fig. 1).A CPD recognized by the enzyme is flipped out of the double helix in order to enter the substrate binding pocket and to closely approach the FAD cofactor (see structure in Fig. 1).Once the substrate is bound, light is required to excite FADH-, …
Photolyases bind complementary DNA strands and break certain types of pyrimidine dimers that arise when a pair of thymine or cytosine bases on the same strand of DNA become covalently linked. The bond length of this dimerization is shorter than the bond length of normal B-DNA structure which produces an incorrect template for replication and transcription. The more common covalent linkage involves the formation of a cyclobutane bridge.
