Name  DNA photolyase, FAD-binding/Cryptochrome, C-terminal Short Name  Photolyase_FAD-bd/Cryptochr_C
Type  Domain Description  This entry represents a multi-helical domain composed of two all-alpha subdomains that is found as the C-terminal domain in cryptochrome proteins, as well as at the N-terminal of DNA photolyase where it acts as a FAD-binding domain (the N-terminal of DNA photolyase binds a light-harvesting cofactor).Photolyases and cryptochromes are related flavoproteins that bind FAD. Photolyases harness the energy of blue light to repair DNA damage by removing pyrimidine dimers. Cryptochromes (CRY1 and CRY2) are blue light photoreceptors that mediate blue light-induced gene expression [, ].DNA photolyases are DNA repair enzymes that repair mismatched pyrimidine dimers induced by exposure to ultra-violet light. They bind to UV-damaged DNA containing pyrimidine dimers and, upon absorbing a near-UV photon (300 to 500 nm), they catalyse dimer splitting, breaking the cyclobutane ring joining the two pyrimidines of the dimer so as to split them into the constituent monomers; this process is called photoreactivation. DNA photolyases require two choromophore-cofactors for their activity. All monomers contain a reduced FAD moiety, and, in addition, either a reduced pterin or 8-hydroxy-5-diazaflavin as a second chromophore. Either chromophore may act as the primary photon acceptor, peak absorptions occurring in the blue region of the spectrum and in the UV-B region, at a wavelength around 290nm [, ].
