| + | Photolyases are flavoproteins, which are able to repair UV-induced DNA lesions in a light-dependant manner. According to their substrate, they can be distinguished as CPD- and (6-4) photolyases. While CPD-photolyases repair the predominantly occurring cyclobutane pyrimidine dimer lesion, (6-4) photolyases catalyse the repair of the less prominent (6-4) photoproduct. The subgroup of prokaryotic (6-4) photolyases/FeS-BCP is one of the most ancient types of flavoproteins in the ubiquitously occurring photolyase & cryptochrome superfamily (PCSf). In contrast to canonical photolyases, prokaryotic (6-4) photolyases possess a few particular characteristics, including a lumazine derivative as antenna chromophore beside the catalytically essential flavin adenine dinucleotide as well as an elongated linker region between the N-terminal alpha/beta-domain and the C-terminal all-alpha-helical domain. Furthermore, they can harbour an additional short subdomain, located at the C-terminus, with a binding site for a [4Fe-4S] cluster. So far two crystal structures of prokaryotic (6-4) photolyases have been reported. Within this study we present the high-resolution structure of the prokaryotic (6-4) photolyase from Vibrio cholerae and its spectroscopic characterization in terms of in vitro photoreduction and DNA-repair activity. | ||
