Abstract

DNA photolyases are enzymes that bind to DNA containing pyrimidine dimers: on absorption of visible light, they catalyse dimer splitting into the constituent monomers, a process called photoreactivation [PubMed6325459]. This is a DNA repair mechanism, repairing mismatched pyrimidine dimers induced by exposure to ultra-violet light [PubMed3000886]. The precise mechanisms involved in substrate binding, conversion of light energy to the mechanical energy needed to rupture the cyclobutane ring, and subsequent release of the product are uncertain [PubMed6325459]. Analysis of DNA lyases has revealed the presence of an intrinsic chromophore, all monomers containing a reduced FAD moiety, and, in addition, either a reduced pterin or 8-hydroxy-5-diazaflavin as a second chromophore [PubMed3000886, PubMed2110564]. 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 [PubMed2110564].

This domain binds a light harvesting cofactor.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 8 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Cryptochrome/photolyase, N-terminal domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 8 hidden Markov models representing the Cryptochrome/photolyase, N-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
