Perspectives on Cyclobutane Pyrimidine Dimers—Rise of the Dark Dimers [PDF]

open access: bronzePhotochemistry and Photobiology, 2021
ABSTRACTSome early reports demonstrate that levels of cyclobutane pyrimidine dimers (CPD) may increase after UVR exposure had ended, although these observations were treated as artifacts. More recently, it has been shown unequivocally that CPD formation does occur post‐irradiation, with maximal levels occurring after about 2–3 h.

The compost metagenome as a source of T4 bacteriophage pyrimidine dimer glycosylase homologues [PDF]

open access: yesE3S Web of Conferences, 2021
Compost is a promising source of thermotolerant enzymes for their application in biotechnology. Homologues of bacteriophage T4 DNA glycosylase can find their application in pharmaceuticals and perfumery.

Photolyase Production and Current Applications: A Review

open access: yesMolecules, 2022
The photolyase family consists of flavoproteins with enzyme activity able to repair ultraviolet light radiation damage by photoreactivation. DNA damage by the formation of a cyclobutane pyrimidine dimer (CPD) and a pyrimidine-pyrimidone (6-4 ...

Recombination between homologous chromosomes induced by unrepaired UV-generated DNA damage requires Mus81p and is suppressed by Mms2p. [PDF]

open access: yesPLoS Genetics, 2015
DNA lesions caused by UV radiation are highly recombinogenic. In wild-type cells, the recombinogenic effect of UV partially reflects the processing of UV-induced pyrimidine dimers into DNA gaps or breaks by the enzymes of the nucleotide excision repair ...

DNA backbone conformation in cis–syn pyrimidine[]pyrimidine cyclobutane dimers [PDF]

open access: bronzeBiopolymers, 1980
A theoretical calculation involving minimization of energy functions was made to determine the conformation of a deoxydinucleoside monophosphate pyrimidine[ ]pyrimidine cis-syn cyclobutane dimer. Such single-stranded moieties are useful models for the in uiuo situation because single strands are more easily damaged, and the damage inhibits the normal ...

Guanine Deaminase Stimulates Ultraviolet-induced Keratinocyte Senescence in Seborrhoeic Keratosis via Guanine Metabolites

open access: yesActa Dermato-Venereologica, 2020
DNA damage and oxidative stress play a critical role in photoageing. Seborrhoeic keratosis (SK) affects sunlight-exposed sites in aged individuals. This study examined the mechanism of photoageing in SK.

Methyl 2-[2-(benzyloxycarbonylamino)propan-2-yl]-5-hydroxy-6-methoxypyrimidine-4-carboxylate

open access: yesActa Crystallographica Section E, 2011
In the title compound, C18H21N3O6, a pyrimidine derivative, the dihedral angle between the benzene and pyrimidine rings is 52.26 (12)°.

Twist and turn: a revised structural view on the unpaired bubble of class II CPD photolyase in complex with damaged DNA

open access: yesIUCrJ, 2018
Cyclobutane pyrimidine dimer (CPD) photolyases harness the energy of blue light to repair UV-induced DNA CPDs. Upon binding, CPD photolyases cause the photodamage to flip out of the duplex DNA and into the catalytic site of the enzyme.
