Formation of Cyclobutane Pyrimidine Dimers after UVA Exposure (Dark-CPDs) Is Inhibited by an Hydrophilic Extract of Polypodium leucotomos [PDF]

Antioxidants, 2021
Exposure to sun and especially to ultraviolet radiation (UVR) exerts well known detrimental effects on skin which are implicated in malignancy. UVR induces production of cyclobutane pyrimidine dimers (CPDs), immediately during exposure and even hours ...

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

E3S 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.

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

PLoS 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 ...

2-Chloropyrimidin-4-amine

Acta Crystallographica Section E, 2012
In the title pyrimidine derivative, C4H4ClN3, the 2-chloro and 4-amino substituents almost lie in the mean plane of the pyrimidine ring, with deviations of 0.003 (1) Å for the Cl atom, and 0.020 (1) & ...

6-Chloro-N4,N4-dimethylpyrimidine-2,4-diamine

Acta Crystallographica Section E, 2012
The asymmetric unit of the title compound, C6H9ClN4, contains four independent molecules (A, B, C and D). Their main difference is the torsion angles, ranging from 1.6 (5) to 5.9 (5)°, between the methyl group and the ...

Transcription-Coupled Repair in Plants

Frontiers in Plant Science, 2012
UV-induced pyrimidine dimers block the progression of both DNA and RNA polymerases. In order to reduce the disruptive effect of these lesions on gene expression, bacteria, yeasts, and animals preferentially repair the transcribed strand of actively ...
