Cyclobutane-type pyrimidine dimers in polynucleotides.

Science (New York, N.Y.), 1966
The formation of cyclobutane-type dimers between adjacent pyrimidine residues in model polynucleotides or DNA may be represented by the general scheme See pdf 379.pdf Whereas the formation of all other known photoproducts follows the irreversible path See pdf 379.pdf Thus dimers are distinguished from other photoproducts by the fact that they can be ...

Mass spectra of some dimeric photoproducts of pyrimidines

Tetrahedron, 1969
Abstract The mass spectra of photo-cycloaddition products of thymines and uracils and a photocoupled product of 5-bromouracil have been measured. Characteristic fragmentation has been documented for dimers joined through a cyclobutane ring, adducts derived from oxetane and azetidine linkages and a coupled product linked through a 5,5′-bond.

Photomonomerization of pyrimidine dimers by indoles and proteins

Journal of Theoretical Biology, 1976
Abstract Model systems for the study of photoreactivation have been developed that utilize a variety of indole derivatives. These systems can split uracil cis-syn cyclobutadipyrimidine, either free or in RNA, when irradiated at wave-lengths absorbed only by the indole moiety. The ability of indole compounds to split dimers is closely related to their

PHOTOREPAIR OF NONADJACENT PYRIMIDINE DIMERS BY DNA PHOTOLYASE

Photochemistry and Photobiology, 1995
Abstract— Photolyases reverse the harmful effects of UV light on cells by converting pyrimidine dimers (Pyr[]Pyr) into two pyrimidine monomers by utilizing near‐UV and visible light. Previous work has shown that photolyase repairs T[c,s]T and T[t,s]T in DNA as well as U[]U in RNA, all of which are formed by joining the two adjacent pyrimidines in a ...

INCANDESCENT LAMPS CAN PRODUCE PYRIMIDINE DIMERS IN DNA

Photochemistry and Photobiology, 1985
Abstract—DNA molecules that have been exposed to light from a 150 W incandescent spot lamp are nicked by the Micrococcus luteus endonuclease specific for cyclobutyl‐type pyrimidine dimers. The production of these enzyme‐sensitive sites increases with increasing spot lamp exposure.

An Enzymatic Assay for Pyrimidine Dimers in DNA

1975
An assay for pyrimidine dimers in DNA employing the T4 endonuclease V is described. The assay can detect approximately 50 dimers per Escherichia coli genome, or the effect of 10 ergs/mm2 ultraviolet irradiation.
