Photocontrolled Binding and Binding-Controlled Photochromism within Anthracene-Modified DNA
نویسندگان
چکیده
Modified DNA strands undergo a reversible light-induced reaction involving the intramolecular photodimerization of two appended anthracene tags. The photodimers exhibit markedly different binding behavior toward a complementary strand that depends on the number of bases between the modified positions. By preforming the duplex, photochromism can be suppressed, illustrating dual-mode gated behavior.

DNA gated photochromism and fluorescent switch in a thiazole orange modified diarylethene.
Thiazole orange-modified diarylethene (1) shows weak fluorescence but no photochromism in aqueous solution. When binding with DNA, the fluorescence of 1 is enhanced drastically and the photochromic reactivity is unlocked. This kind of DNA-responsive photoswitchable system can be used for imaging nucleic acids within cells.
متن کاملExploiting anthracene photodimerization within peptides: light induced sequence-selective DNA binding.
The unprecedented use of anthracene photodimerization within a protein or peptide system is explored through its incorporation into a DNA-binding peptide, derived from the GCN4 transcription factor. This study demonstrates an effective and dynamic interplay between a photoreaction and a peptide-DNA assembly, with each process able to exert control over the other.
متن کاملReversible photocontrol of DNA binding by a designed GCN4-bZIP protein.
Synthetic photocontrolled proteins could be powerful tools for probing cellular chemistry. Several previous attempts to produce such systems by incorporating photoisomerizable chromophores into biomolecules have led to photocontrol but with incomplete reversibility, where the chromophore becomes trapped in one photoisomeric state. We report here the design of a modified GCN4-bZIP DNA-binding pr...

In this study at first , an azo dye, 2,7- naphthalenediol, 2-[(4-Bromophenyl)azo (BPAND) as a ligand has been synthesized by addition of p-Bromoaniline to the modified montomorillonite K10 clay. This ligand was characterized using 1H-NMR, UV-Vis and IR spectroscopies. Subsequently, its interaction with calf thymus deoxyribonucleicacid ,ct-DNA was investigated in 5 mM phosphate buffer solution, ...
