The influence of G-quadruplex structure on DNA-based asymmetric catalysis using the G-quadruplex-bound cationic porphyrin TMPyP4·Cu.

Zusammenfassung

The DNA G-quadruplex-binding porphyrin TMPyP4·Cu was found to form efficient hybrid catalysts for DNA-based asymmetric catalysis when bound to DNA G-quadruplexes. Nucleobase substitution experiments using human telomere-derived G-quadruplex sequences suggest binding of the porphyrin on the 3'-face.
