Synthetic biology and systems chemistry demonstrate a growing interest in modified nucleotides to achieve an enzymatically stable artificial nucleic acid. A potential candidate system is xylose-DNA, in which the 2'-deoxy-beta-D-ribo-furanose is subst

A tripyrrole peptide-Hoechst conjugate (FPH-1) has been designed which recognizes nine dA/dT base pair A/T rich dsDNA sequences at subnanomolar concentrations and complexes its targets at near diffusion controlled rates to form a fluorescent product.

The energetic provisions for Lowdin's DNA mutational mechanism (Lowdin, P. O. Rev. Mod. Phys. 1963, 35, 724) of the formation of substitution DNA mutations were investigated for the guanine·cytosine Watson−Crick base pair. The structures studied i

A solution state NMR study has shown that d(G4T3G4) in the presence of (15)NH4(+) ions folds into a single bimolecular G-quadruplex structure in which its G-tracts are antiparallel and the two T3 loops span along the edges of the outer G-quartets on

Variations in the hydrogen bond network of the Oxy-1.5 DNA guanine quadruplex have been monitored by trans-H-bond scalar couplings, (h2)J(N2N7), for Na(+)-, K(+)-, and NH(4)(+)-bound forms over a temperature range from 5 to 55 degrees C. The variatio

EDTA-derivatized deoxythymidine (dT-EDTA), incorporated into DNA and complexed to Fe2+ in the presence of dithiothreitol, is a widely used reagent for sequence-specific cleavage of duplex DNA. Using HPLC/electrospray mass spectrometry, we show that c
