Journal ArticleDOI
Intramolecular Charge Transfer as Probing Reaction: Fluorescence Monitoring of Protein-Surfactant Interaction
TL;DR: In this article, the ICT emission from EDAC increases with surfactant concentration and reaches a maximum at the critical micelle concentration of SDS, which can be employed as a simple technique for following micellization.
Journal ArticleDOI
Fluorescent Amino Acid Undergoing Excited State Intramolecular Proton Transfer for Site-Specific Probing and Imaging of Peptide Interactions
Marianna Sholokh,Marianna Sholokh,Oleksandr M. Zamotaiev,Ranjan Das,Viktoriia Y. Postupalenko,Ludovic Richert,Denis Dujardin,Olga A. Zaporozhets,Vasyl G. Pivovarenko,Andrey S. Klymchenko,Yves Mély +10 more
TL;DR: A fluorescent l-amino acid bearing the 4'-methoxy-3-hydroxyflavone fluorophore (M3HFaa) that shows dual emission, as a result of an excited state intramolecular proton transfer (ESIPT), which was found to be substantially more sensitive to hydration as compared to previous analogues.
Journal ArticleDOI
Conquering 2-Aminopurine’s Deficiencies: Highly Emissive Isomorphic Guanosine Surrogate Faithfully Monitors Guanosine Conformation and Dynamics in DNA
Marianna Sholokh,Rajhans Sharma,Dongwon Shin,Ranjan Das,Olga A. Zaporozhets,Yitzhak Tor,Yves Mély +6 more
TL;DR: Being able to perfectly substitute G residues, d(th)G will transform nucleic acid biophysics by allowing, for the first time, to selectively and faithfully monitor the conformations and dynamics of a given G residue in a DNA sequence.
Journal ArticleDOI
Energetic and Dynamic Aspects of Intramolecular Proton Transfer in 4-Methyl-2,6-diformylphenol: A Detailed Analysis with AM1 Potential Energy Surfaces
TL;DR: In this article, an analysis of the under-barrier vibrational levels supported by the asymmetric double-well potential characterizing two forms, it appears that proton transfer may occur by a vibrationally assisted overbarrier process as well as by a tunneling mechanism following the S0 → S1 excitation.
Journal ArticleDOI
Translational diffusion of fluorescent probes on a sphere: Monte Carlo simulations, theory, and fluorescence anisotropy experiment
TL;DR: A Monte Carlo simulation method was developed to obtain the fluorescence anisotropy decays for the general case of molecular dipoles tilted at an angle α to the surface normal as discussed by the authors.
