Intramolecular Distances and Dynamics from the Combined Photon Statistics of Single-Molecule FRET and Photoinduced Electron Transfer

Luc Reymond

Single-molecule Forster resonance energy transfer (FRET) and photoinduced electron transfer (PET) have developed into versatile and complementary methods for probing distances and dynamics in biomolecules. Here we show that the two methods can be combined ...

Selective Chemical Crosslinking Reveals a Cep57-Cep63-Cep152 Centrosomal Complex

Kai Johnsson, Pierre Gönczy, Luc Reymond, Grazvydas Lukinavicius, Keitaro Umezawa

The centrosome functions as the main microtubule-organizing center of animal cells and is crucial for several fundamental cellular processes [1]. Abnormalities in centrosome number and composition correlate with tumor progression [2, 3] and other diseases ...

Substrates for Improved Live-Cell Fluorescence Labeling of SNAP-tag

Kai Johnsson, Luc Reymond, Grazvydas Lukinavicius

The SNAP-tag labeling technology provides a simple, robust, and versatile approach to the imaging of fusion proteins for a wide range of experimental applications. Owing to the specific and covalent nature of the labeling reaction, SNAP-tag is well suited ...

A Fluorescent Sensor for GABA and Synthetic GABA(B) Receptor Ligands

Kai Johnsson, Luc Reymond, Anastasiya Masharina, Keitaro Umezawa

While gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter, suitable tools to measure its concentration in living cells with high spatiotemporal resolution are missing. Herein, we describe the first ratiometric fluorescent sensor for GABA ...

A Semisynthetic Fluorescent Sensor Protein for Glutamate

Kai Johnsson, Luc Reymond, Rudolf Griss, Matthias Albert Brun, Kui Thong Tan

We report the semisynthesis of a fluorescent glutamate sensor protein on cell surfaces. Sensor excitation at 547 nm yields a glutamate-dependent emission spectrum between 550 and 700 nm that can be exploited for ratiometric sensing. On cells, the sensor di ...

Visualizing Biochemical Activities in Living Cells through Chemistry

Kai Johnsson, Luc Reymond, Rudolf Griss, Alberto Schena, Grazvydas Lukinavicius, Karolina Bojkowska, Birgit Mollwitz, Matthias Albert Brun, Keitaro Umezawa, Anastasiya Masharina

The development of molecular probes to visualize cellular processes is an important challenge in chemical biology. One possibility to create such cellular indicators is based on the selective labeling of proteins with synthetic probes in living cells. Over ...

Chemical Biology Approaches to Membrane Homeostasis and Function

Kai Johnsson, Christian Heinis, Gerardo Turcatti, Luc Reymond, Howard Riezman, Stefan Matile

The study of membranes is at a turning point. New theories about membrane structure and function have recently been proposed, however, new technologies, combining chemical, physical, and biochemical approaches are necessary to test these hypotheses. In par ...

Semisynthesis of fluorescent metabolite sensors on cell surfaces

Horst Vogel, Kai Johnsson, Luc Reymond, Rudolf Griss, Joachim Piguet, Matthias Albert Brun, Kui Thong Tan, Ruud Peters

Progress in understanding signal transduction and metabolic pathways is hampered by a shortage of suitable sensors for tracking metabolites, second messengers, and neurotransmitters in living cells. Here we introduce a class of rationally designed semisynt ...

Conformational dynamics of bistable RNAs studied by time-resolved NMR spectroscopy

Luc Reymond, Philipp Wenter

The structural transition between two alternate conformations of bistable RNAs has been characterized by time-resolved NMR spectroscopy. The mechanism, kinetics, and thermodynamics underlying the global structural transition of bistable RNAs were delineate ...
