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 ...

Semisynthetic Fluorescent Sensor Proteins Based on Self-Labeling Protein Tags

Matthias Albert Brun

Genetically encoded fluorescent sensor proteins offer the possibility to probe the concentration of key metabolites in living cells. The approaches currently used to generate such fluorescent sensor proteins lack generality, as they require a protein that ...

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 ...
