Genetically encoded betaxanthin-based small-molecular fluorescent reporter for mammalian cells

Karl Gademann, Leo Scheller

We designed and engineered a dye production cassette encoding a heterologous pathway, including human tyrosine hydroxylase and Amanita muscaria 4,5-DOPA dioxygenase, for the biosynthesis of the betaxanthin family of plant and fungal pigments in mammalian c ...

A multi-scale time-resolved study of photoactivated dynamics in 5-benzyl uracil, a model for DNA/protein interactions

Majed Chergui, Enrico Pomarico

We combine fluorescence up-conversion and time correlated single photon counting experiments to investigate the 5-benzyl uracil excited state dynamics in methanol from 100 fs up to several ns. This molecule has been proposed as a model for DNA/protein inte ...

Semisynthetic sensor proteins enable metabolic assays at the point of care

Kai Johnsson, Rudolf Griss, Qiuliyang Yu, Lin Xue, Julien Hiblot

Monitoring metabolites at the point of care could improve the diagnosis and management of numerous diseases. Yet for most metabolites, such assays are not available. We introduce semisynthetic, light-emitting sensor proteins for use in paper-based metaboli ...

Reinforcement Learning Using a Continuous Time Actor-Critic Framework with Spiking Neurons

Wulfram Gerstner, Nicolas Frémaux

Animals repeat rewarded behaviors, but the physiological basis of reward-based learning has only been partially elucidated. On one hand, experimental evidence shows that the neuromodulator dopamine carries information about rewards and affects synaptic pla ...

The Mouse Eugenol Odorant Receptor: Structural and Functional Plasticity of a Broadly Tuned Odorant Binding Pocket

Horst Arthur Vogel, Horst Pick, Olivia Baud, Sylvain Etter

Molecular interactions of odorants with their olfactory receptors (ORs) are of central importance for the ability of the mammalian olfactory system to detect and discriminate a vast variety of odors with a limited set of receptors. How a particular OR bind ...

Experimentally Facile Controlled Polymerization of N-Carboxyan hydrides (NCAs), Including O-Benzyl-L-threonine NCA

It is demonstrated here that three different alpha-amino N-carboxyanhydrides (NCAs), including for the first time O-benzyl-L-threonine NCA, can be polymerized in a controlled/"living" fashion without the need for transition metal catalysts or complex custo ...

Chiral recognition and supramolecular self-assembly of adsorbed amino acids and dipeptides at the submolecular level

Magalí Alejandra Lingenfelder

This thesis deals with the supramolecular organization of chiral aminoacids and dipeptides on metal surfaces. The emergence of homochirality in biomolecular systems is one of the most intriguing open questions of Nature. The self-assembly and amplification ...
