Engineered Phenylalanine Ammonia-Lyases for the Enantioselective Synthesis of Aspartic Acid Derivatives

Biocatalytic hydroamination of alkenes is an efficient and selective method to synthesize natural and unnatural amino acids. Phenylalanine ammonia-lyases (PALs) have been previously engineered to access a range of substituted phenylalanines and heteroaryla ...

Gallocin A, an Atypical Two-Peptide Bacteriocin with Intramolecular Disulfide Bonds Required for Activity

Alexis Joseph Proutière

Streptococcus gallolyticus subsp. gallolyticus (SGG) is an opportunistic gut pathogen associated with colorectal cancer. We previously showed that colonization of the murine colon by SGG in tumoral conditions was strongly enhanced by the production of gall ...

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

Leo Scheller, Karl Gademann, Simon Sieber

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, Mohammadhassan Valadan

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 ...

C-Terminal Bioconjugation of Peptides through Photoredox Catalyzed Decarboxylative Alkynylation

Jérôme Waser, Franck Le Vaillant, Marion Marie-Agnès Garreau

We report the first decarboxylative alkynylation of the C-terminus of peptides starting from free carboxylic acids. The reaction is fast, metal-free, and proceeds cleanly to afford alkynylated peptides with a broad tolerance for the C-terminal amino acid. ...

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 ...

Novel inhibitors of the enzyme activated factor xii (fxiia)

Christian Heinis, Jonas Alfred Karl Wilbs, Vanessa Baeriswyl, Simon Jan Middendorp

The present invention relates to a bicyclic inhibitor of the coagulation enzyme activated factor XII (FXIIa) comprising or consisting of the peptide (X1)(X2)(X3)n(X4)(X5)(X6)m(X7)(X9)l(X10)(X11)(X12)(X13)(X14)k(X15)(X16), wherein (X1) is present or absent ...

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 ...
