In the first chapter of this thesis, the development of two new reactions for the synthesis of vinyl ketenimines and alpha-oxo-ketenimines from isocyanides is presented. These palladium-catalyzed transformations both feature an isocyanide insertion / beta- ...
In nature, individual histones in the same nucleosome can carry identical (symmetric) or different (asymmetric) post-translational modification (PTM) patterns, increasing the combinatorial complexity. Embryonic stem cells exhibit bivalent nucleosomes, some ...
Synthetic protein switches are proteins that can be controlled by an external input, and are useful tools to probe protein function. Antibody fragments and antibody mimetics can be selected to bind, activate, or inhibit several diverse protein targets. Nev ...
Bioreporters are living cells that generate an easily measurable signal in the presence of a chemical compound. They acquire their functionality from synthetic gene circuits, the configuration of which defines the response signal and signal-to-noise ratio. ...
Recent progress in protein engineering, empowered by the rapidly evolving fields of synthetic biology and DNA synthesis, has enabled the generation of various custom-designed proteins. Their thorough analysis has led to applications in areas including medi ...
The availability of different levels of omics data helps us to observe cells with higher resolution and from different perspectives. However, complete understanding of metabolism lags behind in explaining the chemodiversity observed in living organisms – t ...
Beta-glucosidase (BGL) is a rate-limiting enzyme for cellulose hydrolysis as it acts in the final step of lignocellulosic biomass conversion to convert cellobiose into glucose, the final end product. Most of the fungal strains used for cellulase production ...
Photorelease of caged compounds is among the most powerful experimental approaches for studying cellular functions on fast timescales. However, its full potential has yet to be exploited, as the number of caged small molecules available for cell biological ...
Since the origins of DNA-based life, the enzyme ribonucleotide reductase (RNR) has spurred proliferation because of its rate-limiting role in de novo deoxynucleoside-triphosphate (dNTP) biosynthesis. Paradoxically, the large subunit, RNR-alpha, of this obl ...
Here we discuss, how by applying chemical concepts to biological problems, methods have been developed to map spatiotemporal regulation of proteins and small-molecule modulation of proteome signaling responses. We outline why chemical-biology platforms are ...
