An objective of this research was to achieve direct, well-defined and non-rate-limiting electron transfer between respiratory enzymes and the electrode surface by means of 'Q-wires'.

The objective is to develop in vitro antigen degradation assays in order to mimic the fate of the antigen in vivo.

This research intents to redefine the limits of the electric guitar.

Examining the therapeutic potential of new semisynthetic lipopeptide antibiotics

This Thesis describes the design, synthesis and evaluation as glycoprocessing enzyme inhibitors of focused libraries of iminosugars.

Nicotinamide adenine dinucleotide (NAD+) is the substrate used for the introduction of the ubiquitous and highly dynamic PTM in which either one or multiple adenosine diphosphate ribose (ADPr) moieties are covalently attached to a nucleophilic side chain of an specific amino acid in the target protein…

Mathematical and computational analysis of the dynamics of polar transport of the plant hormone auxin.

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

The specialisation consists of 120 European Credit Transfer System (EC) points and includes courses and electives (30 - 60 EC) and and one or more research projects (60 - 90 EC).

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

Pharmacogenetics is nowadays increasingly incorporated in the clinic to better predict pharmacokinetics and optimize dosing regimens of drug treatments. While this approach has been successful and improved our prediction of drug metabolism, drug levels within patients may still commonly deviate between…

The current projects of the Molecular Physiology group focus on proteins of the endocannabinoid system, kinases and antibacterial targets. MSc- and BSc-students can contact Jessica van Krimpen-Kraaijenoord to apply for research internships.

The research described in this thesis focused on the use of bioorthogonal antigens to investigate immunological processes in antigen presenting cells. Bioorthogonal antigens are antigenic proteins produced through recombinant expression in a methionine auxotrophic E. coli strain.

Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.

Biosynthetic gene clusters (BGCs) for natural products are widespread in microbial genomes, and they are rapidly exchanged. This research assesses the factors that control the spread of BGCs and resistance genes in nature. This includes risk assessment for the spread of engineered DNA in nature.

Glycosidases are important enzymes in the turnover of polysaccharides and glycoconjugates, and are involved in a range of human pathologies including genetic disorders such as Gaucher and Pompe disease, but also in various cancers.
