The challenge of establishing a sustainable and circular economy for materials in medicine and technology necessitates bioinspired design. Nature's intricate machinery, forged through evolution, relies on a finite set of biomolecular building blocks with through-bond and through-space interactions. Repurposing these molecular building blocks requires a seamless integration of computational modeling, design, and experimental validation. The tools and concepts developed in this thesis pioneer new directions in peptide-materials design, grounded in fundamental principles of physical chemistry. We present a synergistic approach that integrates experimental designs and computational methods, specifically molecular dynamics simulations, to gain in-depth molecular insights crucial for advancing the …

The bacterial tyrosine kinases (BY-kinase) represent a class of membrane-bound enzymes that utilize a cycle of auto-phosphorylation and de-phosphorylation to drive the synthesis and export of exopolysaccharides in both Gram-positive and Gram-negative bacteria. The catalytic domain of BY-kinases utilizes a P-loop nucleoside triphosphatase (NTPase) fold that is commonly used by NTPases and small molecule kinases, being the only protein kinase to do so. In the work presented in this thesis, we aimed to obtain an understanding of the mechanisms of the BY-kinases’ unconventional deployment of P-loop scaffold to phosphorylate on tyrosine. We used the BY-kinase of Escherichia coli (K12) as …

Molecular recognition is the basis of biological mechanisms and is a key element to consider while formulating effective and safe drugs. Pharmaceutical drugs are designed so as to bind a target protein even at very low concentrations to alter the diseased conditions without interfering with normal biological processes. In a rational drug design process, this is achieved by acquiring information about the chemical structure and the physical and chemical properties of the target protein receptor to gain insights on how changing the chemical composition of the substrate drug could affect the protein-drug interaction and binding affinities. Computational models are used …
