Despite the enormous advances in structural studies of biological systems we are frequently left without a clear structure function correlation and cannot fully describe how different systems actually work. This introduces a major challenge for compu....

For the discovery of the physics phenomenon of nuclear magnetic resonance (NMR), Felix Bloch and Edward Purcell were awarded the Nobel Prize in Physics in 1952. NMR has then been used in a wide range of fundamental studies in physics, and in the 1960....

This lecture starts out with a very brief review of the history of protein crystallography and continue with our studies since 1970 on proteolytic enzymes and their control. Proteolytic enzymes catalyse a very simple chemical reaction, the hydrolytic....

Programmed cell death (often referred to as apoptosis) is a normal feature of animal development and tissue homeostasis. The misregulation of cell death has been implicated in a diversity of human disorders, including cancer, autoimmune diseases, he....

The acquisition of scientific knowledge largely depends on the availability of appropriate research approaches and methodologies. Novel scientific knowledge represents cultural values. On the one hand, it enriches our world-view with impacts on our....

Structural studies of the ribosome exemplify the evolution of structural studies in cell biology from the early negatively stained images of macromolecular assemblies in whole cells, to a detailed atomic understanding of the mechanism of action of a ....

The challenges associated with pursuing ribosomal crystallography can be described as a series of Everest climbing. At each step, when reaching the summit, a taller and more difficult one became exposed. Snapshots of this story will be described.__....

As a student in the early 1960s, I had the privilege to attend winter seminars organized by my mentor, W. Hoppe, and by M. Perutz, which took place in a small guesthouse in the Bavarian-Austrian Alps. The entire community of a handful of protein cry....

Cholesterol has two essential functions in our bodies: It is an important component of cell membranes and it serves as the starting material for the synthesis of bile acids, steroid hormones, and other compounds. The human body obtains necessary cho....

Supramolecular chemistry lies beyond molecular chemistry. It aims at implementing highly complex chemical systems from molecular components held together by non-covalent intermolecular forces and effecting molecular recognition, catalysis and transp....

In 1952, Felix Bloch and Edward Purcell were awarded the Nobel Prize in Physics for the description of the phenomenon of nuclear magnetic resonance (NMR). Over the years, NMR has been used in a wide range of fundamental studies in physics, and in the....
