Abstract:
Sinefungin is an antibiotic and a close structural analog of S-adenosylmethionine, a co-factor for a vast number of enzymes. Sinefungin is one of a class of natural products containing both nucleoside and amino acid moieties. Sinefungin is a conformationally complex molecule. Because the sinefungin molecule consists of a planar adenine ring capable of both syn and anti orientation with respect to a conformationally mobile ribose ring and a flexible amino acid side chain, it has a wide range of conformational features that may be related to its bioactivity. Both lD and 2D F1NMR methods were use

On the bead modeling methodology, or BMM, a macromolecule is modeled as a rigid, non-overlapping bead array with arbitrary radii.

Phys., 1948, 16, 565) and applied to such transport properties as diffusion, sedimentation, and viscosity. With the availability of computers, a number of investigators extended the work to account for the detailed shape of biomolecules in the 1970s. A principle objective of my research

Abstract:
Structure determination of membrane proteins by solution nuclear magnetic resonance spectroscopy requires that they can be incorporated into detergent micelles in order to ensure that they are maintained in a folded, water-soluble state. However, some detergents appear to disrupt structurally important interactions between transmembrane (TM) helices, while others produce micelle-protein complexes that may be too large for solution NMR. As a result there are a limited number of detergents suitable for solution NMR studies, making the search for better solution conditions one of the remaining ch

Interactions between peptides and biological lipid membranes play a crucial role in many cellular processes such as in the mechanism behind Alzheimer’s disease where amyloid-beta peptide (Abeta)is thought to be a key component.

In this study a number of authentic HS derived hexasaccharides, in addition to heparin derived hexasaccharides, have been purified in sufficient quantity to permit a detailed NMR and molecular modelling based analysis
