Annotation:

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. The BMM approach was pioneered by Kirkwood and coworkers (Kirkwood, J.G., Macromolecules, E.P. Auer (Ed.), Gordon and Breach, New York, 1967; Kirkwood, J.G., Riseman, J., J. Chem. 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

Potassium phosphate buffer (50mM) was added such that the water:lipid molar ratio was 7.75:1. ²H-NMR measurements were made on the samples at 49°C and 65°C. The effect of all peptides was to cause an increase in lipid chain order which varied linearly with concentration. This increase was manifested by an increase in average order parameter for the entire lipid

Annotation:

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

The protein DC-SIGNR (Dendritic-cell specific ICAM3 grabbing non-integrin related) is a C-type (calcium-dependent) lectin, which binds highly-branched mannose oligosaccharides. DC-SIGNR interacts with a range of deadly diseases via surface glycans on pathogenic glycoproteins, and the ability of DC-SIGNR to increase the rate of infection of viruses including human immunodeficiency virus (HIV) and hepatitis C virus (HCV) makes the study of DC-SIGNR/oligosaccharide interactions very attractive.

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. The initial step of binding between a surface active peptide and its target membrane or membrane receptor can involve a non specific electrostatic association where positively charged amino acid residues and a negatively charged membrane surface interact. Here, the use of high resolution MAS NMR provides a highly sensitive and non perturbing way of studying the electros

A deeper insight into the structural biology of HS is key to understanding its nearuniversal functional role as a co-receptor for growth factors and morphogens. Due to the extreme difficulty in preparing homogeneous HS oligosaccharides for structural and functional studies, traditionally, oligosaccharides derived from the related molecule heparin are used as HS structural models. 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

It was found that there exist three major water environments when water is dissolved in nitrobenzene. 2H NMR has proved that these solvatomers exist irrespective of whether lithium salt is added to the system. 7Li NMR experiments suggested that the first solvatomer is majority nitrobenzene, the second a mixed solvation shell consisting of nitrobenzene and water and the third solvatomer is a large water aggregated at the glass surface. The mixed solvation state is short lived and is promoted by addition of water of by supersaturating the system upon cooling. This is a high energy state and deca
