NMR characterization and molecular modeling of fucoidan showing the importance of oligosaccharide branching in its anticomplementary activity

Fucoidan is a potent inhibitor of the human complement system whose activity is mediated through interactions with certain proteins belonging to the classical pathway, particularly the protein C4.

Flexibility observed in high resolution structures of Streptomyces aureofaciens ribonucleases determined by diffraction methods

It has been widely accepted to distinguish between static structures determined by diffraction methods and dynamic structures determined by nuclear magnetic resonance (NMR). The dynamics of NMR structures is demonstrated by an ensemble of a number of overlaid structures.

Chemical structure of β-galactofuranose-containing polysaccharide and O-linked oligosaccharides obtained from the cell wall of pathogenic dematiaceous fungus Fonsecaea pedrosoi

Fonsecaea pedrosoi is the main etiologic agent of chromoblastomycosis, usually occurring in tropical and subtropical areas. The cell wall components of pathogenic microorganisms behave as an antigen and/or ligand of the innate immune response. The cells of F. pedrosoi reacted with the ?

A 700 MHz 1H-NMR study reveals apoptosis-like behavior in human K562 erythroleukemic cells exposed to a 50 Hz sinusoidal magnetic field

Purpose: To study cell damage and possible apoptosis in K562 human erythroleukemic cells exposed for 2??h to an extremely low frequency (ELF) 50 Hz sinusoidal magnetic field with a magnetic induction of either 1 or 5 mT using high resolution proton nuclear magnetic resonance (1H-NMR) spectroscopy.

Structure and Dynamics of Cholesterol-Containing Polyunsaturated Lipid Membranes Studied by Neutron Diffraction and NMR

Scattering length distribution functions of cholesterol segments as well as of the sn-1 and sn-2 hydrocarbon chains of 18:0-22:6n3-PC were obtained by conducting experiments with specifically deuterated cholesterol and lipids.

Binding of an acceptor substrate analog enhances the enzymatic activity of human blood group B galactosyltransferase

The hydrolysis of the donor substrate uridine diphosphate galactose (UDP-Gal) by human blood group B galactosyltransferase (GTB) has been followed by nuclear magnetic resonance in the presence and in the absence of an acceptor substrate analog.

1H-NMR study on ganglioside amide protons: evidence that the deuterium exchange kinetics are affected by the preparation of samples

AbstractThe kinetics of H/2H chemical exchange of the amide proton has been suggested as one of the tools available for investigating hydrogenbond stabilizing interactions in gangliosides.

Lipid analysis of Neochloris oleoabundans by liquid state NMR

Two cultures were used in this study. One culture was "healthy" and grown in conventional media, whereas the other culture was "nitrogen-starved" and grown in media that lacked nitrate.
