Reversibly Compressible Cross-Linked Polystyrene Gels, Compatible With Toluene-d and Pyridine-d, for Measurement of Residual Dipolar Couplings and Residual Chemical Shift Anisotropies.

A chemically cross-linked version of polystyrene is presented here that allows the preparation of reversibly mechanically compressible gels as NMR weakly aligning media. The gels can be successfully swollen in aromatic solvents such as toluene-d and pyridine-d, as well as in CDCl, and provided accurate measurements of D RDCs and C-RCSAs.

Carbohydrate-Binding Mechanism of the Coagulant Lectin from Seeds (cMoL) Is Related to the Dimeric Protein Structure.

This study characterized the binding mechanisms of the lectin cMoL (from Moringa oleifera seeds) to carbohydrates using spectroscopy and molecular dynamics (MD). The interaction with carbohydrates was studied by evaluating lectin fluorescence emission after titration with glucose or galactose (2.0-11 mM).
