A new theoretical method for free energy calculations is used to compute the absolute binding constants for beta-D-glucose and methyl-beta-D-galactoside to the periplasmic glucose/galactose receptor from Salmonella typhimurium. The computer simulation results agree well with available experimental data and make

Acid hydrolysis of cell wall-rich material from young leaves of the lycophyte Selaginella apoda (L.) Spring yielded substantial amounts of 3-O-methyl-D-galactose (1) in addition to the usual major monosaccharides (glucose, galactose, arabinose, xylose and galacturonic acid). The yield of 1

A protocol based on saturation transfer difference (STD) NMR spectra was developed to characterize the binding interactions at an atom level, termed group epitope mapping (GEM). As an example we chose the well-studied system of galactose binding to the 120-kDa

Mistletoe lectin is a potent biohazard. Lectin activity in the toxic dimer primarily originates from the 2gamma-subdomain (Tyr-site) of the B-subunit. Crystallographic information on lectin-sugar complexes is available only at acidic pH, where lectin activity is low. Thus, we mapped

Journal of the American Chemical Society, 127(20), 7379-7386 (2005-05-19)
The existence of stabilizing carbohydrate-aromatic interactions is demonstrated from both the theoretical and experimental viewpoints. The geometry of experimentally based galactose-lectin complexes has been properly accounted for by using a MP2/6-31G(d,p) level of theory and by considering a counterpoise correction
