J. Schraml et al., A VERSATILE NMR TECHNIQUE FOR THE IDENTIFICATION OF PHOSPHORYLATION SITES IN OLIGOSACCHARIDES, Journal of carbohydrate chemistry, 16(2), 1997, pp. 165-170
A combination of two well-established NMR methods, namely, phosphorus
decoupling and 1D-TOCSY, provides identification of phosphorylation si
tes in a simple and straightforward manner in small to medium-sized ol
igosaccharides. The method is demonstrated on Man-P-GlcMan(7)GlcNAc(2)
, a glycoprotein-derived N-linked type oligosaccharide.
