Preparation of homogenous oligosaccharide chains from glycosphingolipids.


PMID 18415015

Abstract

After the discovery of glycosphingolipid (GSL) glycan detaching enzymes, Rhodococcal endoglycoceramidase (EGCase) and leech ceramide glycanase (CGase), the method for enzymatically releasing glycans from GSLs has become the method of choice for preparing intact ceramide-free oligosaccharide chains from GSLs. This paper describes (1) the preparation of the intact oligosaccharides from GM1 (II(3)NeuAcGgOse(4)Cer) and GbOse(4)Cer as examples to show the use of CGase to prepare intact glycan chains from GSLs, and (2) the specificity and detergent requirements of Rhodococcal EGCases for the release of glycan chains from different GSLs.
