Analysis of glycosphingolipids: recombinant endoglycoceramidase II (rEGCase II)

Recombinant endoglycoceramidase II (rEGCase II) is an endo-type enzyme that cleaves the linkages between oligosaccharides and ceramides of acidic and neutral glycosphingolipids, producing intact oligosaccharide and ceramide byproducts. This enzyme does not act on galactosyl- or glucosylceramides. It also does not hydrolyze cerebrosides, sulfatides, sphingomyelin, glycoglycerolipids, or glycoproteins. Globo-type glycosphingolipids are highly resistant to rEGCase II hydrolysis. rEGCase II is most suited to the structural analysis of glycosphingolipids.

Purity

rEGCase is free from the following exoglycosidase activities: alpha-galactosidase, beta-galactosidase, alpha-N-acetylgalactosaminidase, beta-N-acetylgalactosaminidase, beta-N-acetyl-glucosaminidase, alpha-mannosidase, alpha-fucosidase, and sialidase. This enzyme is also free from glycopeptidase, endo-beta-N-acetyglucosaminidase, proteinase, and sphingomyelinase activities.
