Short Note on Glycosyltransferases andSialytransferases

Abstract

Glycosyltransferases catalyze glycosidic bond arrangement utilizing the sugar donors containing a nucleoside phosphate or lipid phosphate leaving group. these are two auxiliary folds, GT-A and GT-B, have been recognized for the nucleotide sugar-dependent proteins, but other folds are presently showing up for the soluble spaces of lipid phosphosugar-dependent glycosyl transferases. Sialic acids are imperative recognition sites in protein- and lipidlinked glycans of higher living beings and selected microscopic organisms and protozoa. They are also conspicuous in human milk oligosaccharides.
