hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-(2->8)- glycosidic linkages of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates
active site, Arg498, Glu258, Tyr317, and Tyr262 are catalytic residues, with the aromatic ring of the latter being important for function
hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-(2->8)- glycosidic linkages of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates
trans-sialidase preferring the transfer of sialic acids from sialoglycoconjugates to beta-galactosyl acceptor molecules, ping-pong, double diplacement catalytic mechanism, Tyr342 is important, Asp59 is the acid/base residue, enzyme-substrate complex structure, covalent sialyl-enzyme intermediate
-
hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-(2->8)- glycosidic linkages of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates
catalytic chemistry involves the formation of a covalent intermediate with an active site tyrosine nucleophile
