Description générale
Human ST6Gal-I (β-galactoside α-2,6-sialyltransferase 1) is a member of the CAZy family GT29.
Application
α-2,6-Sialyltransferase from Photobacterium damsela has been used in resialylation and restoration of sialic acids (SAs) in HRT-18G cells.
Highly active α2-6 sialyltransferase has been used to prepare high levels of disialylated fragment crystals.
Actions biochimiques/physiologiques
The terminal step of complex N-glycan biosynthesis is catalysed by α-2,6-sialyltransferase (STs). Bacterial α(2,6)-STs possesses broader acceptor substrate specificity when compared to eukaryotic α(2,6)-STs.
Sialyltransferase transfers Neu5Ac from CMP-Neu5Ac to the galactosyl terminus of acceptor molecules including glycoproteins, glycolipids, and oligosaccharides.
Définition de l'unité
One unit will catalyze the formation of 1 μmol Neu-5-Ac-α-2,6-LacMU from CMP-Neu-5-Ac and Lac-β−OMU per minute at 37 °C at pH 8.0.
Forme physique
Supplied as a lyophilized powder containing Tris-HCl and NaCl.
Remarque sur l'analyse
Enzymatic activity assays are performed in Tris-HCl buffer (100 mM, pH 8.0) containing CMP-Neu-5-Ac (1 mM) and Lac-β−OMU (1 mM) at 37 °C for 30 min and analyzed using HPLC with a fluorescence detector (excitation at 325 nm and emission at 372 nm).

The terminal carbohydrate residues of the N-glycan on the immunoglobulin G (IgG) fragment crystallizable (Fc) determine whether IgG activates pro- or anti-inflammatory receptors. The IgG Fc alone becomes potently anti-inflammatory upon addition of α2-6-linked N-acetylneuraminic acid residues to the N-glycan
