Descripción general

Human ST6Gal-I (β-galactoside α-2,6-sialyltransferase 1) is a member of the CAZy family GT29.

Aplicación

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.

Acciones bioquímicas o fisiológicas

Sialyltransferase transfers Neu5Ac from CMP-Neu5Ac to the galactosyl terminus of acceptor molecules including glycoproteins, glycolipids, and oligosaccharides.
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.

Definición de unidad

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.

Forma física

Supplied as a lyophilized powder containing Tris-HCl and NaCl.

Nota de análisis

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).

Human influenza viruses are major concern as the leading cause of global pandemics. In infecting cells, they preferentially bind to sialyloligosaccharides containing terminal N-acetyl sialic acid linked to galactose by an α-2,6-linkage (NeuAcα2,6Gal). The amount of NeuAcα2,6Gal in Vero cells

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
