| Application: | Galactosyltransferase from bovine milk has been used: • in the generation of hyper-galactosylated variant of IgG1 • in β -1,4-galactosyltransferas • in the modification of LacNAcQ11 and LacDiNAcQ11 nanofibers |
| Application: | Galactosyltransferase is the catalytic component of the lactose synthetase system; it synthesizes lactose slowly in the absence of the regulatory protein α-lactalbumin. Galactosyltransferase will also transfer galactose from UDP-galactose to N-acetylglucosamine. This preparation is useful in the determination of α-lactalbumin, UDP-galactose, and N-acetylglucosamine. |
| Biochem/physiol Actions: | Galactosyltransferase catalyzes the transfer of galactosyl molecules in the synthesis of oligosaccharides. |
| Biochem/physiol Actions: | Galactosyltransferase from bovine milk requires Mn2+ ions for its catalytic functionality. Alteration in the galactosyltransferase levels have been implicated in various disease states.Galactosyltransferase(Gal |
