Galacto-N-biose, a component of the galacto-N-biose/lacto-N-biose metabolic pathway, is used as a substrate to identify, differentiate and characterize enzymes such as N-acetylglucosaminyltransferase(s), fucosyl- and sialyltransferase(s), galactosidase(s) and galacto-N-biose/lacto-N-biose I phosphorylase(s) (GLNBP). Galacto-N-biose is used in lectin inhibition studies.


A substrate for N-acetylglucosaminyltransferase, fucosyl- and sialyltransferase, and galactosidase. Also used in lectin inhibition studies.

We have examined the carbohydrate binding specificity of the B4 lectin from Vicia villosa seeds. The B4 lectin agglutinates Tn-exposed erythrocytes specifically and binds to these erythrocytes (1.4 X 10(6) sites/cell) with an association constant of 4.2 X 10(7) M-1.

The preceding paper (Williams, D., and Schachter, H. (1980) J. Biol. Chem. 255, 0000-0000) described a novel N-acetylglucosaminyltransferase in canine submaxillary gland microsomes which catalyzed the incorporation of GlcNAc into mucin acceptors. We show in the present report that the

The acceptor substrate specificity and kinetic properties of the purified porcine submaxillary beta-galactoside alpha 1 leads to 2 fucosyltransferase have been examined. The transferase forms the Fuc alpha 1 leads to 2Gal linkage with oligosaccharides, glycoproteins, and glycolipids which contain

The substrate requirements, linkage specificity, and kinetic mechanism of a pure sialyltransferase from porcine submaxillary glands have been examined. The enzyme transfers sialic acid from the donor nucleotide, CMP-NeuAc, into the sequence NeuAcalpha2 leads to 3Galbeta1 leads to 3GalNAc, which

Ligation of tumor necrosis factor receptor 1 (TNFR1) can cause cell death by caspase 8 or receptor-interacting protein kinase 1 (RIPK1)- and RIPK3-dependent mechanisms. It has been assumed that because RIPK1 bears a death domain (DD), but RIPK3 does not


Review of O-Linked Glycoproteins

O-Linked glycoproteins are usually large proteins with a molecular mass of >200 kDa. Glycosylation generally occurs in high-density clusters and may represent as much as 50-80% of the overall mass.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
