Application of 92420-89-8, An article , which mentions 92420-89-8, molecular formula is C15H18Cl3NO10. The compound – (2S,3S,4S,5R,6R)-2-(Methoxycarbonyl)-6-(2,2,2-trichloro-1-iminoethoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate played an important role in people’s production and life.
Betaglycan, also known as TGF-beta type III receptor, is a membrane-anchored proteoglycan, which has two glycosaminoglycan (GAG) attachment sites (Lo?pez-Casillas, F.; Payne, H. M.; Andres, J. L.; Massague?, J. J. Cell Biol. 1994, 124, 557-568). Chondroitin sulfate (CS) or heparan sulfate (HS) can attach to the first site, Ser535, whereas only CS attaches to the second, Ser546. Although the mechanism behind the assembly of CS and HS is not fully understood, it has been reported that the assembly of HS requires not only a cluster of acidic residues but also hydrophobic residues located near the Ser-Gly attachment sites (Esko, J. D. Zhang, L. Curr. Opin. Struct. Biol. 1996, 6, 663-670). To further understand the effects of amino acids close to the Ser residues of the GAG-attachment sites on the glycosyltransferases, two tetraosyl peptides derived from the CS attachment sites of betaglycan, GlcA-Gal-Gal-Xyl-SerGlyAspAsnGly (1) and GlcA-Gal-Gal-Xyl-SerGlyAspAsnGlyPheProGly (2), were synthesized, and used as donor substrates for beta1,4-N-acetylgalactosaminyltransferase-I (beta4GalNAcT-I) and alpha1,4-N-acetylglucosaminyltransferase-I (alpha4GlcNAcT-I). Both the chemically synthesized linkage region tetrasaccharides were far better acceptors for beta4GalNAcT-I than for alpha4GlcNAcT-I in vitro, although they also showed appreciable acceptor activity for alpha4GlcNAcT-I.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 92420-89-8, help many people in the next few years., Application of 92420-89-8
