The interaction between influenza virus hemagglutinin and its cell-surface receptor, 5-N-acetylneuraminic acid (sialic acid), was probed by the synthesis of 12 sialic acid analogs, including derivatives at the 2-carboxylate, 5-acetamido, 4-, 7-, and 9-hydroxyl, and glycosidic positions.

Sialinsyra - Sialic acid. Från Wikipedia, den fria encyklopedin. Sialinsyror är en klass av alfa-keto-syrasockerarter med en nio kol ryggrad. Termen "sialinsyra" Sialic acid linked to glycoproteins and gangliosides is used by many viruses as a receptor for cell entry. These viruses include important human and animal pathogens, such as influenza, parainfluenza, mumps, corona, noro, rota, and DNA tumor viruses. Sialic acid is synthesized by glucosamine 6 phosphate and acetyl-CoA through a transferase, resulting in N -acetylglucosamine-6-P. This becomes N -acetylmannosamine-6-P through epimerization, which reacts with phosphoenolpyruvate producing N -acetylneuraminic-9-P (sialic acid).

Sialic acid receptor

These viruses resemble influenza C viruses because they share not only the receptor determinant, but also the presence of an acetylesterase that releases the 9- O -acetyl group from sialic acid and thus abolishes the ability of the respective sialoglycoconjugate to function as a receptor for BCoV. The virus binds to the dipeptidyl peptidase 4 (DPP4) entry receptor on respiratory epithelial cells via its spike protein. We here report that the MERS-CoV spike protein selectively binds to sialic acid (Sia) and demonstrate that cell-surface sialoglycoconjugates can serve as an attachment factor. exhibit preferential binding to α2,6- and α2,3-linked sialic acids, respectively (11).

A novel epitope residing in the sialic acid receptor-bindingdomain of VEPGDKITFEATGNL (251-265) of the pandemic flu hemagglutinin wasidentified.

B-Lymphocyte Cell Adhesion Molecule. Initial attachment on cells through primary receptor binding is usually For example, influenza viruses bind to receptors containing sialic acid on the cell surface CONDENSED WORK PLAN: For identification of novel receptors, we plan to of cellular receptor distribution on cells and tissues, iv) that sialic acid containing In a series of publications, we have reported that this virus uses sialic acid as a cellular receptor.

2010-12-09 · It is commonly accepted that avian influenza viruses (AIVs) bind to terminal α2,3 sialic acid (SA) residues whereas human influenza viruses bind to α2,6 SA residues. By a series of amino acid changes on the HA surface protein, AIVs can switch receptor specificity and recognize α2,6 SA positive cells, including human respiratory epithelial cells. Animal species, like pigs and Japanese quail

2007-10-25 · Influenza virus binds to cell receptors via sialic acid (SA) linked glycoproteins. They recognize SA on host cells through their haemagglutinins (H). The distribution of SA on cell surfaces is one determinant of host tropism and understanding its expression on human cells and tissues is important for understanding influenza pathogenesis.

such as C-terminal lysine clipping, deamidation, glycation, sialic acid or Coxsackievirus A24 variant uses sialic acid-containing O-linked glycoconjugates as cellular receptors on human ocular cells.
