Native Vibrio cholerae Neuraminidase
Cat No.
NATE-0481
Description
Neuraminidase enzymes are glycoside hydrolase enzymes (EC 3.2.1.18) that cleave the glycosidic linkages of neuraminic acids. Neuraminidase enzymes are a large family, found in a range of organisms. The best-known neuraminidase is the viral neuraminidase, a drug target for the prevention of the spread of influenza infection. The viral neuraminidases are frequently used as antigenic determinants found on the surface of the Influenza virus. Some variants of the influenza neuraminidase confer more virulence to the virus than others. Other homologs are found in mammalian cells, which have a range of functions. At least four mammalian sialidase homologs have been described in the human genome (see NEU1, NEU2, NEU3, NEU4).
Abbr
Neuraminidase, Native (Vibrio cholerae)
Alias
sialidase
Source
Vibrio cholerae
Applications
Neurminidase is used as a cell-surface probe for glyc oconjugate distribution and in substrate specificity studies. Neuraminidase from Vibrio cholerae has been used in a study to assess its role in the binding and uptake of cholera toxin by susceptible cells. It has also been used in a study to investigate the preparation of a sodium substrate and its use in a fluorometric assay of neuraminidase.
Product Overview
Neuraminidase enzymes are glycoside hydrolase enzymes that catalyze hydrolysis of terminal sialic acid residues. The most well-known are the viral nearamidases, which promote influenza virus release.
