General description

Calorimetry studies show that the two lectin-like domains flanking the central catalytic domain of Neuraminidase serve as the recognition and binding sites for sialic acid-containing substrates.
Neuraminidase enzymes are hydrolase enzymes that promote influenza virus release from infected cells and facilitate virus spread.

Application

Neuraminidase from Vibrio cholera has been used in a study to describe a five-step purification method. It has also been used in a study to investigate modification of leukemia L1210 tumor cells.
Neurminidase is used as a cell-surface probe for glycoconjugate distribution and in substrate specificity studies.

Physical form

Solution in 50 mM sodium acetate, pH 5.5, containing 0.15 M sodium chloride and 4 mM calcium chloride, 0.2 μm filtered..

Preparation Note

A further purification by affinity chromatography of our Type III.

Analysis Note

Preservative free.

Other Notes

One unit will liberate 1.0 μmole of N-acetylneuraminic acid per min at pH 5.0 at 37 °C using NAN-lactose or bovine submaxillary mucin, unless otherwise specified. Prices based on units using NAN-lactose as substrate.

Vibrio cholerae neuraminidase is part of a mucinase complex which may function in pathogenesis by degrading the mucin layer of the gastrointestinal tract. The neuraminidase, which has been the target of extensive inhibitor studies, plays a subtle role in the
