The purpose of viral neuraminidase is

Viral neuraminidase is a type of neuraminidase found on the surface of influenza viruses that enables the virus to be released from the host cell. Neuraminidases are enzymes that cleave sialic acid (also called neuraminic acid) groups from glycoproteins. Neuraminidase inhibitors are antiviral agents that … Visa mer The enzyme helps viruses to be released after budding from the plasma membrane of a host cell. Influenza virus membranes contain two glycoproteins: hemagglutinin and neuraminidase. While the hemagglutinin on … Visa mer Neuraminidase has been targeted in structure-based enzyme inhibitor design programmes that have resulted in the production of two drugs, zanamivir (Relenza) and Visa mer Neuraminidase enzymes can have endo- or exo-glycosidase activity, and are classified as EC 3.2.1.29 (endo-neuraminidase) and EC 3.2.1.18 (exo-neuraminidases).
