Role of Neuraminidase in Influenza A(H7N9) Virus Receptor Binding

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.
