Viral neuraminidase

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 re

Hemagglutinin-neuraminidase refers to a single viral protein that has both hemagglutinin and neuraminidase EC 3.2.1.18 activity. This is in contrast to the proteins found in influenza, where both func

…and prevents self-aggregation. Neuraminadase also facilitates the movement of virus particles in the presence of mucus rich in sialic acid. A single hemagglutinin-neuraminidase protein can combine neuraminidase and hemagglutinin functions, such as in mumps virus and human parainfluenza virus. The enzyme helps viruses to be…
