N1 Neuraminidase

N1 neuraminidase is an enzyme found on the surface of influenza viruses, specifically on certain strains like H1N1. Its main role is to help the virus spread within the human body by cleaving sialic acid molecules on the surface of infected cells and mucus. This action allows new virus particles to detach and infect other cells more easily. Because of its crucial function, N1 neuraminidase is also a target for antiviral drugs, which inhibit its activity to stop the virus from spreading, helping to treat influenza infections effectively.
