Activity summary

Neuraminidase sometimes called sialidase functions as an enzyme that cleaves sialic acid residues from glycoproteins and glycolipids. This process is essential for the maturation and release of progeny viruses from infected cells. Enzymatically active neuraminidase proteins weigh about 60 kilodaltons and localize on the surface of influenza viruses. Researchers identify its expression on the viral envelope playing a pivotal role in the viral life cycle. Neuraminidase activity is an important target for drug development against influenza.

Biological function summary

Neuraminidase significantly impacts viral virulence and host cell infection. It is part of the functional machinery required for viral particle detachment from the host cell membrane facilitating the spread of infection. Neuraminidase works alongside other viral proteins including hemagglutinin which attaches the virus to the host cell. The neuraminidase function of trimming sialic acids is critical in the ongoing interaction between virus and host.

Pathways

The influenza lifecycle heavily involves neuraminidase-mediated sialic acid cleavage. This enzyme contributes to pathways by enabling the efficient release of new viral particles enhancing the infectivity of the virus. Neuraminidase operates in concert with hemagglutinin which initially binds the virus to host cells by attaching to the sialic acid residues. This interplay is vital in viral replication pathways which propagate the infection cycle.

Associated diseases and disorders

Influenza directly relates to neuraminidase as it is a primary means by which the virus spreads within the host. Neuraminidase inhibitors are a class of antiviral drugs that target this protein important for treating and managing influenza infections. Besides influenza research links neuraminidase activity to bacterial infections with some bacterial neuraminidases implicated in the pathogenesis of diseases like pneumonia. The relationship to hemagglutinin in viral influenza highlights the significance of neuraminidase as a target in therapeutic interventions.
