Viral Neuraminidase (NA)

Target
NA
Molecular classification
Enzyme, Glycoprotein, Viral protein, Hydrolase
01

Overview

Viral neuraminidase is a surface glycoprotein enzyme found on the envelope of several viruses, most notably influenza viruses. It plays a critical role in the viral life cycle by facilitating the release and spread of progeny virions from infected host cells by cleaving terminal sialic acid residues.

Other names
SialidaseExo-alpha-sialidase
02

Mechanism of action

Competitive inhibition of neuraminidase activity by mimicking sialic acid structure, thereby limiting virus release and spread.
