WebApr 19, 2010 · Viruses are divided into two groups: enveloped viruses are surrounded by an outer lipid membrane; nonenveloped viruses lack this membrane. Where present, the envelope contains the viral proteins, which mediate binding to host cells. Where no envelope is present, this function is carried out by the outer capsid proteins. Spikes typically have a role in viral entry. They may interact with cell-surface receptors located on the host cell and may have hemagglutinizing activity as a result, or in other cases they may be enzymes. For example, influenza virus has two surface proteins with these two functions, hemagglutinin and neuraminidase. The binding site for the cell-surface receptor is usually located at the tip of the spike. Many spike proteins are membrane fusion proteins. Being exposed on the su…

WebThe function of the spike glycoprotein is to mediate viral entry into the host cell by first interacting with molecules on the exterior cell surface and then fusing the viral and cellular membranes. Spike glycoprotein is a class I fusion protein that contains two regions, known as S1 and S2, responsible for these two functions.

WebA virus is a tiny, infectious particle that can reproduce only by infecting a host cell.
