@mikewick77: Nitric oxide

One of the most common forms of protein modification is N-linked glycosylation, in which a high mannose core is attached to the amide nitrogen of asparagine.

Viruses use this host cell process to modify proteins present on their surface, which ultimately impacts the role of the viral glycoproteins in stability, antigenicity and host cell invasion.
