Conservation, Compensation, and Evolution of  N-Linked Glycans in the HIV-1 Group M Subtypes and  Circulating Recombinant Forms

<table>Prevalence of glycosylation at selected positions. The relative frequency of glycosylation between subtypes/CRFs at positions where at least one subtype/CRFs shows high levels of glycosylation.  Positions where greater than 75% of sequences were predicted as glycosylated for at least one subtype/CRF are shown.</table>
