Mutational analysis of conserved N-linked glycosylation sites of human immunodeficiency virus type 1 gp41

J Virol. 1992 Mar;66(3):1799-803. doi: 10.1128/JVI.66.3.1799-1803.1992.

Abstract

Amino acid substitutions were introduced into four conserved N-linked glycosylation sites of the human immunodeficiency virus type 1 envelope transmembrane glycoprotein, gp41, to alter the canonical N-linked glycosylation sequences. One altered site produced a severe impairment of viral infectivity, which raises the possibility that N-linked sugars at this site may have an important role in the human immunodeficiency virus type 1 life cycle.
