A mutation in the human immunodeficiency virus type 1 transmembrane glycoprotein gp41 dominantly interferes with fusion and infectivity.

Abstract excerpt

Several domains of the human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein have been identified that are involved in HIV-1-mediated membrane fusion. One domain that is involved in membrane fusion is the hydrophobic amino terminus of the HIV-1 transmembrane glycoprotein gp41. Here we show that a polar substitution at gp41 amino acid 2 (the 41.2 mutation) results in an envelope glycoprotein that...
