Structural and Functional Analysis of Interhelical Interactions in the Human Immunodeficiency Virus Type 1 gp41 Envelope Glycoprotein by Alanine-Scanning Mutagenesis

15 Nov 2001

Abstract excerpt

Membrane fusion by human immunodeficiency virus type 1 (HIV-1) is promoted by the refolding of the viral envelope glycoprotein into a fusion-active conformation. The structure of the gp41 ectodomain core in its fusion-active state is a trimer of hairpins in which three antiparallel carboxyl-terminal helices pack into hydrophobic grooves on the surface of an amino-terminal trimeric coiled coil. In an effort to...
