ABSTRACT The coiled-coil region of the human immunodeficiency virus type 1 transmembrane protein (gp41) makes up the interior core of the six-helix bundle structure of the gp41 self-assembly domain. We extended our previous study of this domain (Y. Weng and C. D. Weiss, J. Virol. 72:9676–9682, 1998) by analyzing 23 additional mutants at positions that lie at the interface of the interior core and outer helices. We found nine new functional mutants. For most mutants, the activity could be explained by the ability of the modeled mutants to stabilize the six-helix bundle structure. The present study provides insights into the envelope glycoprotein fusion mechanism and information for rational drug and vaccine design.

ABSTRACT Two heptad repeat regions in the ectodomain of the human immunodeficiency virus type 1 (HIV-1) transmembrane subunit (gp41) self-assemble into a six-helix bundle structure that is critical for virus entry. Immunizations with peptides corresponding to these regions generated antibodies specific to the receptor-activated conformations of gp41.
