Protein Design of a Bacterially Expressed HIV-1 gp41 Fusion Inhibitor

Abstract excerpt

Peptides derived from the carboxyl-terminal heptad repeat of the gp41 envelope glycoprotein ectodomain (C-peptides) can inhibit HIV-1 membrane fusion by binding to the amino-terminal trimeric coiled coil of the same protein. The fusion inhibitory peptide T-20 contains an additional tryptophan-rich sequence motif whose binding site extends beyond the gp41 coiled-coil region yet provides the key determinant of...
