Abstract

The secondary structure of the precursor (gp160) of the envelope protein of human immunodeficiency virus type 1 (BH10) and its receptor-binding subunit (gp120) was studied by Fourier-transformed attenuated total reflection spectroscopy. A higher alpha-helix/beta-sheet ratio in the gp120 subunit than in the precursor indicates a structural heterogeneity between the two subunits (gp120 and gp41), in agreement with classical secondary-structure predictions. The secondary structure of gp41 was estimated and compared with existing models. The high alpha-helical content in gp41 and the dominant beta-sheet content in gp120 resemble the distribution in influenza virus hemagglutinin subunits.
