Crystal structure, conformational fixation, and entry-related interactions of mature ligand-free HIV-1 Env
As the sole viral antigen on the HIV-1-virion surface, trimeric Env is a focus of vaccine efforts. Here we present the structure of the ligand-free HIV-1-Env trimer, fix its conformation, and determine its receptor interactions. Epitope analyses revealed trimeric ligand-free Env to be structurally c...
