Inositol Hexakisphosphate Promotes Open Pore State in HIV Capsid Protein Lattice by Reconfiguring Subunit Contacts
The mature human immunodeficiency virus (HIV-1) capsid is composed of approximately 250 capsid protein hexamers, each containing a central pore delimited by a β-hairpin and an α-helix from each monomer. The cellular metabolite inositol hexakisphosphate (IP6) binds this pore and modulates translocation of nucleoside t...
