Crystal structures of APOBEC3G N-domain alone and its complex with DNA

Abstract

The N-terminal domain of APOBEC3G (A3G) is required for anti-HIV activity, HIV-1 viral infectivity factor (Vif) binds to this domain of A3G to mediate its degradation. Here, the authors use their crystal structures of this A3G domain alone and bound to single-stranded DNA to investigate the molecular details of this interaction.
