Env’s transmembrane domain revealed HIV-1’s envelope protein (Env) spans the viral membrane and grants the virus entry into host cells. Env is also the sole protein of HIV-1 that is targeted by antibodies, making it a key target for vaccine design. Dev et al. used nuclear magnetic resonance to determine an atomic-level structure of the membrane-spanning region of Env in a lipid bicelle. Env’s t...
We report the first directed adsorption of Photosystem I (PSI) on patterned surfaces containing discrete regions of methyl- and hydroxyl-terminated self-assembled monolayers (SAMs) on gold. SAM and PSI patterns are characterized by scanning electrochemical microscopy (SECM). The insulating protein complex layer blocks the electron transfer of the SECM mediator, thereby reducing the electrochemi...
We report the fabrication of a hybrid light-harvesting electrode consisting of photosystem I (PSI) proteins extracted from spinach and adsorbed as a monolayer onto electrically contacted, large-area graphene. The transparency of graphene supports the choice of an opaque mediator at elevated concentrations. For example, we report a photocurrent of 550 nA/cm(2) from a monolayer of PSI on graphene...
