Abstract Uptake of nucleobases and ascorbate is an essential process in all living organisms mediated by SLC23 transport proteins. These transmembrane carriers operate via the elevator alternating-access mechanism, and are composed of two rigid domai

Lateral opening of the LptDE transporter in the outer membrane of Gram-negative bacteria is necessary for insertion of lipopolysaccharides. Here, Botte et al. report a cryo-EM structure of a partially opened LptDE transporter, in complex with rigid c

ABC exporters hydrolyze ATP to pump substrates across membranes, but critical steps of the transport mechanism remain poorly understood. Here, the authors solve the crystal structure of outward-facing TM287/288 with the help of a state-specific sybod

Summary: Iodide migration causes degradation of the perovskite solar cells. Here, we observe the direct migration of iodide into the hole-transport layer in a device. We demonstrate that ultrathin room temperature atomic layer-deposited Al2O3 on the

Mechanistic and structural studies of membrane proteins require their stabilization in specific conformations. Single domain antibodies are potent reagents for this purpose, but their generation relies on immunizations, which impedes selections in th

The isostructural title compounds, {(C7H7N2)2[SnI4]}n, (1), and {(C7H5F2N2)2[SnI4]}n, (2), show a layered perovskite-type structure composed of anionic {[SnI4]2−}n sheets parallel to (100), which are decorated on both sides with templating benzimid

Pentameric ligand-gated ion channels are activated by the binding of agonists to a site distant from the ion conduction path. These membrane proteins consist of distinct ligand-binding and pore domains that interact via an extended interface. Here, w
