The three‐dimensional structure of porin from Rhodobacter capsulatus at 3 Å resolution
Open accessAbstract
The crystal structure of porin from Rhodobacter capsulatus strain 37b4 has been solved at 3.0 Å (1 Å = 0.1 nm) resolution by multiple isomorphous replacement and solvent‐flattening. The three pores of the trimer are well denned in the electron density map. Each pore consists of a 16‐stranded β‐barrel which traverses the membrane as a tube. Near its center the tube is narrowed by chain segments protruding from the inner wall of the barrel that form an eye‐let with an irregular cross‐section of about 6 Å by 10 Å. The eye‐let has an axial length of about 10 Å; it defines the exclusion limit for diffusing particles.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
