Abstract

Membrane transport constitutes one of the most fundamental processes in all living cells with proteins as major players. Proteins as channels provide highly selective diffusive pathways gated by environmental factors, and as transporters furnish directed, energetically uphill transport consuming energy. X-ray crystallography of channels and transporters furnishes a rapidly growing number of atomic resolution structures, permitting molecular dynamics (MD) simulations to reveal the physical mechanisms underlying channel and transporter function. Ever increasing computational power today permits simulations stretching up to 1 μsec, i.e., to physiologically relevant time scales. Membrane protein simulations presently focus on ion channels, on aquaporins, on protein-conducting channels, as well as on various transporters. In this review we summarize recent developments in this rapidly evolving field.

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.
