Abstract

First-principles simulations start to be applicable to the photochemistry and photophysics in biological systems. In this review the prerequisites for investigating such excited state phenomena in large systems are outlined. Generally, a quantum mechanical description of the electronic structure is combined with molecular dynamics simulations, which allows to describe the motion of the atoms in the field produced by the quantum-mechanical potential. Like this, bonds can be formed and broken, that is, chemical reactions can be simulated. The review focuses on applications of first-principles molecular dynamics to photoactive proteins.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In bacteria, opsins act as pumps for cations and anions.

    “in bacteria they function as cation and anion pumps,217−223”

    From Chemistry of the Retinoid (Visual) Cycle (2014) · cites this paper as [221]

    Section 4.4, “Bacteriorhodopsin” (page unavailable), describes bacteriorhodopsin as a light-driven pump that transports protons, which are cations, across a cell membrane. It does not describe anion pumping, so it supports only the cation part of the claim. (LLM, conf=0.88)

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.
