Abstract

Autotransport in Gram-negative bacteria denotes the ability of surface-localized proteins to cross the outer membrane (OM) autonomously. Autotransporters perform this task with the help of a β-barrel transmembrane domain localized in the OM. Different classes of autotransporters have been investigated in detail in recent years; classical monomeric but also trimeric autotransporters comprise many important bacterial virulence factors. So do the two-partner secretion systems, which are a special case as the transported protein resides on a different polypeptide chain than the transporter. Despite the great interest in these proteins, the exact mechanism of the transport process remains elusive. Moreover, different periplasmic and OM factors have been identified that play a role in the translocation, making the term 'autotransport' debatable. In this review, we compile the wealth of details known on the mechanism of single autotransporters from different classes and organisms, and put them into a bigger perspective. We also discuss recently discovered or rediscovered classes of autotransporters.

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

  • The autotransporter family of Gram-negative bacteria is particularly rich in autoagglutinins.

    “A class of proteins that is particularly rich in autoagglutinins is the autotransporter family of Gram-negative bacteria [66].”

    From Bacterial autoaggregation (2018) · cites this paper as [66]

    The Type Vc secretion section says trimeric autotransporters in Gram-negative pathogens are usually adhesins, but it does not say they cause bacterial autoagglutination. Searches for autoagglutinins, autoaggregation, and cell–cell adhesion found no passage establishing that the autotransporter family is particularly rich in autoagglutinins. The indexed copy provides no page number for these passages. (LLM, conf=0.72)

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.
