Bacterial serine proteases secreted by the autotransporter pathway: classification, specificity, and role in virulence

Abstract

Serine proteases exist in eukaryotic and prokaryotic organisms and have emerged during evolution as the most abundant and functionally diverse group. In Gram-negative bacteria, there is a growing family of high molecular weight serine proteases secreted to the external milieu by a fascinating and widely employed bacterial secretion mechanism, known as the autotransporter pathway. They were initially found in Neisseria, Shigella, and pathogenic Escherichia coli, but have now also been identified in Citrobacter rodentium, Salmonella, and Edwardsiella species. Here, we focus on proteins belonging to the serine protease autotransporter of Enterobacteriaceae (SPATEs) family. Recent findings regarding the predilection of serine proteases to host intracellular or extracellular protein-substrates involved in numerous biological functions, such as those implicated in cytoskeleton stability, autophagy or innate and adaptive immunity, have helped provide a better understanding of SPATEs' contributions in pathogenesis. Here, we discuss their classification, substrate specificity, and potential roles in pathogenesis.

  • Class-1 serine protease autotransporters from enterobacteriaceae target intracellular substrates, eliciting cytotoxic and endotoxin effects on the host.

    “Class-1 SPATEs target intracellular substrates, eliciting cytotoxic and endotoxin effects on the host.67”
  • Serine protease autotransporters from enterobacteriaceae degrade host intracellular or extracellular substrates, which trigger a variety of adverse effects on host cells.

    “Several findings suggest that SPATEs degrade host intracellular or extracellular substrates, which trigger a variety of adverse effects on host cells.67”

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.
