Abstract

Escherichia coli was one of the first species to have its genome sequenced and remains one of the best-characterized model organisms. Thus, it is perhaps surprising that recent studies have shown that a substantial number of genes have been overlooked. Genes encoding more than 140 small proteins, defined as those containing 50 or fewer amino acids, have been identified in E. coli in the past 10 years, and there is substantial evidence indicating that many more remain to be discovered. This review covers the methods that have been successful in identifying small proteins and the short open reading frames that encode them. The small proteins that have been functionally characterized to date in this model organism are also discussed. It is hoped that the review, along with the associated databases of known as well as predicted but undetected small proteins, will aid in and provide a roadmap for the continued identification and characterization of these proteins in E. coli as well as other bacteria.

  • Growing experimental evidence in mycobacteria and other prokaryotes has shown that many sproteins are functional, requiring a rethinking of gene definitions.

    “However, growing experimental evidence in mycobacteria and other prokaryotes has shown that many sproteins are functional, requiring a rethinking of gene definitions (71–75).”

    From Mycobacterium smegmatis: The Vanguard of Mycobacterial Research (2023) · cites this paper as [75]

    The Functions of Small Proteins section (page unavailable) reports experimental results suggestive of functions for multiple E. coli small proteins, though it says relatively few have been characterized mechanistically. The Properties of Small Protein Genes and Small Proteins section recommends looking beyond conventional sequence characteristics when identifying them. The paper does not establish the claim specifically for mycobacteria or explicitly call for redefining genes. (LLM, conf=0.83)

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.
