Genetic code flexibility in microorganisms: novel mechanisms and impact on physiology

Open access
Ling, Jiqiang, O'Donoghue, Patrick, Söll, Dieter·2015·Nature Reviews Microbiology

Abstract

The genetic code, initially thought to be universal and immutable, is now known to contain many variations, including biased codon usage, codon reassignment, ambiguous decoding and recoding. As a result of recent advances in the areas of genome sequencing, biochemistry, bioinformatics and structural biology, our understanding of genetic code flexibility has advanced substantially in the past decade. In this Review, we highlight the prevalence, evolution and mechanistic basis of genetic code variations in microorganisms, and we discuss how this flexibility of the genetic code affects microbial physiology.

  • Many deviations from the universal code exist, particularly in organelles and prokaryotes with small genomes.

    “Although many deviations from the universal code exist, particularly in organelles and prokaryotes with small genomes”

    From Origin and Evolution of the Universal Genetic Code (2017) · cites this paper as [47]

    The introductory passage in the Abstract section describes many deviations from the standard code, including yeast mitochondria and bacteria and archaea. It does not establish that deviations are particularly common in prokaryotes with small genomes; searches for “small genomes” and “reduced genome” found no passage making that connection. Page numbers were not available in our copy. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Limited deviations from the standard genetic code have been detected in many groups, particularly organelles and parasitic or endosymbiotic bacteria with highly reduced genomes.

    “The genetic code is nearly universal in all extant life forms although limited deviations from the SGC have been detected in many groups of organisms, particularly in organelles and parasitic or endosymbiotic bacteria with highly reduced genomes [11,16,17].”

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.
