Abstract

Selenocysteine (Sec or U) is encoded by UGA, a stop codon reassigned by a Sec‐specific elongation factor and a distinctive RNA structure. To discover possible code variations in extant organisms we analyzed 6.4 trillion base pairs of metagenomic sequences and 24 903 microbial genomes for tRNA Sec species. As expected, UGA is the predominant Sec codon in use. We also found tRNA Sec species that recognize the stop codons UAG and UAA, and ten sense codons. Selenoprotein synthesis programmed by UAG in Geodermatophilus and Blastococcus, and by the Cys codon UGU in Aeromonas salmonicida was confirmed by metabolic labeling with 75 Se or mass spectrometry. Other tRNA Sec species with different anticodons enabled E. coli to synthesize active formate dehydrogenase H, a selenoenzyme. This illustrates the ease by which the genetic code may evolve new coding schemes, possibly aiding organisms to adapt to changing environments, and show the genetic code is much more flexible than previously thought.

  • Selenocysteine is represented in varying sets of proteins in diverse organisms from all three domains of life.

    “selenocysteine, which is represented in varying sets of proteins in diverse organisms from all three domains of life (3, 55)”

    From Origin and Evolution of the Universal Genetic Code (2017) · cites this paper as [55]

  • Selenocysteine and pyrrolysine have been co-opted into the code.

    “At least two well-characterized non-canonical amino acids have been co-opted into the code, namely, selenocysteine that is represented in varying sets of proteins in diverse organisms from all three domains of life [18,19], and pyrrolysine, currently detected only in some archaea.”

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.
