The evolutionary history of the genes involved in the biosynthesis of the antioxidant ergothioneine

Jones, Gary W., Doyle, Sean, Fitzpatrick, David A.·2014·Gene

Abstract

Ergothioneine (EGT) is a histidine betaine derivative that exhibits antioxidant action in humans. EGT is primarily synthesized by fungal species and a number of bacterial species. A five-gene cluster (egtA, egtB, egtC, egtD &egtE) responsible for EGT production in Mycobacteria smegmatis has recently been identified. The first fungal biosynthetic EGT gene (NcEgt-1) has also been identified in Neurospora crassa. NcEgt-1 contains domains similar to those found in M. smegmatis egtB and egtD. EGT is biomembrane impermeable. Here we inferred the evolutionary history of the EGT cluster in prokaryotes as well as examining the phyletic distribution of Egt-1 in the fungal kingdom. A genomic survey of 2509 prokaryotes showed that the five-gene EGT cluster is only found in the Actinobacteria. Our survey identified more than 400 diverse prokaryotes that contain genetically linked orthologs of egtB and egtD. Phylogenetic analyses of Egt proteins show a complex evolutionary history and multiple incidences of horizontal gene transfer. Our analysis also identified two independent incidences of a fusion event of egtB and egtD in bacterial species. A genomic survey of over 100 fungal genomes shows that Egt-1 is found in all fungal phyla, except species that belong to the Saccharomycotina subphylum. This analysis provides a comprehensive analysis of the distribution of the key genes involved in the synthesis of EGT in prokaryotes and fungi. Our phylogenetic inferences illuminate the complex evolutionary history of the genes involved in EGT synthesis in prokaryotes. The potential to synthesize EGT is a fungal trait except for species belonging to the Saccharomycotina subphylum.

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

  • ERG is synthesised by a variety of microbes, especially fungi and actinobacteria.

    “The chief organisms capable of its synthesis are fungi and certain yeasts(59,60), though actinobacteria and certain other micro-organisms(60–66), including the slime mould Physarum polycephalum (65), cyanobacteria(67–71) and methylotrophs(72) are also naturally capable of its production.”

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.
