Abundance of 4Fe–4S motifs in the genomes of methanogens and other prokaryotes

Major, Tiffany A., Burd, Henry, Whitman, William B.·2004·FEMS Microbiology Letters

Abstract

The abundance of 4Fe-4S motifs of the form CX2CX2CX3C was analyzed in the open reading frames (ORFs) of 120 prokaryotic genomes. The abundance of ORFs containing the CX2CX2CX3C motif or isORFs correlated (r=0.82) with methanogenesis (p=0.0001), archaea (p=0.0173), anaerobiosis (p<0.0001) and genome size (p<0.0001). Optimal growth temperature (hyperthermophily) did not correlate with the number of isORFs (p=0.6283). Large numbers of CX2CX2CX3C motifs may be associated with unique physiologies: methanogenic archaea contained the greatest number of CX2CX2CX3C motifs found among the prokaryotic groups; however, only about 15% of the motifs were in genes directly involved in methanogenesis. Large numbers of CX2CX2CX3C motifs may also be associated with generalists such as Desulfitobacterium hafniense, which is an anaerobic bacterium containing multiple reductases.

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.
