Abstract

Life is mostly composed of the elements carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus. Although these six elements make up nucleic acids, proteins, and lipids and thus the bulk of living matter, it is theoretically possible that some other elements in the periodic table could serve the same functions. Here, we describe a bacterium, strain GFAJ-1 of the Halomonadaceae, isolated from Mono Lake, California, that is able to substitute arsenic for phosphorus to sustain its growth. Our data show evidence for arsenate in macromolecules that normally contain phosphate, most notably nucleic acids and proteins. Exchange of one of the major bio-elements may have profound evolutionary and geochemical importance.

Score in context

This research output has an Altmetric score of 1002. This is our high-level measure of the quality and quantity of online attention that it has received. This score was calculated when the research output was last mentioned on 24 October 2015.
All research outputs
#493
of 4,724,476 outputs
Outputs from Science
#35
of 30,832 outputs
Outputs of similar age
#475
of 3,661,553 outputs
Outputs of similar age from Science
#35
of 27,274 outputs
Altmetric has tracked 4,724,476 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 30,832 research outputs from this source. They typically receive a lot more attention than average, with a mean score of 26.5. This one has done particularly well, scoring higher than 99% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this score to the 3,661,553 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 27,274 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 99% of its contemporaries.
