A Bacterium That Can Grow by Using Arsenic Instead of Phosphorus
http://www.sciencemag.org/content/early/2010/12/01/science.1197258#aff-5
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, which substitutes 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 bioelements may have profound evolutionary and
geochemical significance.
有微生物可以用As取代P在macromolecules的组成
真的是个很惊人的发现... (虽然我只看abstract)
有人说可以挑战诺贝尔 我也觉得可能没几年後就得奖了吧!!
有念博班的有没有要在seminar报一下这篇的啊~XD
