WIKIMEDIA COMMONS, Michael Gäbler A few degrees difference in a single hydrogen bond angle prevents bacteria from importing arsenate in place of phosphate, a molecule integral to energy production, ...

The bacteria, a member of the genus Halomonadaceae, live in California's Mono Lake, amidst concentrations of arsenic that would kill most other life forms.

The arsenate-grown cells were analyzed in their resting phase, which requires less phosphate for survival than does active growth, notes Joyce, and cells grown in high concentrations of arsenate ...

The phosphate ion, PO 4 3-, plays several essential roles in cells: it maintains the structure of DNA and RNA, ... Arsenate forms much weaker bonds in water than phosphate, ...
