Results of fitting arsenic K-edge EXAFS of GFAJ-1. S02 = 1, global amplitude factor and E0 = 13.97, offset for calibration. Type, the coordination type; Number, the coordination number; R, interatomic distance; and σ2, the measure of the static disorder of the shell. See table S2 for comparison to P in P-containing biomolecules (11).
