From: A new family of periplasmic-binding proteins that sense arsenic oxyanions
Binding thermodynamics of AioX, ArxX and ArrX with their respective substrates. Upper panels: raw thermograms; lower panels: integrated binding isotherms. (A) AioX with arsenite; (B) ArxX with arsenite; (C) ArrX with arsenate; (D) ArrX with phosphate; (E) Thermodynamic parameters of substrate binding at 25 °C, values represent mean and standard deviation of three experiments, N: stoichiometry; Kd: dissociation constant; ΔH: enthalpy change; ΔS: entropy change.
