| Method | calculated from the equation: delta G (Phos) = delta G (at standard conditions) + RT ln([ATP]/[ADP][Pi]), where R is the gas constant, T = temperature, and -30.5 kJ/mol was used for delta G at standard conditions. |
| Comments | The number has been converted from positive to negative so that it describes the Gibbs free energy of hydrolysis as opposed to the phosphorylation potential. The E. coli was growing in the presence of oxygen. See reference for more details. |
