Midpoint potentials of native and Met-loss form, collected at pH 6.0, 10°C. The listed value is the average of at least three trials and error is given as the standard deviation.
Midpoint potential (Em) was determined in pH 6.0 citrate + KPi, 30°C, plus 8M GdnHCl.
Midpoint potential (Em) was determined in pH 6.0 citrate/KPi, 10°C, 8M GdnHCl.
