Reversible reaction of 5,5′-dithiobis(2-nitrobenzoate) with the CysF9[93]β sulfhydryl groups of the hemoglobins of the domestic cat: Variation of the equilibrium and reverse rate constants with pH
We have determined for the first time the equilibrium constant, Keq, for the reaction of Ellman's reagent, 5,5′-dithiobis(2-nitrobenzoate),
with the CysF9[93]β sulfhydryl groups of the hemoglobins of the domestic cat. In the pH range 5.6 to 9.0 Kequ varies over four orders of
magnitude — between ca 10 and 10−3 — for all hemoglobin derivatives. Using these Kequ values and published...
