Reversible reaction of 5,5V-dithiobis(2-nitrobenzoate) with the hemoglobins of the domestic cat: Acetylation of NH3 terminal group of the h chain transforms the complex pH dependence of the forward apparent second order rate constant to a simple form
We demonstrate kinetically that the reaction of 5,5V-dithiobis(2-nitrobenzoate) with the CysF9[93]h sulfhydryl group of domestic cat
hemoglobins is a reversible process. In the major hemoglobin, in which the NH3
+ terminal group of GlyNA1[1]h is free, kf, the apparent
forward second order rate constant, has a complex pH dependence profile. In the minor hemoglobin, the NH3
+ terminal group...
