Effect of Organic Phosphates on the Sulfhydryl Reactivities of Oxyhemoglobins A and S*
The /393 sulfhydryl groups of oxyhemoglobins A and
S display a difference in reactivity with 5,5’-dithiobis-
2-nitrobenzoic acid. It is concluded that this difference
arises from differences in tertiary structure in the vicinity
of the p”“ site.
Organic phosphatesd ecrease the pg3s ulfhydryl reactivity.
We have used this effect to measure the organic
phosphate binding constants....
