The effect of organic cosolvents on the oxygen affinity of fetal hemoglobin. Relevance of protein-solvent interactions to the functional properties

Autor: V, Militello, E, Vitrano, A, Cupane

Publikováno v: Biophysical chemistry. 39(2)

We have studied the effects of organic cosolvents (monohydric alcohols and formamide) on the oxygen affinity of human fetal hemoglobin stripped of phosphates and have compared them with the effects of the same cosolvents on the oxygen affinity of hum

Concentrated deionized solutions of hemoglobin in water were diluted with unbuffered pure /sup 2/H/sub 2/O and left to stand for 15 to 70 hrs Oxygen equilibrium curves were measured at different temperatures and concentrations of / sup 2/H/sub 2/O. I

Publikováno v: Nucleic acids research. 8(18)

This is a study of the effect of total and partial deuteration of solvent on critical temperatures and profiles of all four reactions occurring in poly(A) x n poly(U) (n = 1 or 2) aqueous systems. The study was done at observational times not longer
