  • Title: [Kinetics of the reaction of hemoglobin with carbon monoxide. I. Relaxation measurements during photolytic illumination].
    Author: Ermakov IuA, Pasechnik VI.
    Journal: Biofizika; 1976; 21(4):629-33. PubMed ID: 1009144.
    Abstract:
    The relaxation curves in HbCO solutions to steady 1 and equilibrium 2 states were investigated at different temperatures and photolytic illumination intensities I. It was observed that in case of low I they were of identical shape and had more than one relaxation time. Increase of I leads to changes in the "tails" of curves 1 and in the initial parts of curves 2; the shape of curves 2 becomes simpler. The latter is interpreted as a result of a slow relaxation of the Hb molecules conformation to an equilibrium ligand-free state just after HbCO photodissociation.
