- Description
- A comparison among three models<sup>4−6</sup> for reassociation of CO with carp-hemoglobin, in R state, is made for temperatures below 200K. The experimental data utilized are from Cobau et al.<sup>7</sup> who analyzed them according to one of these models. The differences among the models lead to distinct shapes of their en ergy distributions. Nevertheless it was verified that the peak energy of these distributions and the Arrhenius frequency factor are independent of the models. Their values are smaller for hemoglobin than for myoglobin<sup>6</sup> and the distribution is wider for myoglobin, showing that it has a larger number of conformational substates. The three models studied reproduce well the experimental curves of 100K, 140K and 180K.
