Corrigendum to “Interaction between Gallotannin and a Recombinant Form of Arginine Kinase of Trypanosoma brucei: Thermodynamic and Spectrofluorimetric Evaluation”

In the article titled “Interaction between Gallotannin and a Recombinant Form of Arginine Kinase of Trypanosoma brucei: Thermodynamic and Spectrofluorimetric Evaluation” [1], there were a typo in Equation (7), where the denominator K2 should be corrected to K1, and an error in Table 2, where the values for Δ H, Δ S, and Δ G were incorrectly calculated. The equation and table are corrected as follows:

$$\begin{array}{c}\ln \frac{\mathrm{k}\mathrm{2}}{\mathrm{k}\mathrm{1}}=\left(\frac{1}{\mathrm{T}\mathrm{1}}–\frac{1}{\mathrm{T}\mathrm{2}}\right)\frac{\mathrm{\Delta }{\mathrm{H}}_{\mathrm{o}}}{\mathrm{R}}.\end{array}$$ (7)
