Kinetic rate constant for electron transfer between ferrous ions and novel rusticyanin isoform in Acidithiobacillus ferrooxidans
Here we report the kinetic rate constant for electron transfer from ferrous ions to a novel rusticyanin isoform in Acidithiobacillus ferrooxidans. The second order rate constant for this isoform is shown to be approximately one half that of the previously known type, 0.09 M(-1)s(-1) vs. 0.14 M(-1)s(-1).
