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−1s−1 vs. 0.14 M−1s−1....
