Stoichiometric activity titrations of wild-type and mutant PSI-KH03

Enzyme	Eq. Pt.^a
^aAll measurements of the stoichiometric equivalence point are the average of two to four separate experiments, with errors reported as one standard deviation from the average.
Wild type	0.37 ± 0.03
I145N	0.71± 0.05
I234N	0.8 ± 0.2
I338N	0.8 ± 0.2
I449N	0.54 ± 0.05
