Table 1. Hill coefficients for the Ca2+ dependence of CaMKII autophosphorylation at varying concentrations of CaMKII and PP1.

[CaMKII], μM
[PP1], μM 0.2 1 5
0 4.4 ± 0.6 4.9 ± 0.3 5.4 ± 0.4
0.5 7.7 ± 0.8 6.6 ± 1.7 8.9 ± 1.8
1.25 6.5 ± 0.5 8.6 ± 2.5 6.9 ± 1.6
2.5 5.9 ± 0.3 8.9 ± 2.2

Each nH value represents the mean obtained from at least two Ca2+ titrations. nH values were often obtained at several time points, and these values were averaged to obtain the final value. Uncertainties are the SD.
