Fitted parameters for ATP titration kinetics in human TRAP1 WT:D158N heterodimer mixture

The K0.5 here reports on the apparent affinity constant for ATP in the Michaelis-Menten equation. The unit for Vmax is expressed in μm ATP min−1m ATPase, and the unit for K0.5 is expressed in μm. The S.E. values from fitting are shown for each parameter.

MgCl2 CaCl2
Vmax 3.77 ± 0.06 2.31 ± 0.15
K0.5 ATPm) 72.5 ± 4.4 273.2 ± 39.2
