Activity of WT-sCoaT. (A) Co2+ stimulates the highest ATP hydrolysis activity. Results are the average of at least three independent replicates. Maximal activity for 100 μM Co2+ is 0.57 μmoles ATP mg−1 min−1. (B) Co2+ stimulated ATPase activity of WT-sCoaT. Fits were performed using Kaleidagraph software with the equation y = (Vmax*x)/(KM+x).
