The authors would like to apologize for an error in Figure legend 1c. The curves were mislabeled. The corrected Figure legend 1c is given below.
(c) Time-course study over 120 min pre-incubation of the ATPase activity of MSH2–MSH6 (160 nM) in the presence (open triangles) and the absence of Cd2+ (closed squares). The average of three experiments for each time point is presented. Standard deviation is included. Curves were fitted by linear regression analysis.
