Effects of helicase mutations on ATP hydrolysis. (A) PhosphorImages of representative TLC plates show hydrolysis of α-32P-ATP incubated with Dcr-2WT, Dcr-2F225G, or Dcr-2G31R, with BLT (left) or 3′ovr (right) 52-dsRNA, o, origin. (B) Quantification of data from panel A (mean ± SD, n = 3) fit with the pseudo first-order equation as in 4B.
