Detailed ATP‐stimulated kinetics of the Archaeoglobus fulgidus helicases (AfXPB). Normalized square wave voltammetry (SWV) peak current versus time after ATP addition for electrochemically active DNA monolayers treated with various concentrations of AfXPB helicase. (a) 8 nM AfXPB. (b) 20 nM AfXPB. (c) 40 nM AfXPB. (d) 20 nM AfXPB, longer timescale. Symbols indicate the data, solid curves are first‐order exponential decay fits to the data, and decay times are presented as average ± standard error of the mean for at least three trials.
