NAG₂ inhibition of HCHT.

<p>(A) Activity of HCHT on MU-NAG₂ substrate as a function of substrate concentration. (B) NAG₂ inhibition of HCHT on MU-NAG₂ substrate measured at 3 different substrate concentrations—0.5 μM, 5 μM or 50 μM. (C) NAG₂ inhibition of HCHT on ¹⁴C-CNW substrate (1.0 g/L). <i>v</i>_i and <i>v</i>_{i = 0} stand for the rates measured in the presence and absence of inhibitor, respectively. Error bars show standard deviations and are from three independent experiments.
