FIG. 5.

Inhibition of vEP by nPP. vEP-34 (100 nM) was incubated without or with different concentrations of nPP at 37°C for 10 min (•) or overnight (○), and the residual proteolytic activity was measured with prewarmed azocasein and with a final enzyme concentration of 80 nM. Data are means ± standard deviations from two experiments carried out in triplicate.
