    • For the in vitro enzyme activity assay, the active cysteine proteases were dissolved in AHNP buffer (150 mM acetate/2-[4-(2-hydroxyethyl)-1- piperazinyl]ethanesulfonic acid (HEPES) pH 6.5, 300 mM NaCl; 0.001, pluronic, 5-100 mM cysteine depending on the enzyme) at a final concentration of 10 nM. The substrates 2, 4, and 5, dissolved in DMSO, were added at concentrations of 98 μM (2) and 24 μM (4 and 5, and fluorescence was measured with a Tecan SAFIRE II spectrometer. The final DMSO concentration in the assay did not exceed 1, v/v, Steady-state kinetics were fitted by nonlinear least-squares regression using v, A]V/(K M+1, A]/Ksi, A, where v is the initial velocity, V is the maximal rate, KM is the Michaelis-Menten constant, and Ksi is the constant for substrate inhibition
    • si is the constant for substrate inhibition.
