Effect of various solvents, cations, inhibitors, reducing agents, metal chelators, and denaturing agents on the activity of PepX and PepN from <i>Lb. helveticus</i> ATCC 12046 (at 37°C in 50 mM Na<sub>2</sub>HPO<sub>4</sub>/KH<sub>2</sub>PO<sub>4</sub> buffer, pH 6.5).
1<p>The value of 100% was determined in the presence of the corresponding solvent without the additional substance. The substance was dissolved in: <sup>2</sup>H<sub>2</sub>O<sub>dd</sub>; <sup>3</sup>DMSO; <sup>4</sup>Acetone; <sup>5</sup>EtOH. Triplicate measurements; the standard deviation was <5%; n.d., not determined.</p
