Fig. 4From: A comparison of the enzymatic properties of three recombinant isoforms of thrombolytic and antibacterial protein—Destabilase-Lysozyme from medicinal leechIsopeptidase activity of mlDL-Ds3. The effect of pH (a) and ionic strength (b) on the isopeptidase activity of mlDL-Ds3. The effect of ionic strength on the isopeptidase activity was determined at pH 5.5. Isopeptidase activity was calculated according to formula (2). (n = 5)Back to article page
