Relative activity of SmPCS_66–591 and SmPCS_66–300 with different metals.

<p>Values are given as the percentage of activity (PC₂ synthesized µmol min⁻¹ mg⁻¹ enzyme) of respective enzyme in the absence of added metal in the presence of DTPA (6.3 mM). Mean value of three separate assays (± SE) are given (N = 3). The incubation mixtures contained 200 mM Tris-HCl (pH 8), 10 mM β-Me, 10 mM GSH, 3 µg of enzyme and the metal ion.</p>*<p>, p<0.05 by Student's t test.
