Figure 5From: Cloning, expression and characterization of a pectate lyase from Paenibacillus sp. 0602 in recombinant Escherichia coliEffects of different Ca2+concentrations on the activity of the purified recombinant PelN. The assays were performed under pH 9.8 at 45°C with the addition of different concentrations of Ca2+. The activity under the standard conditions without any chemicals was used as a reference (100%). Error bars represent ± SD (n = 4).Back to article page
