Comparison of the effect of selected metal ions on the activities of NitraS-ATII and R. sphaeriodesLHS-305 nitrilase. Each panel shows the activity percentage in the presence of increasing concentrations of a metal ion. a. In presence of Ni2+, R. sphaeriodes LHS-305 nitrilase retains higher activity (t test p-value = 2.2x10-3). b. In presence of Zn2+, NitraS-ATII retains higher activity (t test p-value = 9.6x10-3). c. In presence of Mn2+, NitraS-ATII retains higher activity (t test p-value = 11.8x10-3)
