Table 1 The effect of divalent metal ions on lytic activity of peptidase M15A enzyme

From: Cloning, expression, and characterization of a peptidoglycan hydrolase from the Burkholderia pseudomallei phage ST79

Relative lytic activity (%)a
Without metal ions (control) 100.0 ± 1.98
Metal ions 100 μM 1000 μM
Mg2+ 110.0 ± 2.6 50.3 ± 6.8
Ca2+ 106.1 ± 5.4 95.3 ± 4.2
Mn2+ 111.9 ± 0.4 65.6 ± 21.5
  1. aThe activities are shown as percentages in relation to the non-treated peptidase M15A control. Values represent the mean ± standard deviation of triplicate experiments
