Table 3 Effect of divalent cations on pepG1 activity
From: Identification and characterization of a bacterial glutamic peptidase
pepG1 was incubated for 30 min with the below cations at pH 4.0. The remaining activity was assayed at 37°C, pH 4.0 | ||
|---|---|---|
Cation | Concentration (mM) | Relative activity |
Cu2+ | 5 | 1.4 |
Fe2+ | 5 | 1.0 |
Zn2+ | 5 | 1.1 |
Mg2+ | 5 | 1.0 |
Mn2+ | 5 | 1.0 |
Ca2+ | 5 | 1.0 |
