Effect of divalent cations on purified D10 plasma membranes ATPase activity.
| Cations | ATPase activity (% of control) |
| Mg2+ (control) | 100 |
| Mn2+ | 87.8 ± 33.1 |
| Ca2+ | 20.9 ± 19.2 |
ATPase activity was determined using 2 mM concentration of Mg2+, Mn2+ and Ca2+ and the ATPase activity in the absence of divalent cation was subtracted. Values are means of three separate experiments, each performed in quadruplicate ± standard deviations and are expressed as % of control in presence of Mg2+.
