    3.5.4.12 | Ca2+ |
activation of enzyme by dCTP or inhibition by TTP has absolute requirement for the presence of a divalent cation. Mg2+, Ca2+ and Mn2+ are equally effective cations for enzyme activation by dCTP, Mn2+ and Ca2+ are more effective than Mg2+ in enzyme inhibition by TTP |

| 3.5.4.12 | Ca2+ |
can partially substitute for Mg2+ |
688732 |
| 3.5.4.12 | Ca2+ |
can partially substitute for Mg2+, 50% of the activity with Mg2+ |
688405 |
| 3.5.4.12 | Ca2+ |
divalent cations not necessary to improve activity, activation by dCTP and inhibition by dTTP both show an absolute requirement for a divalent cation. Mg2+, Ca2+ and Mn2+ almost equally effective in promoting activation by dCTP, Cu2+, Zn2+, and Co2+ are ineffective |
289018 |
| 3.5.4.12 | Ca2+ |
no activation |
289005 |
| 3.5.4.12 | Ca2+ |
reaction completely dependent on divalent cations, most effective Mg2+, Mn2+ and Ca2+ less effective than Mg2+ |
289004 |
| 3.5.4.12 | Co2+ |
divalent cations not necessary to improve activity, activation by dCTP and inhibition by dTTP both show an absolute requirement for a divalent cation. Mg2+, Ca2+ and Mn2+ almost equally effective in promoting activation by dCTP, Cu2+, Zn2+, and Co2+ are ineffective |
289018 |
| 3.5.4.12 | Co2+ |
metal ion required, highest activity with Zn2+, about 20% activity with Co2+, Mn2+, and Ni2+ |
289005 |
| 3.5.4.12 | divalent cations |
divalent cations not necessary to improve activity, activation by dCTP and inhibition by dTTP both show an absolute requirement for a divalent cation. Mg2+, Ca2+ and Mn2+ almost equally effective in promoting activation by dCTP, Cu2+, Zn2+, and Co2+ are ineffective |
