Mg2+
Mn2+
-
can substitute for Mg2+ in either the forward or the reverse direction, 53% of the activation with Mg2+, excess of Mn2+ inhibits the reaction in both directions
maximum activity in the presence of Mg2+. 20 mM used in assay conditions
Mg2+
-
best fulfills the requirement for a divalent cation, maximal activity of forward reaction at a Mg2+/UTP ratio of 2:1. In the reverse reaction below 5 mM diphosphate, a Mg2+:diphosphate ratio of approximately 1:1 gives optimal activity, excess of Mg2+ is inhibitory
