Mg2+
maximum activity at 10 mM Mg2+

2.4.2.48
Mg2+
Mg2+ may be responsible for conformational rigidity of the tRNA, but not for the enzymatic activity itself. Mg2+ ion is required for activity with the T7 transcript as a substrate. Activity with unfractionated Escherichia coli tRNA does not require Mg2+
