Mg2+
additional information
high salt concentration approximately 2.4 M is necessary for maximum activity
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+
