Mg2+ effects on a circle opening reaction of the self-splicing intervening sequence from Tetrahymena thermophila.
The Mg2+ contribution to the reaction of circular intervening sequence (CIVS) from rRNA precursor of Tetrahymena thermophila with a dinucleotide CU has been investigated. The results indicated that the circle opening of CIVS may involve binding of a weakly held Mg2+ ion.
