The environment of two metal ions surrounding the splice site of a group I intron.
Several divalent metal ions (Ca2+, Sr2+ and Pb2+) do not promote splicing, but instead induce cleavage at a single site in the conserved group I intron core in the absence of the guanosine cofactor at elevated pH, generating products with 5'-OH and 3'-phosphate ends. The reaction is compet...
