Divalent metal ion binding to a conserved wobble pair defining the upstream site of cleavage of group I self-splicing introns.
The upstream site of cleavage of all group I self-splicing introns is identified by an absolutely conserved U.G base pair. Although a wobble C.A pair can substitute the U.G pair, all other combinations of nucleotides at this position abolish splicing, suggesting that it is an unusual RNA structure,...
