The conserved U.G pair in the 5' splice site duplex of a group I intron is required in the first but not the second step of self-splicing.
Group I self-splicing introns have a 5' splice site duplex (P1) that contains a single conserved base pair (U.G). The U is the last nucleotide of the 5' exon, and the G is part of the internal guide sequence within the intron. Using site-specific mutagenesis and analysis of the rate and ac...
