We investigated the self-splicing properties of two introns from the bacterium Bacillus anthracis. One intron (B.a.I1) splices poorly in vitro despite having typical structural motifs, while the second (B.a.I2) splices well while having apparently degenerated features. The spliced exons of B.a.I2 were sequenced, and splicing was found to occur at ... More
