Cbu.L1917, a group I intron present in the 23S rRNA gene of Coxiella burnetii, possesses a unique 3'-terminal adenine in place of a conserved guanine. Here, we show that, unlike all other group I introns, Cbu.L1917 utilizes a different cofactor for each splicing step and has a decreased self-splicing rate in vitro.
