title: Identification and characterization of bacterial class E group II introns.
abstract: Group II introns are catalytic RNAs and mobile genetic elements. Phylogenetic characterization of group II intron-encoded reverse transcriptases (RTs) established seven classes: the mitochondrial class, chloroplast-like classes 1 and 2, and bacterial classes A, B, C, and D. In this study, we identified and characterized a new bacterial class of group II introns, bacterial class E, on the basis of phylogenetic analysis of the intron-encoded protein (IEP) RT and determination of a consensus intron RNA structure.
