ORF-less Group II Introns

Clicking on the intron abbreviation in the "Name" column brings up full entries for individual introns that include intron and flanking sequence, ORF sequence, and intron RNA secondary structure. The table can be sorted by any of the column headings simply by clicking on the link at the top. In addition, the accession numbers are linked to the individual GenBank entries.
Note on nomenclature: Introns are named according to a species abbreviation and intron number. In cases where introns of the same (or almost identical) sequence have inserted in multiple genomic sites, or are reported in multiple GenBank entries, only one example is shown in the table. Hence the table is intended to be a listing of full-length, functional and unique introns in GenBank.
Note on host gene annotation: Host genes (i.e. exons) are assigned by a combination of manual and automatic processes, and so the assignments should be treated with caution.
