A comparative database of group I intron structures.

We have created a database of comparatively derived group I intron secondary structure diagrams. This collection currently contains a broad sampling of phylogenetically and structurally similar and diverse structures from over 200 publicly available intron sequences. As more group I introns are sequenced and added to the database, we anticipate minor refinements in these secondary structure diagrams. These diagrams are directly accessible by computer as well as from the authors.
