A COMPARATIVE DATABASE OF GROUP INTRON STRUCTURES

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