About This Section:
The introns that occur in 16S and 23S rRNAs are organized into four preconfigured tables that disseminate the intron information and emphasize the major dimensions inherent in this data:
- intron position in the rRNA,
- intron type,
- number of introns per exon gene, and
- phylogenetic distribution.
The information collected on this rRNA Introns page is the basis for two detailed analyses that have been published elsewhere:
- the spatial distribution of introns on the three-dimensional structure of the 16S and 23S rRNA (Jackson et al., 2002); and
- the statistical analysis of the distribution of spliceosomal introns on the rRNA (Bhattacharya et al., 2003).
rRNA Introns Data:
| Table | Description |
|---|---|
| 1: Primarily Sorted by Intron Position | |
| A: Mean Frequency of Introns in rRNA Positions | 16S/23S |
| B: Number of Intron Types per Intron Position | |
| C: Number of Introns Identified for each Intron Position | |
| D: Number of Introns for each Intron Position | 16S 23S 16S/23S |
| E: Secondary Structure Diagrams Showing Intron Positions for Escherichia coli (June 2002) | 16S: PS | PDF 23S 5': PS | PDF 23S 3': PS | PDF |
| 2: Primarily Sorted by Intron Type for each rRNA Gene | 16S 23S 16S/23S |
| 3: Primarily Sorted by Number of Introns Per rRNA Gene | 16S/23S |
| 4: Primarily Sorted by Phylogenetic Distribution of rRNA Introns | Archaea, Bacteria, Eukaryota |
