The net result is a highly refined secondary and tertiary covariation-based structure model for 16S and 23S rRNA.
The first major category, Comparative Structure Models http://www.rna.icmb.utexas.edu/CSI/2STR/contains our most recent 16S and 23S rRNA covariation-based structure models, which were adapted from the original Noller & Woese models (16S [ 15 22 ] and 23S [ 19 ] rRNA), and the structure models for 5S rRNA [ 12 ] , tRNA [ 5 6 7 8 9 ] , and the group I [ 32 ] and group II [ 34 ] introns, as determined by others.
Base pair frequencies are presented for a) all base pairs in the current covariation-based structure models, b) tentative base pairs predicted with covariation analysis, and c) base pairs previously proposed with comparative analysis that are not included in our current structure models due to a lack of comparative support from the analysis with our best covariation methods on our current alignments (named "Lousy" base pairs).
Recently, we utilized this system to identify and quantitate the following biases for adenosines in the Bacterial 16S and 23S rRNA covariation-based structure models [ 63 ] : 1) approximately 2/3 of the adenosines are unpaired; 2) more than 50% of the 3' ends of loops in the 16S and 23S rRNA have an A; 3) there is a bias for adenosines to be adjacent to other adenosines (66% of these are at two unpaired positions, and 15% of these are at paired/unpaired junctions); and 4) the majority of the As at the 3' end of loops are adjacent to a paired G. These results were discerned with this system and are shown in part in Figure 5and H-4C.
The third, named "bpseq," is a simple text format that contains the sequence, one nucleotide per line, its position number, and the position number of the pairing partner (or 0 if that nucleotide is unpaired in the covariation-based structure model).
