5S secondary structure domain (placeholder — reuses 16S domain boundaries) ⓘ
5S has no real domain/structure data yet — this reuses the 16S domain boundaries as a placeholder. Segments light up to show which region your selected 5S positions fall in.
16S secondary structure domain ⓘ
Segments light up to show which structural domain(s) your selected 16S positions fall in. Domain boundaries (E. coli numbering) follow the standard crystallographic assignment (5′ domain ~27–556, central domain ~564–912, 3′ major domain ~923–1391, 3′ minor domain ~1392–1542).
23S secondary structure domain ⓘ
Segments light up to show which structural domain(s) your selected 23S positions fall in. Domain boundaries (E. coli numbering) follow Petrov et al. 2013, Nucleic Acids Research, Table 2. Gray slivers are unassigned linker regions between domains.
Ribosome Atlas is an interactive resource for exploring ribosomal RNA diversity across microbial life. The site integrates large-scale phylogenies, multiple sequence alignments, and structural visualizations to enable comparative analysis of ribosomal variation across taxonomic levels. By linking evolutionary context with alignment and structure-derived features, Ribosome Atlas aims to support research in RNA evolution, function, and data-driven structure modeling. Data is based on GTDB release r220 (April 2024).
