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).

16S rRNA

23S rRNA

Base Composition (excludes gaps):

Shannon Entropy:

* = zero variance (cannot be shown on log scale)

Domain Consensus

Clade Consensus

Consensus (R/Y/N): at each alignment position, if ≥70% of non-gap bases are A/G → R (purine) or ≥70% are C/U → Y (pyrimidine); otherwise → N. (Gaps are ignored.)
