RiboLife is a collection of sequence alignments for ribosomal rRNA. Currently there are two versions each for the LSU and SSU.
Version 1.0 of the LSU RiboZones alignment has been released in PNAS (2014).

Version 1.0 of the SSU RiboZones alignment has been released in (publication pending, 2015).You can download it here.
Version 2.0 of these RiboZones alignments are (publication pending, 2018).
The alignment contains 133 sequences with broad phylogenetic representation from each domain of life (Bacteria, Archaea, Eukarya). The 23-28S rRNA sequences in RiboZones are full-length, aligned according to secondary and tertiary structure, and contain a single entry per species.
