  1. This table was constructed from [2]. The values listed were taken from searches of the Pfam website. Ribosomal proteins L20A and L30E were not well defined in Pfam so BLAST searches were performed instead. These results support the eocyte hypothesis, but it is plausible that there were independent losses of ribosomal subunits in archaea based on additional data.
