Ancestral Vibrio 5S rRNA Sequence. The secondary structure is shown in an orientation that resembles that seen in the 50S subunit crystal structure. The seven highlighted bases indicate locations where the ancestral sequence (node 1) differs from the wild type V. proteolyticus sequence. Position numbering is the same for E. coli and V. proteolyticus.
