The 5S ribosomal RNAs ofParacoccus denltrificansandProchloron

Abstract
The nucleotide sequences of the 5S rRNAs of Paracoccus denitrificans and Prochloron sp. are respectively. Specific phylogenetic relationships of P. denitrificans with purple non-sulphur bacteria, and of Prochloron with cyanobacteria are demonstrated, and unique features of potential secondary structure are described.
