Comparative sequence analyses of the ribonuclease P (RNase P) RNA genes from LL-2,6-diaminopimelic acid-containing actinomycetes.
Ribonuclease P (RNase P) RNA genes of LL-2,6-diaminopimelic acid (LL-A2pm)-containing actinomycetes, except Streptomyces species, were sequenced after PCR-amplification and cloning. By using the sequence data, the relationships between species within genera and the relationships between taxa above genus level were investigated and the usefulness of the RNase P RNA gene as another phylogenetic m...
متن کاملApplication of the ribonuclease P (RNase P) RNA gene sequence for phylogenetic analysis of the genus Saccharomonospora.
Sequences of the RNase P RNA gene were investigated for the phylogenetic analysis of the genus Saccharomonospora. Aligned nucleotide sequences, determined from the PCR-amplified RNase P RNA gene of representative strains of the genus Saccharomonospora, displayed 94.2 +/- 1.3% interspecific variances. The intraspecific similarity value was 99.7-100% in all species tested. Saccharomonospora azure...
متن کاملComparative analysis of ribonuclease P RNA of the planctomycetes.
The planctomycetes, order Planctomycetales, are a distinct phylum of domain Bacteria. Genes encoding the RNA portion of ribonuclease P (RNase P) of some planctomycete members were sequenced and compared with existing database planctomycete sequences. rnpB gene sequences encoding RNase P RNA were generated by a conserved primer PCR strategy for Planctomyces brasiliensis, Planctomyces limnophilus...
متن کاملComparative analysis of ribonuclease P RNA structure in Archaea.
Although the structure of the catalytic RNA component of ribonuclease P has been well characterized in Bacteria, it has been little studied in other organisms, such as the Archaea. We have determined the sequences encoding RNase P RNA in eight euryarchaeal species: Halococcus morrhuae, Natronobacterium gregoryi, Halobacterium cutirubrum, Halobacteriurn trapanicum, Methanobacterium thermoautotro...
متن کاملNew insight into RNase P RNA structure from comparative analysis of the archaeal RNA.
A detailed comparative analysis of archaeal RNase P RNA structure and a comparison of the resulting structural information with that of the bacterial RNA reveals that the archaeal RNase P RNAs are strikingly similar to those of Bacteria. The differences between the secondary structure models of archaeal and bacterial RNase P RNA have largely disappeared, and even variation in the sequence and s...
