Type A and B RNase P RNAs are interchangeable in vivo despite substantial biophysical differences.
We show that structural type A and B bacterial ribonuclease P (RNase P) RNAs can fully replace each other in vivo despite the many reported differences in their biogenesis, biochemical/biophysical properties and enzyme function in vitro. Our findings suggest that many of the reported idiosyncrasies of type A and B enzymes either do not reflect the in vivo situation or are not crucial for RNase ...
متن کاملRNase P RNAs from some Archaea are catalytically active.
The RNA subunits of RNase Ps of Archaea and eukaryotes have been thought to depend fundamentally on protein for activity, unlike those of Bacteria that are capable of efficient catalysis in the absence of protein. Although the eukaryotic RNase P RNAs are quite different than those of Bacteria in both sequence and structure, the archaeal RNAs generally contain the sequences and structures of the...
متن کاملEvolutionary variation in bacterial RNase P RNAs.
Sequences encoding RNase P RNAs from representatives of the last remaining classical phyla of Bacteria have been determined, completing a general phylogenetic survey of RNase P RNA sequence and structure. This broad sampling of RNase P RNAs allows some refinement of the secondary structure, and reveals patterns in the evolutionary variation of sequences and secondary structures. Although the se...

Thermostable RNase P RNAs lacking P18 identified in the Aquificales.
The RNase P RNA (rnpB) and protein (rnpA) genes were identified in the two Aquificales Sulfurihydrogenibium azorense and Persephonella marina. In contrast, neither of the two genes has been found in the sequenced genome of their close relative, Aquifex aeolicus. As in most bacteria, the rnpA genes of S. azorense and P. marina are preceded by the rpmH gene coding for ribosomal protein L34. This ...
