Ribosomal RNA and ribosomal proteins in corynebacteria
Journal of Biotechnology, 2003Ribosomal RNAs (rRNAs) (16S, 23S, 5S) encoded by the rrn operons and ribosomal proteins play a very important role in the formation of ribosomes and in the control of translation. Five copies of the rrn operon were reported by hybridization studies in Brevibacterium (Corynebacterium) lactofermentum but the genome sequence of Corynebacterium glutamicum ...

Publisher Summary This chapter reviews that the ribosomal cistrons of both bacteria and eukaryotes, with their unique and well-defined characteristics, have increasingly attracted the attention of biochemists and geneticists. It discusses that the arrangement of the ribosomal cistrons on the chromosomal DNA, and they have been mapped in some detail ...

1. The G + C content of ribosomal RNA of animals seems correlated with the length of periods required for maturation of those organisms. 2. In Protostomes of the animal kingdom, the size of the 28S rRNA molecule does not seem to correlate with the evolutionary stage of the organism. 3.

Ribosomal RNA on the Surface of Ribosomes
Science, 1963Ribonuclease from pancreas releases nucleotide from Escherichia coli ribosomes while not altering significantly the base composition of the total ribosomal RNA. Ribonuclease hydrolyzes ribsomal RNA without destroying the structure of 70 S or 30 S and 50 S

Small Nucleolar RNAs Guide Ribosomal RNA Methylation
Science, 1996Two recent reports, one in Cell and one in the Journal of Molecular Biology , show that the newly described small nucleolar RNAs control the site of methylation of the ribosomal RNA (rRNA). Tollervey explains how these small RNAs accomplish this targeting and discusses the possible role of ...

For a long time, cytochrome c, which is a slowly evolving protein, was the reference molecule to establish molecular phylogenies for very divergent eukaryotic lineages (Fitch and Margoliash 1967). Considering bacterial and chloroplastic c-type cytochomes together with cytochrome c, the first universal phylogenetic tree has been established. However, in
