The RNA moiety of ribonuclease P is the catalytic subunit of the enzyme
TLDR
The RNA moieties of ribonuclease P purified from both E. coli and B. subtilis can cleave tRNA precursor molecules in buffers containing either 60 mM Mg2+ or 10 mM MG2+ plus 1 mM spermidine, and in vitro, the RNA and protein subunits from one species can complement sub units from the other species in reconstitution experiments.About:

The Structural Basis of Ribosome Activity in Peptide Bond Synthesis
TL;DR: It is established that the ribosome is a ribozyme and the catalytic properties of its all-RNA active site are addressed and the mechanism of peptide bond synthesis appears to resemble the reverse of the acylation step in serine proteases.

The noncoding RNA revolution-trashing old rules to forge new ones.
TL;DR: The pathway of ncRNA research is described, where every established "rule" seems destined to be overturned.

A General Purpose RNA-Cleaving DNA Enzyme
TL;DR: An in vitro selection procedure was used to develop a DNA enzyme that can be made to cleave almost any targeted RNA substrate under simulated physiological conditions, and its activity is dependent on the presence of Mg2+ ion.

Cleavage of Structural Proteins during the Assembly of the Head of Bacteriophage T4
TL;DR: Using an improved method of gel electrophoresis, many hitherto unknown proteins have been found in bacteriophage T4 and some of these have been identified with specific gene products.

Cleavage of structural proteins during the assemble of the head of bacterio-phage T4
TL;DR: Using an improved method of gel electrophoresis, many hitherto unknown proteins have been found in bacteriophage T4 and some of these have been identified with specific gene products as mentioned in this paper.

A simplified ultrasensitive silver stain for detecting proteins in polyacrylamide gels
TL;DR: The number of steps in the procedure is reduced from 10 to 6, the reagents in each step are simplified, and the amount of silver required is reduced by a factor of 10, thus greatly reducing the expense of the procedure.

Self-splicing RNA: Autoexcision and autocyclization of the ribosomal RNA intervening sequence of tetrahymena
Kelly Kruger,Paula J. Grabowski,Arthur J. Zaug,Julie Sands,Daniel E. Gottschling,Thomas R. Cech +5 more
TL;DR: It is proposed that the IVS portion of the RNA has several enzyme-like properties that enable it to break and reform phosphodiester bonds and that enzymes, small nuclear RNAs and folding of the pre-rRNA into an RNP are unnecessary for these reactions.

Elution of proteins from sodium dodecyl sulfate-polyacrylamide gels, removal of sodium dodecyl sulfate, and renaturation of enzymatic activity: Results with sigma subunit of Escherichia coli RNA polymerase, wheat germ DNA topoisomerase, and other enzymes
TL;DR: It is shown how the method can be used to determine the approximate molecular weight of the DNA topoisomerase polypeptide by sectioning a gel on which a partially pure sample has been fractionated by electrophoresis.
