Inability of sRNA derived from peptidyl sRNA to accept amino acids

Biochemical and Biophysical Research Communications, 1967
Abstract sRNA isolated from polyphenylalanyl sRNA does not accept phenylalanine. The isolation procedure is mild enough to recover most of the usual sRNA. This observation suggests two possibilities: 1) sRNA becomes more labile when linked to polyphenylalanine or 2) sRNA in polyphenylalanyl sRNA is different from the usual sRNA which accepts amino ...

Species specificity of sRNA's and aminoacyl-sRNA synthetases in some aerobic bacteria

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1966
Abstract The compatability of the sRNA's and the aminoacyl-sRNA synthetases of two strains of Pseudomonas aeruginosa , and one each of Pseudomonas fluorescens , Achromobacter sp., and Saccharomyces cerevisiae was determined with a view to assessing the usefulness of this relationship as a taxonomic aid.

Sedimentation studies on aminoacyl-sRNA synthetase and activation of aminoacyl-sRNA transfer factor

Archives of Biochemistry and Biophysics, 1965
Abstract Sucrose density gradient centrifugation analysis of aminoacyl-sRNA transfer factor and aminoacyl-sRNA synthetase revealed that aminoacyl-sRNA transfer factor for various amino acids sedimented similarly, and the sedimentation coefficient was approximately 4 S.

Aminoacyl Position in Aminoacyl sRNA

Science, 1964
Chromatographic systems capable of resolving the 2′- and 3′-isomers of valyladenosine and N -acetylvalyladenosine are used to show that valyladenosine isolated from valyl-sRNA is the equilibrium mixture of 2′- and 3′-acyl isomers by the time of chromatography.

Specific binding of sRNA to ribosomes during polypeptide synthesis and the nature of peptidyl sRNA

Journal of Molecular Biology, 1967
Abstract Data are presented which suggest that one molecule of aminoacyl sRNA and one molecule of peptidyl sRNA are bound to a ribosome during polypeptide synthesis. Puromycin does not alter the amount of bound aminoacyl sRNA under the conditions which allow peptide bond formation whereas it reduces the amount of bound peptidyl sRNA.

Diverse Functions of Small RNAs (sRNAs) in Halophilic Archaea: From Non-coding Regulatory sRNAs to Microprotein-Encoding sRNAs

2017
The number of experimentally-verified small RNAs (sRNAs) in haloarchaea has increased tremendously since their discovery in 2009. A recent dRNA-Seq study led to the identification of about 2900 non-coding primary transcripts, a number that was much higher than the less than 1900 protein-coding mRNAs that were detected.

Detecting sRNAs by Northern Blotting

2011
Small RNAs (sRNAs) play fundamental roles in modifying the transcriptomes and proteomes of organisms. sRNAs can be classified according to their origin and way of action into classes such as microRNAs, trans-acting siRNAs, heterochromatin siRNAs, Piwi-interacting RNAs, and natural antisense siRNAs, although microRNAs are the most conserved and studied ...

Computational Identification of sRNA Targets

2012
Many small noncoding RNAs (sRNAs) in bacteria act as posttranscriptional regulators by base pairing to their message targets. TargetRNA is a program that predicts the targets of a sRNA by identifying messages with significant potential to base pair with the sRNA.

Formation of terminal uridylate sequences on sRNA

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1966
Abstract It has been shown that the terminal -pCpCpA sequence of sRNA can be removed and replaced enzymatically on a significant proportion of the molecules by -pU, -pUpA, -pUpC and -pCpU.

The synthesis of glycyl-l-phenylalanyl-sRNA

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1967
Abstract Glycyl- l -phenylalanyl-sRNA was prepared by acylation of l -phenylalanyl-sRNA. The method involves the use of N-hydroxysuccinimide ester of N-protected glycine as a highly specific reagent which acylates only the amino group of the phenylalanine bound to the sRNA and does not react with any of the functional groups of sRNA.
