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.

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.

Systemic silencing: Mobile sRNA stabilizes genomes

Nature Plants, 2016
Transcriptional gene silencing is a pivotal mechanism for regulating gene expression and genome stability. In Arabidopsis, combined analyses of small RNAs (sRNAs) and DNA methylation reveals that mobile 24-nt sRNAs are involved in reinforcing genome-wide silencing of transposons through DNA methylation.

Ethionine induced sRNA neomethylase activity

Biochemical and Biophysical Research Communications, 1968
Abstract Recent studies in this laboratory have been directed towards the methylation of sRNA using adult, embryonic, and neoplastic mouse liver cell preparations Hancock, 1966 , Hancock, 1967 , Hancock, 1967 , Hancock et al., 1967 . After characterizing the sRNA ethylase activity of mouse liver (manuscript submitted) investigations were ...

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 ...

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.

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.

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.
