Mycobacterium tuberculosis 6C sRNA binds multiple mRNA targets via C-rich loops independent of RNA chaperones

Nucleic Acids Research, 2019
Bacterial small regulatory RNAs (sRNAs) are the most abundant class of post-transcriptional regulators and have been well studied in Gram-negative bacteria.

Balancing gene expression without library construction via a reusable sRNA pool

Nucleic Acids Research, 2017
Balancing protein expression is critical when optimizing genetic systems. Typically, this requires library construction to vary the genetic parts controlling each gene, which can be expensive and time-consuming.

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 ...

sRNA-dependent control of curli biosynthesis in Escherichia coli: McaS directs endonucleolytic cleavage of csgD mRNA

Nucleic Acids Research, 2018
Production of curli, extracellular protein structures important for Escherichia coli biofilm formation, is governed by a highly complex regulatory mechanism that integrates multiple environmental signals through the involvement of numerous proteins and ...

Stepwise sRNA targeting of structured bacterial mRNAs leads to abortive annealing.

Molecules and Cells, 2020
Bacterial small RNAs (sRNAs) regulate the expression of hundreds of transcripts via base pairing mediated by the Hfq chaperone protein. sRNAs and the mRNA sites they target are heterogeneous in sequence, length, and secondary structure. To understand how

Ultrasound workshop: by the SRNA for the SRNA

2019
Although only adopted recently, the use of ultrasound in anesthesia practice has been defined through its reduction in complications, increased effectiveness of regional anesthesia, and enhanced quality of central venous catheter placement. As noted by the Council on Accreditation (COA), Student Registered Nurse Anesthetists (SRNA’s) should have ...

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.
