Summary
This chapter details in vivo methods to study small RNA (sRNA) and messenger RNA (mRNA) interactions in Bacillus subtilis. These techniques help elucidate regulatory sRNA mechanisms and interactions within the cell.
Area of Science:
- Microbiology
- Molecular Biology
- Genetics
Background:
- Small RNAs (sRNAs) are crucial regulators of gene expression in bacteria.
- Understanding sRNA-mRNA interactions is key to deciphering bacterial regulatory networks.
- Bacillus subtilis serves as a model organism for studying these interactions.
Purpose of the Study:
- To describe established and improved in vivo methods for analyzing sRNA-mRNA interactions in Bacillus subtilis.
- To provide a comprehensive guide for characterizing regulatory sRNA systems.
- To facilitate the investigation of RNA-RNA interactions within a cellular context.
Main Methods:
- Utilizing compatible plasmids or chromosomal modifications for in vivo studies.
- Employing transcriptional and translational reporter gene fusions to elucidate regulatory sRNA mechanisms.
- Determining expression profiles, half-lives, and intracellular concentrations of sRNA and mRNA.
- Investigating the role of RNA chaperones in promoting sRNA-mRNA interactions.
Main Results:
- Established and refined a suite of in vivo methods for sRNA-mRNA interaction analysis in B. subtilis.
- Successfully applied these methods to characterize multiple sRNA/target mRNA systems.
- Provided a framework for in-depth analysis through the combination of in vivo and in vitro approaches.
Conclusions:
- In vivo methods are essential for a comprehensive understanding of sRNA-mRNA interactions in Bacillus subtilis.
- The described techniques enable detailed characterization of regulatory sRNA function.
- Combining in vivo and in vitro approaches offers the most robust analysis of these molecular interactions.

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

5.1K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

3.5K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

29.5K
Unlike eukaryotes, bacteria use a single RNA Polymerase (RNAP) to transcribe all genes. The different subunits of bacterial RNAPhave distinct functions. The multisubunit structure of the bacterial RNAP helps the enzyme to maintain catalytic function, facilitate assembly, interact with DNA and RNA, and self-regulate its activity.
In most genes, the transcription site is a single base present upstream of the coding sequence. Though RNAP is a catalytically efficient enzyme, it does not recognize...

01:56Riboswitches
8.1K
Riboswitches are non-coding mRNA domains that regulate the transcription and translation of downstream genes without the help of proteins. Riboswitches bind directly to a metabolite and can form unique stem-loop or hairpin structures in response to the amount of the metabolite present. They have two distinct regions – a metabolite-binding aptamer and an expression platform.
The aptamer has high specificity for a particular metabolite which allows riboswitches to specifically regulate...
