Abstract:
New chemical agents that could combat increasing antibiotic resistance are urgently needed. In this mini-review, an old but highly relevant RNA sequence which is crucial for the continuation of bacterial life-cycle is covered. Some of the most significant advances of the last decade in sensing and targeting the bacterial rRNA A-site: a well-validated binding site of proverbially known aminoglycoside antibiotics are described. Some of the major advances in direct sensing of the bacterial decoding side (A-site) are described and also new fluorescent molecules that are capable of detecting lead compounds through high-throughput assays by displacement of fluorescent probe molecules are highlighted. Lastly, some of the recently discovered non-aminoglycoside small molecule binders of bacterial rRNA A-site as a new class of molecules that could provide future scaffolds and molecules for developing new antibacterial agents have been discussed.

Types of RNA
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.

Bacterial RNA Polymerase
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...
