Abstract:
The increase in antibiotic-resistant microorganisms has driven a search for new antibiotic targets and novel antimicrobial agents. A large number of different antibiotics target bacterial ribosomal subunit formation. Several specific ribonucleases are important in the processing of rRNA during subunit biogenesis. This work demonstrates that the ribonuclease inhibitor, vanadyl ribonucleoside complex (VRC), can inhibit RNases involved in ribosomal subunit formation. The ribosomal subunit synthesis rate was significantly decreased and ribosomal RNA from the subunit precursors was degraded. VRC had no inhibitory effect on translation. VRC also potentiated the inhibitory effects of an aminoglycoside and a macrolide antibiotic.

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.
