Webb14 mars 2024 · As to the mechanism by which G1 inhibits fMet-tRNA binding, the finding that non-coded, IF2-GTP-assisted, binding of fMet-tRNA to the 30S subunit is not affected by the antibiotic suggests that codon–anticodon pairing in the P-site plays a central role as a target of the inhibition; this premise is further underlined by the surprising finding that … WebbTo our knowledge this study provides the first direct evidence that a 30S subunit bound to the 5′ end of a mRNA protects it from endonucleolytic cleavage by RNase E. Indirect evidence for this has been provided by Wagner et al. (1994)and Arnold et al. (1998), who showed that mRNA stability depends on efficient ribosome loading at the RBS. making sheepskin condoms

Bacterial 30S Ribosomal Subunit - an overview

Webb-Reversibly bind 30S ribosomal subunit. -Blocks attachment of tRNA to ribosome. -Prevents continuation of protein synthesis. -Effective against certain Gram + and Gram - . -Newer tetracyclines such as doxycycline have longer half-life (allows for less frequent dosing). -Resistance due to decreased accumulation by bacterial cells. WebbAnother class of antibacterial compounds that bind to the 30S subunit is the tetracyclines. In contrast to aminoglycosides, these drugs are bacteriostatic and inhibit protein synthesis by blocking the association of tRNAs with the ribosome during translation.
