WebProtein Synthesis Inhibitors That Bind the 50S Subunit. There are several classes of antibacterial drugs that work through binding to the 50S subunit of bacterial ribosomes. Specific examples include erythromycin, azithromycin, and chloramphenicol. The first drug discovered in this category was erythromycin. WebDec 27, 2024 · The erythromycin cannot bind to the ribosome, and the bacteria can continue protein synthesis. [9] [10] Aside from being a bacteriostatic macrolide antibiotic, erythromycin is a pro-motility drug. It is an agonist to motilin, which increases motility in …
Erythromycin displays bacteriostatic activity or inhibits growth of bacteria, especially at higher concentrations. By binding to the 50s subunit of the bacterial rRNA complex, protein synthesis and subsequent structure and function processes critical for life or replication are inhibited. Erythromycin interferes with aminoacyl translocation, preventing the transfer of the tRNA bound at the A site of the rRNA complex to the P site of the rRNA complex. Without this translocation, the …
