Ribosome 30s subunit

Webb7 sep. 2024 · The ribosomal maturation factor (RimP) is a 17.7 kDa protein and is the assembly factor of the 30S subunit. RimP is essential for efficient processing of 16S rRNA and maturation (assembly) of the 30S ribosome. It was suggested that RimP takes part in stabilization of the central pseudoknot at the early stages of the 30S subunit maturation, … WebbRibosome assembly. Aminoglycosides prevent ribosome assembly by binding to the bacterial 30S ribosomal subunit. Aminoacyl tRNA entry. Tetracyclines and Tigecycline (a glycylcycline related to tetracyclines) block the A site on the ribosome, preventing the binding of aminoacyl tRNAs. Proofreading
