Translational Control of Ribosomal Protein Synthesis

Other operons carrying ribosomal protein genes are regulated in a similar manner. Most ribosomal protein genes exist in operons with promoters at one end. In some cases, individual operons are regulated by one of the encoded ribo- 

Schematic diagram explaining autogenous inhibition by LI. LI can form a complex either with the 5 end of its own mRNA or with 23S rRNA. If there is an excess of LI over the available 23S rRNA, then LI binds to the 5 end of the mRNA and inhibits both LI and Lll synthesis. The inhibition of LI translation by this binding depends on the fact that the translation of LI and Lll is somehow coupled.
