Ribosomal protein L19 leader

L19 Ribosomal protein leaders are part of the ribosome biogenesis. They were used as an autoregulatory mechanism to control the concentration of ribosomal proteins L19. This family is a putative ribosomal protein leader autoregulatory structure[1] found in B. subtilis and other low-GC Gram-positive bacteria. It is located in the 5′ untranslated regions of mRNAs encoding ribosomal protein L19 (rplS). More examples were predicted in Flavobacteria[2] or Firmicutes[3] with bioinformatic approaches. The structures of all these predicted L19 ribosomal leaders are similar.
