Belongs to the bacterial ribosomal protein bS21 family.
Belongs to the universal ribosomal protein uS10 family.
Involved in the binding of tRNA to the ribosomes.
Belongs to the bacterial ribosomal protein bL36 family.
Belongs to the bacterial ribosomal protein bL33 family.
A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability. Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems. Usually binds in the 5'-UTR; binding at or near the Shine-Dalgarno sequence prevents ribosome-binding, repressing translation, binding elsewhere in the 5'-UTR can activate translation and/or stabilize the mRNA. Its function is antagonized by small RNA(s).
Homodimer; the beta-strands of each monomer intercalate to form a hydrophobic core, while the alpha-helices form wings that extend away from the core.
