Ribosomal protein L9 is one of the proteins from the large ribosomal subunit.
In Escherichia coli, L9 is known to bind directly to the 23S rRNA. It belongs
to a family of ribosomal proteins grouped on the basis of sequence similarities [, 8306963].
The crystal structure of Bacillus stearothermophilus L9 shows the 149-residue protein comprises two globular domains connected by a rigid linker . Each domain contains an rRNA binding site, and the protein functions as a
structural protein in the large subunit of the ribosome. The C-terminal domain consists of two loops, an alpha-helix and a three-stranded mixed
parallel, anti-parallel beta-sheet packed against the central alpha-helix. The long central alpha-helix is exposed to solvent in the middle and participates in the
hydrophobic cores of the two domains at both ends.
