PROSITE documentation PDOC00560

Ribosomal protein L9 signature

Description:

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 which, on the basis of sequence similarities [1,2], groups:

  • Eubacterial L9.
  • Cyanobacterial L9.
  • Plant chloroplast L9 (nuclear-encoded).
  • Red algal chloroplast L9.

As a signature pattern, we have selected a conserved region, located in the N-terminal section of these proteins.
