Ribosomal protein L27 signature


Ribosomal protein L27 is one of the proteins from the large ribosomal subunit. L27 belongs to a family of ribosomal proteins which, on the basis of sequence similarities [1,2], groups:

  • Eubacterial L27.
  • Plant chloroplast L27 (nuclear-encoded).
  • Algal chloroplast L27.
  • Yeast mitochondrial YmL2 (gene MRPL2 or MRP7).

The schematic relationship between these groups of proteins is shown below.

't': transit peptide.
'N': N-terminal of mature protein.
