Ribosomal protein L11 signature





Description

Ribosomal protein L11 is one of the proteins from the large ribosomal subunit. In Escherichia coli, L11 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 L11.
  • Plant chloroplast L11 (nuclear-encoded).
  • Read algal chloroplast L11.
  • Cyanelle L11.
  • Archaebacterial L11.
  • Mammalian L12.
  • Plants L12.
  • Yeast L12 (YL15).

L11 is a protein of 140 to 165 amino-acid residues. As a signature pattern, we have selected a conserved region located in the C-terminal section of these proteins. In Escherichia coli, the C-terminal half of L11 has been shown [3] to be in an extended and loosely folded conformation and is likely to be buried within the ribosomal structure.
