Ribosomal protein L22 signature





Description

Ribosomal protein L22 is one of the proteins from the large ribosomal subunit. In Escherichia coli, L22 is known to bind 23S rRNA. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities [1,2,3], groups:

  • Eubacterial L22.
  • Algal and plant chloroplast L22 (in legumes L22 is encoded in the nucleus instead of the chloroplast).
  • Cyanelle L22.
  • Archaebacterial L22.
  • Mammalian L17.
  • Plant L17.
  • Yeast YL17.

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

April 2006 / Pattern revised.
