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.
