Ribosomal protein S17 signature
Description
Ribosomal protein S17 is one of the proteins from the small ribosomal subunit. In Escherichia coli, S17 is known to bind specifically to the 5' end of 16S ribosomal RNA and is thought to be involved in the recognition of termination codons. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities [1,2,3], groups:
- Eubacterial S17.
- Plant chloroplast S17 (nuclear encoded).
- Red algal chloroplast S17.
- Cyanelle S17.
- Archaebacterial S17.
- Mammalian and plant cytoplasmic S11.
- Yeast S18a and S18b (RP41; YS12).
As a signature pattern, we selected the best conserved regions located in the C-terminal section of these proteins.
