PROSITE documentation PDOC00778Ribosomal protein L19 signature
Description
Ribosomal protein L19 is one of the proteins from the large ribosomal subunit. In Escherichia coli, L19 is known to be located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities, groups:
- Eubacterial L19.
- Red algal chloroplast L19.
- Cyanelle L19.
L19 is a protein of 120 to 130 amino-acid residues. As a signature pattern, we selected a conserved region in the C-terminal section.
