PROSITE documentation PDOC00922

Ribosomal protein L1 signature





Description

Ribosomal protein L1 is the largest protein from the large ribosomal subunit. In Escherichia coli, L1 is known to bind to the 23S rRNA. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities [1,2], groups:

  • Eubacterial L1.
  • Algal and plant chloroplast L1.
  • Cyanelle L1.
  • Archaebacterial L1.
  • Vertebrate L10A.
  • Yeast SSM1.

As a signature pattern, we selected the best conserved region located in the central section of these proteins. It is located at the end of an α helix thought to be involved in RNA-binding.
