Short name: Ribosomal_L21

Family relationships

Description

Ribosomal protein L21 is one of the proteins from the large ribosomal subunit. In Escherichia coli, L21 is known to bind to the 23S rRNA in the presence of L20. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities, groups:

  • Bacterial L21.
  • Marchantia polymorpha chloroplast L21.
  • Cyanelle L21.
  • Plant chloroplast L21 (nuclear-encoded).

Bacterial L21 is a protein of about 100 amino-acid residues, the mature form of the spinach chloroplast L21 has 200 residues.
