Large subunit ribosomal ribonucleic acid (LSU rRNA) is the largest of the two major
RNA
Ribonucleic acid (RNA) is a polymeric molecule that is essential for most biological functions, either by performing the function itself (non-coding RNA) or by forming a template for the production of proteins (messenger RNA). RNA and deoxyrib ...
components of the
ribosome
Ribosomes () are molecular machine, macromolecular machines, found within all cell (biology), cells, that perform Translation (biology), biological protein synthesis (messenger RNA translation). Ribosomes link amino acids together in the order s ...
.
Associated with a number of
ribosomal proteins, the LSU rRNA forms the large subunit of the ribosome.
The LSU rRNA acts as a
ribozyme, catalyzing
peptide bond formation.
Characteristics
Use in phylogenetics
LSU rRNA sequences are widely used for working out
evolutionary relationships among organisms, since they are of ancient origin and are found in all known forms of life.
