a Peptidyl transferase is the primary enzymatic functional part of the ribosome, which forms peptide links between adjacent amino acids using tRNAs during the translation process of protein biosynthesis.
In Bacteria, the 50S (23S component) ribosome subunit contains the peptidyl transferase component and acts as a ribozyme.

In eukaryotic cells, the 60S (28S component) ribosome subunit contains the peptidyl transferase component and acts as the ribozyme.
