The enzyme peptidyl transferase of prokaryotes resides in

50 S ribosome

30 S ribosome

40 S ribosome

60 S ribosome

50 S ribosome

The peptidyl transferase is an aminoacyl transferase as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the translation process of protein biosynthesis.

In prokaryotes, the 50 S (23 S component) ribosome subunit contains the peptidyl transferase component and acts as a ribozyme. In eukaryotes, the 60S (28S component) ribosome subunit contains the peptidyl transferase component and acts as the ribozyme.

107.
