The enzyme that catalyses peptide bond formation is located in

Question

The enzyme that catalyses peptide bond formation is located in (A) In DHU loop of tRNA (B) Smaller subunit of ribosome (C) Larger subunit of ribosome (D) On mRNA

Tardigrade Admin · Accepted Answer

Peptide bond formation is catalyzed by enzyme peptidyl transferase which is a ribozyme. High molecular weight rRNA, 23S in prokaryotes, and 28S in eukaryotes function as a ribozyme. These rRNAs are located in a larger subunit of the ribosome at P site.
