Question

Quizplus · Accepted Answer

The unusual aspect of peptidyl transferase is that it is a ribozyme, meaning that it is composed of RNA rather than protein. Most catalytic activities in protein synthesis are carried out by protein enzymes, so the fact that peptidyl transferase is an RNA enzyme is notable.
