An enzyme that is not protein in nature:
Correct answer: D. Peptidyl transferase
- A. Amylopsin
- B. Bam H1
- C. Arginase
- D. Peptidyl transferase
Explanation
Peptidyl transferase is an enzyme that is not a protein in nature. It is a ribozyme, a catalytic RNA molecule found in the ribosome. It is responsible for catalyzing the formation of peptide bonds during protein synthesis. Unlike traditional enzymes that are protein-based, peptidyl transferase demonstrates the catalytic abilities of RNA molecules.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
