Question

Which of the following molecule catalyzes the transpeptidation reaction?
A.RNA polymerase
B. Peptidyl transferase
C. DNA ligase
D. DNA polymerase

Answer 1

Answer:

B. Peptidyl transferase

Answer 2

Peptidyl transferase is the molecule that catalyzes the transpeptidation reaction.

• Peptidyl transferase is an aminotransferase that has enzymatic functions which function more in the ribosomes.

• It is a crucial enzyme as it helps in the formation of peptide bonds.

• These bonds are found between two amino acids. The joining of amino acids will result in the formation of protein.

• It lowers the energy of activation in order to speed up the reaction.

• It helps in bringing amino acid molecules closer.
