Enzyme required for peptide formation is
Open in App
Solution
The correct option is A Peptidyl transferase
Peptidase is a class of enzymes that digest the proteins by hydrolysis of the peptide bonds that join amino acids together in a polypeptide, for example, trypsin and carboxypeptidases A and B. The peptidyl transferase forms peptide bond between the carboxyl group of peptidyl-tRNA present at P site and free amino group of peptidyl-tRNA present at A site. Digestion of ingested proteins in the stomach and small intestine is carried out by proteases which are mostly synthesized as inactive zymogens. Nitrate reductase is a multi-domain enzyme which consists of prosthetic groups molybdopterin, Fe-heme, and FAD and carries out an electron transfer from NAD(P)H to nitrate thereby reducing nitrate to nitrite. Nitrogen fixing organisms fix atmospheric nitrogen gas using nitrogenases enzymes. Option B is the correct answer.
