Peptidyl transferase - Wikipedia
WebbThe peptidyl transferase is an aminoacyltransferase ( EC 2.3.2.12) as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the translation process of protein biosynthesis. [1] The peptidyl transferase is an aminoacyltransferase (EC 2.3.2.12) as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the translation process of protein biosynthesis. The substrates for the peptidyl transferase reaction … Visa mer Peptidyl transferase speeds up the reaction by lowering its energy of activation. It does this by providing proper orientation for the reaction to occur. The peptidyl transferase provides proximity, meaning that it … Visa mer • Enzyme • Transferase • Translation Visa mer Background In a ribosomal structure there are three binding sites which are P site, A site, and E site.
