The peptidyl transferase is a component of
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. The A site is the … Visa mer The following protein synthesis inhibitors target peptidyl transferase: • Chloramphenicol binds to A2451 and A2452 residues in the Visa mer • Peptidyl+transferases at the U.S. National Library of Medicine Medical Subject Headings (MeSH) Visa mer WebbThe position of an amino acid within a polypeptide is determined by the binding of mRNA with a tRNA carrying a specific amino acid.
