Document Summary
Intro: carboxyl terminal on first amino acid forms an ester bond with the the ester linkage and forms a peptide bond between the two amino acids; Grow n c trna, which is highly unstable; the incoming amino acid"s nh3 end attacks. 16s rrna-located in small subunit, and contains the (cid:498)shine and. Sequence identifies the start codon on the mrna, which. What factors are required for translation? signals the beginning translation: trans. Ribosome-a,p, e sites and peptidyl transferase center (where formation of peptide bonds occur) A site-amino acyl site; incoming trna binds, which allows correct positioning of charged trna in order for nucleophilic attack. P site-peptidyl site; growing peptide chain held. Elongating trna-adds on aas initiation factors (ifs)-small gtp binding proteins; when proteins perform task, they hydrolyze gtp gdp. What factors are required for translation initiation in e. coli: initiation factors: fmet-trna- special trna that can recognize the initial aug start codon; only trna that directly enter p site!
