Overview of protein synthesis
Before protein synthesis
tRNA with growing peptide in the P site;
aminoacyl-tRNA in the A-site
Peptide bond formation
Involves transfer of polypeptide from
peptidyl-tRNA in P-site to aminoacyl-tRNA
in A-site
Translocation
Moves ribosome one codon; places
peptidyl-tRNA in P-site; deacylated tRNA
leaves the ribosome; A site is empty
