- The small ribosomal subunit binds to several initiation factors (IF1, 2, 3);
this complex binds to mRNA.
- Initiator tRNAfmet binds to mRNA
AUG codon in the
P (peptidyl) site
GTP is hydrolyzed to provide energy for the reactions.
Large subunit binds to complex. Elongation factor Tu binds to the next tRNA,
facilitating entry into the
A (aminoacyl) site.
