At Which Site Does Charged Initiator Trna Bind During Protein Synthesis

At which site does the charged initiator tRNA bind during protein synthesis?


P site

The initiator tRNAfmet binds to the mRNA codon in the P site of the ribosome. The initiator tRNA is the only one that binds in the P site; all other tRNAs bind the ribosome in the A site.

This is the site at which charged tRNAs complementary to the mRNA codon in the A site enter the ribosome.
