why methionin act as first aminoacid in protein synthesis?

Answer Posted / guest

The methionine when it is attached to the initiator
methionine tRNA, can be formylated.

The formylation of the methinoine blocks the amino group of
the methionine and prevents it from any reaction on the
amino side and allows it to bind only to the P-site.

Subsequently the second amino acyl-tRNA enters at the A site
and the peptide bond is formed between the two amino acids.

Subsequently the second amino acyl-tRNA enters at the A site
and the peptide bond is formed between the two amino acids.

In eukaryotes the initiator tRNA itself is mutated and
so binds only to the P-site and thus there is no need for it
to be formylated.

After initiation of protein synthesis, the methionine is
cleaved off by an enzyme, since it is not present in the
mature polypeptide.
