This is the three-dimensional structure of the tRNA fMet molecule

Drag the structure with the mouse to rotate

Function:

tRNA fMet is the tRNA used for the initiation of protein synthesis. It is the fist tRNA molecule that enters the ribosome, specifically at the P site, as opposed to all other tRNAs which enter the A site. The amino acid attached to tRNA fMet is N-formylmethionine, which is the first amino acid assembled into the polypeptide chain during bacterial translation. It corresponds to the start codon, "AUG."
