Glutamine is one of the 20 naturally occuring amino acids. It can be abbreviated to three letters: 'Gln' or one letter: 'Q' and can be encoded for by 2 different codons, CAA and CAG. Glutamine is a polar molecule meaning that it has an enzymatic role and can bind ligands and other DNA. Polar amino acids are found buried in a protein and can be hydrogen-bonded to other polar amino acids or to the polypeptide backbone[1][2].
