glutamine
(= Gln; Q; 146 D)
One of the 20 amino acids commonly found (and directly coded for) in proteins. It is the amide at the g -carboxyl of the amino acid glutamate. Glutamine can participate in covalent cross-linking reactions between proteins, by forming peptide-like bonds by a transamidation reaction with lysine residues. This reaction, catalysed by clotting factor XIII stabilizes the aggregates of fibrin formed during blood-clotting. Media for culture of animal cells contain some 10 times more glutamine than other amino acids, the excess presumably acting as a carbon source.
