Glutamine synthetase from Salmonella typhimurium has 23 helix-helix interactions involving helices of chain A and four different types of interactions.

Also, uncharged polar groups are usually classified as hydrophilic that is found on the outside of proteins, but for glutamine in Salmonella typhimurium its side chain is uncharged and formed by replacing the hydroxyl of glutamic acid with an amine functional group.

is within uncharged polar <insert wiki showing the uncharged polar groups>. Usually, uncharged polar groups are classified as hydrophilic <insert wiki showing the hydrophilic> that is found on the outside of proteins. Also, amino acids with the character of acidic or basic side chains are polar, showing on the outside of molecules <insert wiki showing the polar>. For glutamine, its side chain is uncharged and formed by replacing the hydroxyl of glutamic acid with an amine functional group. [http://en.wikipedia.org/wiki/Glutamine] In the other hand, glutamine has no side chain on non-polar group, however the side chain on non-polar groups of the proteins usually tends to be hydrophobic <insert wiki showing the hydrophobic of cysteine> and to cluster together on the inside.[http://www.bmb.uga.edu/wampler/tutorial/prot3.html]
