Glutamine
Glutamine (symbol Gln or Q) is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide. It is classified as a charge-neutral, polar amino acid. It is non-essential and conditionally essential in humans, meaning the body can usually synthesize sufficient amounts of it, but in some instances of stress, the body's demand for glutamine increases, and glutamine must be obtained from the diet. It is encoded by the codons CAA and CAG.
ADAM7
Human ADAM7 contains a sequence of 756 amino acids. Numerous mammalian orthologs are currently known. The largest portion of ADAM7 resides in the extracellular space. A short helical transmembrane sequence anchors the sequence while a short cytoplasmic sequence exists. This is consistent and expected as the protein has a secretory function.
