Application
L-Homoarginine may be used to create non-natural proteins for studies of post-translational protein modifications. Arginine residues are often located at the active centers of proteins and enzymes. Replacing these arginines with homoarginine can elucidate protein function and structural requirements. L-Homoarginine is used to study the mechanisms of nitric oxide production by cells via nitric oxide synthase(s). L-Homoarginine is used as a selective mammalian alkaline phosphatase isoenzyme inhibitor. The substitution of homoarginine for arginine or lysine renders proteins resistant to proteolysis by trypsin.

Biochem/physiol Actions
Homoarginine is an inhibitor of tissue nonspecific alkaline phosphatase (TNALP). It is also an inhibitor of cellular transport of arginine by a sodium-independent high affinity y+ transporter.

Arginine analogs were incorporated site-specifically into proteins using an in vitro translation system. In this system, mRNAs containing a CGGG codon were translated by an aminoacyl-tRNA(CCCG), which was charged with arginine analogs using yeast arginyl-tRNA synthetase.
