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.

Background Homoarginine ( hA rg) has been shown to be cardioprotective in a model of ischemic heart failure; however, the mechanism remains unknown. hA rg can inhibit tissue-nonspecific alkaline phosphatase ( TNAP ), an enzyme that promotes vascular calcification. We

Contribution of nitric-oxide (NO) pathway to the pathogenesis of bronchial asthma (asthma) is ambiguous as NO may confer both protective and detrimental effects depending on the NO synthase (NOS) isoforms, tissue compartments and underlying pathological conditions (e.g. systemic inflammation).

Using the catalytic asymmetric Sharpless carbamate aminohydroxylation, conformationally restricted L-arginine and L-homoarginine derivatives (5-8) were prepared in good enantiomeric excess to investigate the binding requirements of L-arginine-based compounds with nitric oxide synthase. The L-arginine derivatives (5 and 6) inhibited both

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.
