概述| 货号 | 80240-50mg |
| 描述 | L-Arginine serves as a common substrate for both nitric oxide synthase (NOS) and arginase in the cell. NOS catalyzes the oxidation of arginine to citrulline and NO with Nω-hydroxy-L-arginine (NOHA) formed as an intermediate. Arginase, on the other hand, catalyzes the hydrolysis of arginine into urea and L-ornithine. Thioarginine (hydrobromide) is a colorimetric substrate for arginase that provides the basis for continuous spectrophotometric measurement of enzyme activity.1 It exhibits Km and kcat values of 0.5 mM and 18,000 min−1, respectively, which are similar to physiological substrate arginine.1 The thiol product of the reaction reacts with DTNB to produce 2-nitro-5-thiobenzoate for easy visualization at 405-420 nm. |
