A chromogenic substrate for direct and continuous assay of arginase (Km = 1.6 mM, kcat = 0.09 min-1) with a detection limit of ~1 µg/ml. Arginase hydrolyzes NGB to yield urea plus the chromophore m-nitroaniline (λ = 372 nm, ε = 1,280 M-1cm-1). Although the kcat value for NGB hydrolysis is much lower than arginine, the Km value (1.6 mM) is nearly identical to arginine (Km = 1.4 mM).
