N-(4-Methoxyphenylazoformyl)-Arg-OH . HCl |
Catalog No.GA23218 |
AAFR, substrate for carboxypeptidase B type enzymes. Enzymic removal of the anisylazoformyl (Aaf) moiety is followed by a decrease in substrate absorption at 350 nm (Λmax ≈ 350 nm, ε ≈ 19000 M?¹ cm?¹). The kcat/Km value for hydrolysis by porcine carboxypeptidase B at 25 °C, pH 7.9 (0.05 M Tris buffer) was 1.0 x 10? s?¹ M?¹. AAFR has been used to measure the TAFI (thrombin activatable fibrinolysis inhibitor, carboxypeptidase U) activation by thrombin and thrombin-thrombomodulin.
