Description：D-Val-Leu-Lys PNA·2HCl是纤溶酶和微纤溶酶的底物多肽，是由3个氨基酸组成的荧光底物。 微纤溶酶水解 D-VLK-pNA，Km 为 0.361 +/- 0.017 mM，kcat 为 40.3 +/- 3.3 s¹，而天然纤溶酶的 Km 为 0.355 +/- 0.002 mM，kcat 为 27.9 +/- 0.3 s¹（50 mM Tris-HCl，pH 7.4，0.1 M NaCl，37 °C）。

D-Val-Leu-Lys PNA·2HCl is a fluorescent peptide substrate for plasmin and microplasmin, composed of three amino acids. Microplasmin hydrolyzes D-VLK-pNA with a Km of 0.361 ± 0.017 mM and a kcat of 40.3 ± 3.3 s⁻¹, while native plasmin has a Km of 0.355 ± 0.002 mM and a kcat of 27.9 ± 0.3 s⁻¹ (50 mM Tris-HCl, pH 7.4, 0.1 M NaCl, 37 °C).
