7-Amino-4-methylcoumarin-3-acetic acid 是荧光蛋白质标记剂，能够被紫外光 (350 nm) 激活，可在蓝色区域 (440-460 nm) 发光。

7-Amino-4-methylcoumarin is more suitable as a substrate for enteropeptidase than GD(4)K-NA.

In this study, we used shift in the emission spectrum of GD(4)K-conjugated 7-Amino-4-methylcoumarin (GD(4)K-AMC) as a fluorogenic method to measure enteropeptidase activity. The kinetic analysis revealed that enteropeptidase has a K(M) of 0.025 mM and a k(cat) of 65 sec(-1) for 7-Amino-4-methylcoumarin, whereas it has a K(M) of 0.5 to 0.6 mM and a k(cat) of 25 sec(-1) for GD(4)K-NA. The optimum pH of 7-Amino-4-methylcoumarin hydrolysis was pH 8.0.
