Description：H-Glu-Ala-pNA广谱氨基肽酶及金属蛋白酶的发色底物多肽，是由两个氨基酸和荧光修饰组成的小分子多肽，H-Glu-Ala-pNA酶切后释放对硝基苯胺（pNA，λmax 405 nm），用于连续光谱法测定酶活性；H-Glu-Ala-pNA用于研究蛋白酶对 N-端 Glu 或不同肽键位置的特异性识别机制；在高温合成肽连续测定体系中，H-Glu-Ala-pNA作为模型底物用于表征重组 pseudomurein endoisopeptidase（PeiW/PeiP）活性，解决传统天然底物不稳定、耗时等问题。

H-Glu-Ala-pNA, a chromogenic substrate peptide for broad-spectrum aminopeptidases and metalloproteinases, is a small-molecule peptide composed of two amino acids and a fluorescent modification. Upon enzymatic cleavage, H-Glu-Ala-pNA releases p-nitroaniline (pNA, λmax 405 nm), enabling continuous spectrophotometric determination of enzyme activity. It is employed to investigate the specific recognition mechanisms of proteases for N-terminal Glu or distinct peptide bond positions. In high-temperature peptide synthesis systems, H-Glu-Ala-pNA serves as a model substrate to characterize the activity of recombinant pseudomurein endoisopeptidase (PeiW/PeiP), addressing issues such as instability and time-consuming processes associated with traditional natural substrates.
