Description：DABCYL-LPETG-EDANS是一种有生物活性的肽。DABCYL-LPETG-EDANS是由5个氨基酸和一对荧光淬灭组合组成的分选酶底物多肽，即 C 端分选信号。分选酶在 LPXTG 基序处裂解表面蛋白，并催化苏氨酸的羧基与细胞壁跨桥的氨基之间形成酰胺键。分选酶是革兰氏阳性转肽酶家族，负责将表面蛋白毒力因子锚定到肽聚糖细胞壁层。分选酶对该 FRET 底物的切割显示了荧光信号，Abs/Em = 340/490 nm。

DABCYL-LPETG-EDANS is a bioactive peptide. DABCYL-LPETG-EDANS is a sorting enzyme substrate peptide composed of 5 amino acids and a pair of fluorescence quenching combinations, namely the C-terminal sorting signal. Sorting enzymes cleave surface proteins at the LPXTG motif and catalyze the formation of amide bonds between the carboxyl group of threonine and the amino group across the cell wall bridge. Sorting enzymes are a family of Gram positive transpeptidases responsible for anchoring surface protein virulence factors to the peptidoglycan cell wall. The cleavage of the FRET substrate by the sorting enzyme showed a fluorescence signal, Abs/Em=340/490 nm.
