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 sorted enzyme substrate polypeptide composed of five amino acids and a pair of fluorescent quenching units, specifically the C-terminal sorting signal. Sorting enzymes cleave surface proteins at the LPXTG motif and catalyze the formation of an amide bond between the carboxyl group of threonine and the amino group of the cell wall transpeptidation bridge. Sorting enzymes belong to the Gram-positive transpeptidase family, responsible for anchoring surface protein virulence factors to the peptidoglycan cell wall layer. The cleavage of this FRET substrate by sorting enzymes exhibits a fluorescent signal with Abs/Em = 340/490 nm.
