Description
Dabcyl-QALPETGEE-Edans is a synthetic peptide substrate for fluorescence resonance energy transfer (FRET) detection of Sortase A (SrtA) enzymatic activity. Dabcyl-QALPETGEE-Edans is labeled at both ends with the fluorescent group Edans (donor) and the quencher Dabcyl (acceptor), respectively. Dabcyl-QALPETGEE-Edans's central sequence contains a conserved motif specifically recognized by SrtA. Dabcyl-QALPETGEE-Edans demonstrates high sensitivity in vitro assays, enabling precise determination of the half-maximal inhibitory concentration of SrtA[1]
