ADAM substrate containing the fluorophore quencher Dabcy is used in FRET applications for detection of metalloprotease activity. DABCYL is a popular acceptor for developing FRET-based protease substrates. DABCYL dyes are often paired with EDANS in FRET-based fluorescent probes.
Combinatorial chemistry & high throughput screening, 13(4), 358-365 (2009-12-18)
Fluorescence resonance energy transfer substrates were designed and tested as substrates for ADAM9. The donor/quencher pair used were 5-carboxy fluorescein (Fam) and 4-(4-dimethyl-aminophenylazo)benzoyl (Dabcyl) since they have been well studied sensitive fluorescent probes. The peptides based on precursor TNF-alpha, Dabcyl-Ser-Pro-Leu-Ala-Gln-Ala-Val-Arg-Ser-Ser-Lys(Fam)-
In this paper we describe novel fluorescent substrates for the human ADAM family members ADAM17, ADAM10, ADAM8, and ADAM12 that have good specificity constants and are useful for high-throughput screening of inhibitors. The fluorescence resonance energy transfer substrates contain a
Tumor necrosis factor-alpha (TNFalpha) is presumably shed from cell membranes by TNFalpha-cleaving enzyme (TACE). The peptides SPLAQAVRSSSR and Dabcyl-LAQAVRSSSR-Edans, each encompassing the cleavage sequence of pro-TNFalpha recognized by TACE, were applied to intact umbilical vein endothelium (HUVEC), peripheral blood leukocytes
Characterization of Mca-Lys-Pro-Leu-Gly-Leu-Dpa-Ala-Arg-NH2, a fluorogenic substrate with increased specificity constants for collagenases and tumor necrosis factor converting enzyme.
