Description
(Trifluoroacetate Form) D-A2pr(Nma)-Gly-[Phe/Ala/Val/Glu/Arg]-[Pro/Tyr/Lys/Ile/Asp]-Pro-Ala-Phe-Pro-Lys(Dnp)-D-Arg-D-Arg A2pr(Nma) : N-beta-[2-(Methylamino)benzoyl]-2,3-Diaminopropionic Acid Lys(Dnp): N-epsilon-(2,4-Dinitrophenyl)Lysine Fluorescence-Quenching Substrate Library When an enzyme of interest cleaves any peptide bond between D-A2pr(Nma) and Lys(Dnp) in the substrate, the fluorescence at Lambda ex = 340 nm and Lambda em = 440 nm increases in proportion to the release of the Nma fluorophore from the internal Dnp quencher
