Descripción

Descripción

  • CoV Protease Substrate-1 TF5 allows for efficient detection of coronavirus (CoV) proteases
  • This fluorescence resonance energy transfer (FRET)-based peptide substrate is cleaved by 3C-like proteases (3CLpro), the CoV main protease involved in regulating the coronavirus replication complex
  • 3CLpro is also a potential target for therapeutic development
  • CoV Protease Substrate-1 TF5 has an excitation wavelength of 649 nm, an emission wavelength of 664 nm, and an extinction coefficient of 250,000 cm-1 M-1
  • It consists of a 14 amino acid sequence (KTSAVLQSGFRKME) that also contains the Tide Quencher™ 5 (TQ5; quencher) and Tide Fluor™ 5 (TF5; donor) fragments at the N- and C- termini, respectively
  • When the peptide substrate is intact, favorable energetic overlap of the TF5 excited state and the TQ5 absorption leads to efficient intramolecular fluorescence quenching of TF5 by the TQ5 fragment
  • Cleavage of the substrate by CoV proteases, however, dissociates the TF5 fragment from TQ5, restoring the fluorescence of the TF5 moiety that is directly correlated to the CoV protease activity
