Description

FRET-based peptide substrate for detection of protease activity of coronaviruses

  • CoV Protease Substrate-1 EDANS allows for efficient detection of coronavirus (CoV) proteases
  • This fluorescence resonance energy transfer (FRET)-based peptide substrate can be cleaved by 3C-like protease (3CLpro), the CoV main protease involved in regulating the coronavirus replication complex
  • 3CLpro is also a potential target for therapeutic applications
  • CoV Protease Substrate-1 EDANS has an excitation wavelength of 336 nm, an emission wavelength of 455 nm, and an extinction coefficient of 5900 cm-1 M-1
  • It consists of a 14 amino acid sequence (KTSAVLQSGFRKME) that also contains the DABCYL (quencher) and EDANS (donor) fragments at the N- and C- termini, respectively
  • When the peptide substrate is intact, favorable energetic overlap of the EDANS excited state and the DABCYL absorption leads to efficient intramolecular fluorescence quenching of EDANS by the DABCYL fragment
  • Cleavage of the substrate by CoV proteases, however, dissociates the EDANS fragment from DABCYL, restoring the fluorescence of the EDANS moiety that is directly correlated to the CoV protease activity
