ENHANCED SUBSTRATES FOR THE PROTEASE ACTIVITY OF SEROTYPE A BOTULINUM NEUROTOXIN

摘要

Substrates of botulinum toxin serotype A (BoNT A), kits comprising the substrates, and methods of using the substrates are disclosed. BoNT A cleaves SNAP-25 and the substrates that are based upon a portion of SNAP-25. Various amino acid modifications to the sequence of the peptide based on SNAP-25 are performed. Fluorescence labels that act as donors and acceptors may be added to the substrate to aid in the study of BoNT A.
