Definitions

  • FIG. 5 shows modified Clostridial toxins with an enhanced translocation capability and an altered targeting activity located between two other domains.
  • FIG. 5A depicts the single polypeptide form of a modified Clostridial toxin with an amino to carboxyl linear organization comprising an enzymatic domain, an altered targeting domain, a translocation domain and a translocation facilitating domain, with the di- chain loop region depicted by the double SS bracket.
  • a proteolytic cleavage site (P) within a di-chain loop region is located between the enzymatic and targeting domains. Upon proteolytic cleavage with a P protease, the single chain form of the toxin is converted to the di-chain form.
  • P proteolytic cleavage site
  • the H N domain also forms a long unstructured loop called the 'translocation belt,' which wraps around a large negatively charged cleft of the light chain that blocks access of the zinc atom to the catalytic-binding pocket of active site.
  • the H c domain comprises two distinct structural features of roughly equal size that indicate function. The first, designated the H CN domain, is located in the amino half of the H c domain. The H CN domain forms a ⁇ -barrel, jelly-roll fold. The H C c domain is the second domain that comprises the H c domain.
