A PF07951 Toxin_R_bind_C Clostridium neurotoxin, C-terminal receptor binding Domain The Clostridium neurotoxin family is composed of tetanus neurotoxins and seven serotypes of botulinum neurotoxin. The structure of the botulinum neurotoxin reveals a four domain protein. The N-terminal catalytic domain (Pfam:PF01742), the central translocation domains and two receptor binding domains [1]. This domains is the C-terminal receptor binding domain, which adopts a modified beta-trefoil fold with a six stranded beta-barrel and a beta-hairpin triplet capping the domain [1]. The first step in the intoxication process is a binding event between this domains and the pre-synaptic nerve ending [1]. PFAM PF07951
A PF07953 Toxin_R_bind_N Clostridium neurotoxin, N-terminal receptor binding Domain The Clostridium neurotoxin family is composed of tetanus neurotoxin and seven serotypes of botulinum neurotoxin. The structure of the botulinum neurotoxin reveals a four domain protein. The N-terminal catalytic domain (Pfam:PF01742), the central translocation domains and two receptor binding domains [1]. This domains is the N-terminal receptor binding domain,which is comprised of two seven-stranded beta-sheets sandwiched together to form a jelly role motif [1]. The role of this domain in receptor binding appears to be indirect. PFAM PF07953
