Figure 4From: Insights into the evolutionary origins of clostridial neurotoxins from analysis of the Clostridium botulinum strain A neurotoxin gene clusterStructural similarity between HCRn and the NC4 domain of collagen IX. A structural superposition of the human collagen IX NC4 domain (2UUR) and the TeNT HCRn domain (1YYN) was performed using the VAST alignment algorithm http://www.ncbi.nlm.nih.gov/Structure/VAST/vastsearch.html. In the structural alignment 2UUR and 1YYN are colored pink and blue respectively.Back to article page
