Alignment of TFPI-like sequences. The putative Protobothrops TFPI transcript [AB851921] is most similar to a DNA sequence from Anolis carolinensis. It aligns best at the C-terminus and in the middle, except for a 27-residue deletion in the Protobothrops sequence, which separates these two regions. Two partial transcripts from Ovophis venom glands [AB851997, AB851998] are identical to that from Protobothrops in the middle section. Affinities of these toxins to bovine pancreatic trypsin inhibitor and to the Ku-Wap fusion toxin from Sistrurus catenatus edwardsi venom are weak.
