SA11 VP7 (amino acids 190–288) is aligned with the complete sequences of two representative snake venom disintegrins, echistatin and bitistatin (32), which show 48% similarity by use of the clustal w program and 48% identity to each other. The illustrated region of SA11 is 24% similar and 19% identical to echistatin and 20% similar and 14% identical to bitistatin. Two adjacent regions of bitistatin both align to amino acids 190–207 of SA11 VP7. Stars, dots, square brackets, and triangles are defined in the legends of Figs. 1 and 2.
