Supplementary Fig. S3.

The sequences alignment of two elapid SVMPs – atragin and K-like from Naja atra with two viper SVMPs – VAP1 and VAP2. Two P-III SVMPs, atragin and K-like, from Naja atra comprise an M domain (yellow star in the bottom), a linker domain (pink star), a D domain (blue star), and a C domain (green star). Two brown squares represent two N-glycosylation sites of K-like in the M domain and in the C domain, respectively, and one cyan square represents only one N-glycosylation site of atragin in the D domain. Disulfide pairs are represented by the numbers in green.
