Potassium Channels Blockers from the Venom of Androctonus mauretanicus mauretanicus
Figure 2
Amino acid sequences and 3D structures of P01 and P05. (a) Amino acid sequence (single letter notation) and 3D structure of P01 [26, 28]. (b) Amino acid sequence (single letter notation) of P05 compared to that of the bee venom apamin (18 mers peptide). Amino acids common to P05 and apamin and crucial for the SKCa blockade are in blue. These amino acids are materialized on the 3D structure of P05, view by the α-helix axe. The two positive Arg are in blue and the neutral Gln is in brown.
