Figure 6: A rendering of the 3D structure of crotoxin from Crotalus durissus terrificus. A ribbon diagram of the dimeric crystal structure of crotoxin (PDB #3R0L) is illustrated to highlight the acidic subunit (left side) and to show the basic subunit (right side). 3D molecular rendering and annotations of crotoxin were performed by using the Swiss PDB Viewer software.
