Pie charts displaying the BUV quantified relative occurrence (in the percentage of total venom proteins) of the different protein families in the venom proteome of desert black cobras, W. aegyptia (Sinai Peninsula, Egypt) (panel A), W. aegyptia (Riyadh, Saudi Arabia) (panel B), and W. morgani (Çörten village, Turkey) (panel C). Major TDV-identified family member components are highlighted in each pie chart. Acronyms: 3FTx, three-finger toxin; KUN, Kunitz-type serine proteinase inhibitor-like protein; CRISP, cysteine-rich secretory protein; PLA₂, phospholipase A₂; 5′NT, 5′ nucleotidase; svNGF, snake venom nerve growth factor; PIII-SVMP, snake venom metalloproteinase of class PIII; PDE, phosphodiesterase; LAO, l-amino acid oxidase; VEGF, vascular endothelial growth factor; AcChol, acetylcholinesterase; Endo, endonucleotidase.
