Ophiophagus hannah (king cobra) (taxid:8665)

Venom composition

Figure 1: Composition of O. hannah venom, studied at proteomic level (Vonk et al., 2013). This venom contains the following families: 3FTx (snake three-finger toxin), SVMP (snake venom metalloproteinase), CRISP, PA2 (phospholipase A2), CVF (cobra venom factor of the venom complement C3 homolog family), VEGF (PDGF/VEGF growth factor), LAAO (Flavin monoamine oxidase (L-amino-acid oxidase) ), NP (natriuretic peptide), PDE (phosphodiesterase), vespryn (ohanin/vespryn), kallikrein, Kunitz (venom Kunitz-type). Transcriptome of the venom and accessory glands are also available as pie charts in Fig.1 of Vonk et al., 2013.
