Tityus obscurus
(Amazonian scorpion)
Venom composition
Figure 1: Composition of T.obscurus venom, studied at the transcriptomic level. This venom contains the following families (classified by activity): sodium channel toxin (NaTx), anionic peptide, anticoagulant peptide (negligible), antimicrobial peptide (AMP),
bradykinin potentiating-peptide (BPP)
, chitinase (negligible),
CRISP
, hyaluronidase, insulin-like growth factor, lipase,
metalloproreinase
,
phospholipase A2 (PA2)
, phospholipase C (negligible), potassium channel toxin (KTx), proteinase inhibitor, other proteinase, conserved venom component (
de Oliveira et al., 2018
). Families with an asterix (*) are those with peptides identified by proteomic analysis.
