[1] It is composed of 69 amino acid residue, which are cross-linked by five disulfide bridges.
It acts synergistically with oxyopinins of the same venom to increase the insecticidal effect.
[2] Both of these toxins were found to block voltage-sensitive calcium ion channels.
OxyTx2 is made up of 55 amino acid residues and has a molecular mass 6175.2 Da.
