[[http://www.uniprot.org/uniprot/PA2B1_BUNMU PA2B1_BUNMU]] Snake venom phospholipase A2 (PLA2) that inhibits neuromuscular transmission by blocking acetylcholine release from the nerve termini. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. [[http://www.uniprot.org/uniprot/VKTH2_BUNMU VKTH2_BUNMU]] Beta-2-bungarotoxin is a presynaptic neurotoxin of the venom. The B chain is homologous to venom basic protease inhibitors but has no protease inhibitor activity and blocks voltage-gated potassium channels (Kv).<ref>PMID:9693106</ref>
