Two new toxins were purified from Leiurus quinquestriatus hebraeus (Lqh) scorpion venom,
Lqh II and Lqh III. Lqh II sequence reveals only two substitutions, as compared to AaH II, the …

Scorpion venom contains a group of two-domain peptides that function to block potassium
channels or have cytolytic activities. These peptides, whose functions are poorly studied, are …

The crystal structure of the bacterial K+ channel, KcsA (Doyle, DA, Morais, CJ, Pfuetzner,
RA, Kuo, A., Gulbis, JM, Cohen, SL, Chait, BT, and MacKinnon, R.(1998) Science280, 69 …

Maurotoxin, a 34-amino acid toxin from Scorpio maurus scorpion venom, was examined for
its ability to inhibit cloned human SK (SK1, SK2, and SK3), IK1, and Slo1 calcium-activated …

BmKK4 is a 30 amino acid peptide purified from the venom of the Chinese scorpion Buthus
martensi Karsch. It has been classified as the first member of scorpion toxin subfamily α-KTx …

Scorpion toxins affecting K+ channels (KTxs) represent important pharmacological tools and
potential drug candidates. Here, we report molecular characterization of seven new KTxs in …

Background Recently, a new subfamily of long-chain toxins with a Kunitz-type fold was
found in scorpion venom glands. Functionally, these toxins inhibit protease activity and block …

Three novel peptide inhibitors of the SKCa channels were purified to homogeneity from the
venom of the scorpion Androctonus mauretanicus mauretanicus using one step of RP …

The cDNA and genomic DNA of three novel toxins from the scorpion Buthus martensi Karsch
that are active on K+ channels, designated BmKTX (where KTX is kaliotoxin), BmTX1 and …

Abstract Parabutoxin 3 (PBTx3), a short‐chain α‐K+ neurotoxin from the scorpion,
Parabuthus transvaalicus, is a 37‐residue polypeptide cross‐linked by three disulphide …
