The phospholipase A2 (PLA2) superfamily consists of a broad range of enzymes defined by
their ability to catalyze the hydrolysis of the middle (sn-2) ester bond of substrate …

The number and types of venom components that affect ion-channel function are reviewed.
These are the most important venom components responsible for human intoxication …

Na+‐channel specific scorpion toxins are peptides of 60–76 amino acid residues in length,
tightly bound by four disulfide bridges. The complete amino acid sequence of 85 distinct …

Most scorpion toxins are ligand peptides that recognize and bind to integral membrane
proteins known as ion-channels. To date there are at least 202 distinct sequences …

A novel peptide, scorpine, was isolated from the venom of the scorpion Pandinus imperator,
with anti‐bacterial activity and a potent inhibitory effect on the ookinete (ED50 0.7 μM) and …

Abstract Phospholipases A 2 (PLA 2 s) are enzymes that catalyse the hydrolysis of the sn-2
acyl bond of glycerophospholipids to produce free fatty acids and lysophospholipids …

Secreted phospholipases A2 (sPLA2s) form a large family of structurally related enzymes
which are widespread in nature. Snake venoms are known for decades to contain a …

A new antimicrobial peptide, hadrurin, was isolated from the venom of the Mexican scorpion
Hadrurus aztecus, by gel filtration on a Sephadex G‐50 column, followed by high …

Abstract Ants (Hymenoptera: Formicidae) represent a taxonomically diverse group of
arthropods comprising nearly 13,000 extant species. Sixteen ant subfamilies have …

Venom and mammalian secreted phospholipases A 2 (sPLA 2 s) have been associated with
numerous physiological, pathological, and toxic processes. So far, structurally related group …
