title: Neurotoxic kinins from wasp and ant venoms.
abstract: Kinins are polypeptides of 9-18 amino-acid residues containing a bradykinin-like sequence, in some cases as part of a molecule. The bradykinin-like sequence is either bradykinin, Hyp3-bradykinin or Thr6-bradykinin. Kinins are neurotoxic components of wasp and ant venoms, causing in the insect CNS a presynaptic block of the cholinergic transmission by means of an irreversible depletion, probably caused by a non-competitive inhibition of choline uptake.
