title: Two kinins isolated from an extract of the venom reservoirs of the solitary wasp Megascolia flavifrons.
abstract: From an extract of the venom reservoirs of the wasp Megascolia flavifrons two kinins have been isolated. The sequences of amino acids are: Arg-Pro-Pro-Gly-Phe-Thr-Pro-Phe-Arg (Thr6-bradykinin) and Arg-Pro-Pro-Gly-Phe-Thr-Pro-Phe-Arg-Lys-Ala (Thr6-bradykinin-Lys-Ala). The bradykinin-like effects of the venom on a number of vertebrate smooth muscle preparations can be explained by the actions of these kinins.
