[Demonstration of plasminogen activators in the saliva of a predatory insect of the family of Reduviidae (Heteroptera)].
The study of digestive and salivary proteases of Rhapactor biparticeps, has shown that the salivary glands of this insect are rich in proteolytic enzymes, however, the gut has none. The characterisation of these enzymes on different substrates showed that they are only active on fibrinogen and plasmatic proteins which are involved in the coagulation system. Among these fibrinolytic enzymes that has been identified and characterized, are the plasminogen activators. Their unexpected presence in the entomophagic insect is discussed.
