Identification of bradykinins in solitary wasp venoms
(Elsevier B.V., 2002-03-01)
Bradykinins were identified in three solitary wasp venoms. Purification and characterization of the venom extract of the scoliid wasp Megacampsomeris prismatica led to the identification of bradykinin and threonine(6)-bradykinin ...
High-performance gel filtration patterns of venoms from three species of wasps of the genus Polybia (hymenoptera, vespidae).
(1996-01-01)
The profiles of high-performance gel filtration of venoms from Polybia paulista, Polybia ignobilis and Polybia occidentalis occidentalis showed 13 peaks distributed among the three species. These profiles presented ...
Conformation and lytic activity of eumenine mastoparan: A new antimicrobial peptide from wasp venom
(2004-09-01)
Eumenine mastoparan-AF (EMP-AF) is a novel membrane active tetradecapeptide recently isolated from the venom of solitary wasp, Anterhynchium flavomarginatum micado. It was reported previously that EMP-AF peptide presented ...
Characterization of two novel polyfunctional mastoparan peptides from the venom of the social wasp Polybia paulista
(Elsevier B.V., 2009-08-01)
Hymenoptera venoms are complex mixtures of biochemically and pharmacologically active components such as biogenic amines, peptides and proteins. Polycationic peptides generally constitute the largest group of Hymenoptera ...
Proteomic characterization of the multiple forms of the PLAs from the venom of the social wasp Polybia paulista
(Wiley-Blackwell, 2011-04-01)
The phospholipases A(1) (PLA(1)s) from the venom of the social wasp Polybia paulista occur as a mixture of different molecular forms. To characterize the molecular origin of these structural differences, an experimental ...
Proteomic Characterization of the Hyaluronidase (EC 3.2.1.35) from the Venom of the Social Wasp Polybia paulista
(Bentham Science Publ Ltd, 2012-06-01)
Polybia paulista wasp venom possesses three major allergens: phospholipase A(1), hyaluronidase and antigen-5. To the best of our knowledge, no hyaluronidase from the venom of Neotropical social wasps was structurally ...
Two new bradykinin-related peptides from the venom of the social wasp Protopolybia exigua (Saussure)
(Elsevier B.V., 2006-11-01)
Two bradykinin-related peptides (Protopolybiakinin-I and Protopolybiakinin-II) were isolated from the venom of the social wasp Protopolybia exigua by RP-HPLC, and sequenced by Edman degradation method. Peptide sequences ...
Profiling the peptidome of the venom from the social wasp Agelaia pallipes pallipes
(Elsevier B.V., 2011-09-06)
The wasp Agelaia pallipes pallipes is one of the most aggressive species from the neotropical region, causing many stinging accidents every year, characterized by severe envenoming reactions. The identification of peptides ...
Structure-function relationships of the peptide Paulistine: A novel toxin from the venom of the social wasp Polybia paulista
(2014-01-01)
Background: The peptide Paulistine was isolated from the venom of wasp Polybia paulista. This peptide exists under a natural equilibrium between the forms: oxidised - with an intra-molecular disulphide bridge; and reduced ...
