C-Npys (S-3-nitro-2-pyridinesulfenyl) and peptide derivatives can inhibit a serine-thiol proteinase activity from Paracoccidioides brasiliensis
(Elsevier B.V., 2007-04-20)
The inhibitory capacity of C-Npys (S-[3-nitro-2-pyridinesulenyl]) derivatives over thiol-containing serine proteases has never been tested. in the present work we used an extracellular serine-thiol protemase activity from ...

Purification and preliminary characterization of a plasma kallikrein inhibitor isolated from sea hares Aplysia dactylomela Rang, 1828
(Elsevier B.V., 2004-02-01)
An inhibitor active against pancreatic trypsin was found in the crude extract from the sea hares Aplysia dactylomela Rang, 1828. A stronger inhibitory activity against human plasma kallikrein was detectable after treating ...
Detection of the basement membrane-degrading proteolytic activity of Paracoccidioides brasiliensis after SDS-PAGE using agarose overlays containing Abz-MKALTLQ-EDDnp
(Associação Brasileira de Divulgação Científica, 1999-05-01)
We have characterized, in the Paracoccidioides brasiliensis yeast phase, an exocellular SH-dependent serine proteinase activity against Abz-MKRLTL-EDDnp and analogous fluorescent-quenched peptides, and showed that it is ...
Biochemical and biological evaluation of gyroxin isolated from Crotalus durissus terrificus venom
(Universidade Estadual Paulista (Unesp), Centro de Estudos de Venenos e Animais Peçonhentos (CEVAP), 2011-01-01)
Gyroxin, a thrombin-like enzyme isolated from Crotalus durissus terrificus venom and capable of converting fibrinogen into fibrin, presents coagulant and neurotoxic activities. The aim of the present study was to evaluate ...
Enzymatic toxins from snake venom: structural characterization and mechanism of catalysis
(Wiley-Blackwell, 2011-12-01)
Snake venoms are cocktails of enzymes and non-enzymatic proteins used for both the immobilization and digestion of prey. The most common snake venom enzymes include acetylcholinesterases, l-amino acid oxidases, serine ...
Purification and characterization of a kinin-releasing and fibrinogen-clotting serine proteinase (KN-BJ) from the venom of Bothrops jararaca, and molecular closing and sequence analysis of its cDNA
(Springer, 1998-02-01)
Two forms of a proteinase, KN-BJ 1 and 2, were purified to homogeneity from the venom of Bothrops jararaca. in SDS/PAGE reduced KN-BJ 1 and 2 migrated as single bands with molecular masses of 38 kDa and 39 kDa. the two ...
