Microplate-based method to screen inhibitors of isozymes of cyclic nucleotide phosphodiesterase fused to SUMO.
J. Enzyme Inhib. Med. Chem. 29(6) , 836-9, (2014) The feasibility for microplate-based screening of inhibitors of isozymes of cyclic nucleotide phosphodiesterase (PDE) was tested via the coupled action of a phosphatase on adenosine-5'-monophosphate and an improved malachite green assay of phosphate. Human fu... |

Assessment of the enzymatic activity and inhibition using HPFA with a microreactor, trypsin, absorbed on immobilized artificial membrane.
J. Chromatogr. Sci. 48(2) , 150-5, (2010) The purpose of this study was to develop a new method to assess the activity and inhibition of the immobilized enzyme trypsin based on the frontal analysis of enzymatic reaction products. This novel technique was performed by on-line monitoring of the absorpt... |

Determination of the cytotoxic effect of Clostridium histolyticum culture supernatant on HeLa cells in the presence of protease inhibitors.
FEMS Immunol. Med. Microbiol. 45(2) , 137-42, (2005) Clostridium histolyticum culture supernatant contains numerous enzymes, which exert a cytotoxic effect on host cells. This includes lethal toxin, clostripain and high-potassium-sensitive toxin. Since the number of C. histolyticum infections increased during t... |

Longistatin is an unconventional serine protease and induces protective immunity against tick infestation.
Mol. Biochem. Parasitol. 182(1-2) , 45-53, (2012) Classical serine proteases use the conserved Ser/His/Asp catalytic triad to hydrolyze substrates. Here, we show that longistatin, a salivary gland protein with two EF-hand domains from the vector tick Haemaphysalis longicornis, does not have the conserved cat... |

Esterase inhibition in tadpoles of Scinax fuscovarius (Anura, Hylidae) as a biomarker for exposure to organophosphate pesticides.
Environ. Sci. Pollut. Res. Int. 17(8) , 1411-21, (2010) Organophosphate pesticides (OPs) are among the most used insecticides in agriculture, causing the inhibition of esterases like acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and carboxylesterase (CbE). Pesticides can reach the aquatic environment, ... |

Purification, characterization and substrate specificity of a trypsin from the Amazonian fish tambaqui (Colossoma macropomum).
Biochem. Biophys. Res. Commun. 396 , 667-673, (2010) An enzyme was purified from the pyloric caecum of tambaqui (Colossoma macropomum) through heat treatment, ammonium sulfate fractionation, Sephadex G-75 and p-aminobenzamidine-agarose affinity chromatography. The enzyme had a molecular mass of 23.9 kDa, NH(2)-... |

Molecular characterization of two novel isoforms and a soluble form of mouse CLEC-2.
Biochem. Biophys. Res. Commun. 371(2) , 180-4, (2008) CLEC-2 was first identified by sequence similarity to C-type lectin-like molecules with immune functions. Recently, human CLEC-2 has been reported as a receptor for the platelet-aggregating snake venom toxin rhodocytin and the endogenous sialoglycoprotein pod... |

CD38 cleavage in fMLP- and IL-8-induced chemotaxis is dependent on p38 MAP kinase but independent of p44/42 MAP kinase.
Cell. Signal. 17(2) , 167-75, (2005) In this study, we examined the mechanism by which CD38 cleavage is regulated through the mitogen-activated protein (MAP) kinases after stimulation by fMLP and interleukin-8 (IL-8) in neutrophils. Both fMLP and IL-8 increased chemotaxis and decreased CD38 prot... |

Isolation, characterization and molecular cloning of a lipolytic enzyme secreted from Malassezia pachydermatis.
FEMS Microbiol. Lett. 256(1) , 137-44, (2006) Lipophilic Malassezia species may induce catheter-associated sepsis in premature neonates and immunocompromised patients receiving parenteral lipid emulsions. To assess the participation of lipolytic enzymes in the pathogenesis of this yeast, we cloned a gene... |

A thermoactive uropygial esterase from chicken: Purification, characterisation and synthesis of flavour esters
Int. J. Biol. Macromol. 50(5) , 1238-44, (2012) A lipolytic activity was located in the chicken uropygial glands, from which a carboxylesterase (CUE) was purified. Pure CUE has an apparent molecular mass of 50kDa. The purified esterase displayed its maximal activity (200U/mg) on short-chain triacylglycerol... |
