Glutathion-S-Transferasen (GSTs) entgiften gewöhnlich Fremdstoffe. Der Pilz Aspergillus fumigatus nutzt jedoch die GST GliG, um zwei Schwefelatome in seinen Virulenzfaktor Gliotoxin einzufügen. Wir beschreiben Strukturen von GliG mit Glutathion (GSH) sowie dem Reaktionsprodukt zyklo[-l-Phe-l-Ser]-bis-Glutathion, welches aus einem genetisch modifizierten Aspergillus-fumigatus-Stamm gewonnen wurd...

Non-thermal inactivation of courgette peroxidase enzyme: Response surface modeling the effect cumin, fennel and clove essential oils

abstract kinetic properties of root of peroxidase of gundelia tournefortii investigated at different ph, temperature and different inhibitors. maximum activity of peroxidase achieved at ph 5.5-6 in according to type of substrate. activity of peroxidase increased at constant concentration of h2o2 and different concentration of guaiacol, catechol and pyrogallol. the maximum activity in presence o...

In this study, the synthesis of ceria (CeO2) nanoparticles (NPs) was examined by the biosynthesis method. Then, enzyme-like features of synthesized nanoceria were examined. Peroxidase enzyme from fig (Ficus carica) was used as a synthesis and stabilizer reagent. Furthermore, it was investigated whether the obtained nanoceria has superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX) ac...

Members of the multidrug resistance protein (MRP/ABCC) subfamily of ATP-binding cassette proteins transport a wide array of anionic compounds, including sulfate, glucuronide, and glutathione (GSH) conjugates. The present study tested the ATP-dependent vesicular transport of leukotriene C(4) and 17beta-estradiol 17-(beta-d-glucuronide) (E(2)17betaG) mediated by the MRP1 and MRP2 transporters in ...

Peroxidase (POD) associated with the browning of fresh-cut fruits and vegetableswas extracted from purple skin eggplant(Solanum melongena L.) characterised using reliable spectrophotometric methods. Maximal POD activity was found at 35 °C pH 6.0 guaiacol as substrate. The enzyme stable his optimal temperature (35 °C) hisat stability in range 5.6 - 6.6.Peroxidase retained its full presence ion...
