Enzymatic activities behind degradation of glucosinolates
PublikacjaMyrosinase (thioglucosidase, EC 3.2.1.147) is the enzyme responsible for the hydrolysis of glucosinolates (GLs). In plant tissue, myrosinase and GLs are sequestered in separate cellular compartments. As a result of cell disruption, e.g., after pathogen attack or on chopping or grinding during food preparation, the myrosinase comes into contact with GLs and catalyzes the hydrolysis of thioglucosidic bond in GL structure. Consequently,...

Bioconversion of waste materials to hydrogen via dark fermentation using Enterobacter aerogenes
PublikacjaHydrogen can be obtained via dark fermentation with the use of anaerobic Enterobacter aerogenes. The efficiency of hydrogen production by fermentation techniques is strongly dependent on the con-ditions used i.e. the pH range, temperature, composition of fermentation broths, oxygen content, or even the presence of substances with potentially inhibitory effects on the microbiological culture [1-4]. The paper describes the study...

Interactions of selected mono- and disaccharides with precipitated calcium carbonate particles
PublikacjaCalcium carbonate is a widespread compound in nature and it can be produced by living organisms in the biomineralization process. Calcite, aragonite and vaterite are anhydrous polymorphic forms of calcium carbonate, wherein the calcite is the most thermodynamically stable. Vaterite is the metastable crystalline phase, which can be a precursor of calcite and aragonite, because it can easily transformed by dissolution and re crystallization...

T cell Activation Is Driven by an ADP-Dependent Glukosinase Linking Enhanced Glycolysis with Mitochondrial Reactive Oxygen Species Generation
PublikacjaMitochondria-originating reactive oxygen species control T cell receptor (TCR)-induced gene expression. Here, we show that TCR-triggered activation of ADP-dependent glucokinase (ADPGK), an alternative, glycolytic enzyme typical for Archaea, mediates generation of the oxidative signal. We also show that ADPGK is localized in the endoplasmic reticulum and suggest that its active site protrudes toward the cytosol. The ADPGK-driven...
