    Trehalase
    Opis:
    Trehalase (α, α-trehalose-1-C-glucohydrolase, EC 3.2.1.28) is a glycoside hydrolase enzyme that catalyzes the conversion of trehalose to glucose. Trehalose hydrolysis by trehalase enzyme is an important physiological process for various organisms, such as fungal spore germination, insect flight, and the resumption of growth in resting cells. So by studying biochemical properties of trehalase we can control the spore germination of harmful fungus, Apergillus niger. Till now trehalase has been reported from many other organisms including plants and animals, Trehalase has been purified and characterized from various organisms such as Saccharomyces cerevisiae, Lentinula edodes, Acidobacterium capsulatum, and Medicago sativa, as well as root nodules of Phaseolus vulgaris, soybean and from the from the seeds of Triticum aestivum. In this study, trehalase was purified from Aspergillus niger grown on cellulosic medium. And this purified trehalase was tested for various requirements it may need for enzymatic activity such as inorganic phosphate and Magnesium ions (Mg2+).

    Opis:
    Background: Different pathological affections of the small intestine cause corresponding morphological and functional changes. The present study was aimed to assess intestinal trehalase activities during ischemia and following reperfusion, correlate them with the pathological changes and determine whether trehalase could be used as a biochemical marker of the intestinal ischemia, ischemia - reperfusion injury. Material and methods: Wistar rats, randomly divided into 5 experimental groups (IR) (each n=15), were subjected to one hour mesenteric ischemia followed by 0, 1, 4, 12 and 24 hours of reperfusion. As a control group sham operated animals were used (n=15). The activity of trehalase was determined using an adapted Dahlqwist method. The range of intestinal injury was determined using histological (histopathological injury index and goblet cell quantification) and immunohistochemical (Ki67, InSitu TUNEL) methods. Results: The highest activities of trehalase were recorded in the control group (C=4.42±0.373 μmol/mg/h). The most altered intestinal histology detected in group IR1 was accompanied by the lowest trehalase activity (IR1=0.97±0.209 μmol/mg/h; p < 0.001 C vs. IR1). Improved histological structure in the remaining reperfusion periods correlated with increase in trehalase activity. Almost normal mucosal histological architecture and 72% of the enzymatic activity were restored after 24 hours of reperfusion (IR24=3.20±0.266 μmol/mg/h; p < 0.01 IR1 vs. IR24). Conclusion: The correlation between intestinal histology and trehalase activities during intestinal injury has been shown. Trehalase activity is closely associated with the status of the histological architecture of the small intestine.

    Opis:
    Introduction. The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on metabolism of glycogen and trehalose of the host was studied. Material and methods. Last instar larvae (L₇) of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae. At 6, 12, 18 and 24 h after infection concentrations of trehalose and glycogen as well as activity of trehalase and α-amylase were determined. Results. The content of glycogen was lower in insects infected with S. feltiae than in the controls and animals infected with S. affinis. The content of trehalose was higher in insects from both infected groups than in the controls. Its concentration was slightly higher in larvae infected with S. affinis than in those infected with S. feltiae. The activity of α-amylase after infection with S. affinis was low. It was significantly higher in insects infected with S. feltiae. In animals of both infected groups, following a significant reduction at 6 h, the activity of trehalase remained at a similar level, higher than in the controls. In the paper the effects of infection with (i) different species of entomopathogenic nematodes and (ii) the importance of the developmental stage of the insect-host for changes in its metabolism of glycogen and trehalose were discussed.

    Opis:
    The experimental studies were conducted on caterpillars of wax moth Galleria mellonella infected with Steinernema affinis larvae. The concentration of trehalose and the activity of trehal ase were measured during the invasion lasting 48h. The level of trehalose and activity of enzyme were slightly lower in infected insects in comparison to the control animals.
