AB  - Diverse recombinant immunoreagents specific for TNT–derivatives were tested in different assay forms in order to analyze their specificity and sensitivity. Performance of immunoassays was based on TNP–protein conjugates immobilization on a solid surface. In this work, the detection limit for TNT–analog TNP–Tris was 250 fmol or 87 pg mL−1 (87 ppt), which represents the most sensitive assay published until now, regarding the detection of recombinant antibodies.

AB  - Variations were studied of the activity and isoenzyme patterns of soluble peroxidase, catalase, catechol oxidase and superoxide dismutase, in needles of the Balkan endemic conifer Serbian spruce, Picea omorika (Panč.) Purkinye. The samples were collected from the natural habitat of the species, Mt. Tara. Seasonal changes were found to affect enzymatic activities and isoenzyme profiles. Total protein content was significantly lower in the summer than in other seasons. Several isoforms of peroxidase, catechol oxidase and superoxide dismutase (SOD), as well as two catalase isoenzymes were detected. The number of peroxidase isoenzymes was greatest during the vegetative season. Catalase and catechol oxidase peaked in summer and spring, respectively. Total SOD and Mn-SOD activities were significantly higher in the winter samples than the summer ones.

AB  - We succeeded in the immobilization of 190 mg of periodate oxidized glucoamylase per gram of macroporous polymer. The covalently immobilized enzyme had a specific activity of 1100 U/g. The temperature and pH optimum as well as kinetic parameters were determined. The immobilized enzyme was tested in different types of reactors for hydrolysis of concentrated maltose and starch hydrolysate syrups. The DE value of 98.6, obtained the immobilized enzyme, was slightly higher than that for the soluble form, when acting on 20% substrates.During continuous use in a packed bed reactor over a period of 4 weeks the immobilized enzyme produced 1300 kg of glucose per 1 L of reactor volume without any decrease in its activity.

AB  - α-Glucosidase from S. cerevisiae was covalently immobilized onto Sepabeads EC-EA by the glutaraldehyde method. An analysis of the variables controlling the immobilization process is first presented and it is shown that the highest coupling of α-glucosidase occurred within 24 h. Also, a loading of 30 mg/g support proved to be effective, resulting in a rather high activity of around 45 U g-1 with a satisfactory degree of enzyme fixed. Both free and immobilized enzymes were then characterized by determining the activity profile as a function of pH, temperature and thermal stability. The obtained immobilized preparation showed the same optimum pH, but a higher optimum temperature compared with the soluble one. In addition, the immobilized enzyme treated at 45°C for 1 h still retained an activity of around 20 %, whereas the free enzyme completely lost its original activity under this condition. In conclusion, the developed immobilization procedure is quite simple, easily reproducible and provides a promising solution for the application of immobilized α-glucosidase.

AB  - An approach is presented for the stable covalent immobilization of Upase from Candida rugosa on Eupergit® with a high retention of hydrolytic activity. It comprises covalent bonding via lipase carbohydrate moiety previously modified by periodate oxidation, allowing a reduction in the involvement of the enzyme functional groups that are probably important in the catalytic mechanism. The hydrolytic activities of the lipase immobilized on Eupergif1 by two conventional methods (via oxirane group and via glutaralde-hyde) and with periodate method were compared. Results of lipase assays suggest that periodate method is superior for lipase immobilization on Eupergit® among methods applied in this study with respect to both, yield of immobilization and hydrolytic activity of the immobilized enzyme.
AB  - U ovom radu je ispitana mogućnost primene metode za kovalentno vezivanje lipaze iz Candida rugosa za komercijalni polimerni nosač Eupergit® kojom se dobijaju stabilni i aktivni imobilisani enzimi. Vezivanje se odvija preko ugljenohidratne komponente enzima, koja je prethodno modifikovana oksidacijom pomoću perjodata, a ne preko proteinske komponente, koja je važna za katalitičku aktivnost enzima. Hidrolitička aktivnost na ovaj način imobilisane lipaze upoređena je sa aktivnostima lipaza koje su imobilisane pomoću dve konvencionalne metode (vezivanje preko epoksidnih grupa nosača i vezivanje za nosač modifikovan glutaraldehidom). Rezultati ovog istraživanja pokazuju da je perjodatna metoda pogodnija za imobilizaciju lipaze na Eupergit® sa oba ispitivana aspekta: prinosa imobilizacije i hidrolitičke aktivnosti imobilisanog enzima.

AB  - The discovery of porosome and elucidation of its morphology, dynamics, and composition, reveled where membrane-bound secretory vesicles dock and fuse to release their contents. How membrane-bounded secretori vesicles fuse at plasa membrane-associated porosome has also been eluciated. This discovery has also revealed how little we know about the cell, and thus heralds a new revolution in cell biology, i.e. the birth of nano cell biology.

AB  - The avarone/avarol quinone/hydroquinone couple, as well as their derivatives show considerable antitumor activity. In this work, covalent modifications of β-lactoglobulin, isolated from cow milk, by avarone, its model compound 2-tert-butyl-1,4-benzoquinone, and several of their alkylthio derivatives were studied. The techniques applied for assaying the modifications were UV/VIS spectrophotometry, SDS PAGE and isoelectrofocusing. The results of the SDS PAGE suggest that polymerisation of the protein occurs. The shift of the pI of the protein upon modification toward lower values indicates that lysine amino groups are the principal site of the reaction of β-lactoglobulin with the quinines.
AB  - Hinonsko/hidrohinonski par avaron/avarol i njihovi derivati pokazuju značajnu antitumorsku aktivnost. U ovom radu proučavane su kovalentne modifikacije β-laktoglobulina, izolovanog iz kravljeg mleka, avaronom, njegovim model-jedinjenjem 2-tert-butil-1,4-benzohinonom i njihovim alkiltio-derivatima. Za ispitivanje modifikacija korišćene su UV/VIS spektrofotometrija, SDS PAGE i izoelektrofokusiranje. Rezultat SDS PAGE ukazuje da se protein polimerizuje. Pomeranje pI vrednosti proteina nakon modifikacije ka nižim vrednostima pokazuje da su amino grupe lizina glavna mesta reakcije β-laktoglobulina sa hinonima.
