The combinations of gel electrophoresis or LC and mass spectrometry are two popular approaches for large scale protein identification. However, the throughput of both approaches is limited by the speed of the protein digestion process. Present research into fast protein enzymatic digestion has been focused mainly on known proteins, and it is unclear whether these results can be extrapolated to ...

background: varicella zoster virus (vzv) causes chickenpox in children and zoster (zona) in the elderly. using rflp-pcr method for detection of vzv specific snps orf38, 54 and 62 could  distinguish the profile of vzv isolates. the aim of this study was to investigate enzymatic digestion pattern of vzv orf38 and orf54 in chickenpox patients using rflp technique. methods: thirty-eight chickenpox ...

Background Spontaneous abortion has been defined as two or more consecutive miscarriages at 20 weeks pregnancy. Vascular endothelial growth factor (VEGF) plays a main role in fetal and placental angiogenesis which secretes from different cells like endometrium and placenta.The objective of this study was to investigate of association of VEGFA gene polymorphisms and recurrent spontaneous abortio...

Abstract Protein digestibility of soybean obtained from the main manufacturing steps for natto, such as soaking (soaked soybeans ‘S’), boiling (boiled ‘B’), and fermentation (fermented ‘F’), was examined in this study. Biochemical indices processed each step those digested fractions by simulated vitro gastrointestinal digestion were also evaluated. The result showed a significant ( P < 0.05)...

in biological wastewater treatment large quantities of sludge are produced. this sludge is highly putrescible.for disposal and safe usage should be stabilized. the anaerobic digestion is a standard technique for stabilization. due to the rate imiting step of sludge hydrolysis, anaerobic degradation is a slow process with high digestion time. due to high retention time and sludge dewatering prob...

A staphylococcal nuclease (strain Foggi), very similar in chemical structure to the enzyme from strain V8, is cleaved in a limited way by trypsin in the presence of deoxythymidined/,5’-diphosphate and Ca++. Such treatment yields fragments PI (residues 1 to 5), PZ (residues 6 to 48), P3 (Psa, residues 49 to 149; and P3b, 50 to 149), and free lysine (residue 49). None of the products shows enzyma...

Digestion of polyoma viral DNA with a restriction enzyme from Haemophilus aegyptius generates at least 22 unique fragments. The fragments have been characterized with respect to size and physical order on the polyoma genome, and the 5' to 3' orientation of the (+) and (-) strands has been determined. A method for specific radiolabeling of adjacent fragments was employed to establish the fragmen...

Analysis of products digested by glycosyl hydrolases helps understanding of the hydrolysis mechanism and the substrate recognition in the enzymes. We developed a new universal technique, which consists of ruthenium (II) complex labeling and mass spectrometry analysis, to identify the reducing sugars released from oligosaccharides by enzymatic digestion. This method was applied to enzymatic dige...
