in a survey carried out to establish the incidence of erythrocyte glucose 6-phosphate-dehydrogenase deficiency, 738 professional blood donors of tehran were examined. the fluorescent spot technique was used for screening and qualitative determination of g-6-pd in erythrocytes. this technique was compared with other methods of g-6-pd enzyme assay and proved to be very reliable. qualitative enzy...
What is the relationship between enzymes and metabolites, the two major constituents of metabolic networks? We propose three alternative relationships between enzyme capacity and metabolite concentration alterations based on a Michaelis-Menten kinetic; that is enzyme capacities, metabolite concentrations, or both could limit the metabolic reaction rates. These relationships imply different corr...
Reconstructing metabolic and signaling pathways is an effective way of interpreting a genome sequence. A challenge in a pathway reconstruction is that often genes in a pathway cannot be easily found, reflecting current imperfect information of the target organism. In this work, we developed a new method for finding missing genes, which integrates multiple features, including gene expression, ph...
Recent single-molecule experiments reveal that mechanical tension on DNA can control both the speed and direction of the DNA polymerase motor. We present a theoretical description of this tension-induced "tuning" and "switching." The internal conformational states of the enzyme motor are represented as nodes, and the allowed transitions between states as links, of a biochemical network. The mot...
ceruloplasmin (cp) is a human plasma protein with multiple physiological functions including ferroxidase and oxidase activities. deficiency or inhibition of the enzyme may lead to some abnormalities, including iron deposition in several tissues and causes various pathological conditions in the body. direct interaction of cadmium (cd), a widespread, highly toxic environmental pollutant, with hum...
the present study was laid out in order toevaluate the effect of salinity on some biochemical characterize of grapevine c.vyaghouti. the experiment was done at agricultural and natural resources research center, ilam, iran at 2014. the experiment was a completely block design (crd) with four replications. saline factor was nacl salinity in seven levels (zero, 50, 100, 150, 200 and 250 mm). grap...
