Mechanism of Aconitase Action
Five experiments that support this scheme are presented. 1. The conversion of 3-T-isocitrate to citrate at early times gives T-citrate with no loss of tritium. 2. When the conversion of 2-T-citrate to isocitrate is brought to completion by trapping the isocitrate with isocitrate dehydrogenase, and the oc-ketoglutarate formed with glutamate dehydrogenase, the amount of tritium found in the gluta...
متن کاملThe Mechanism of Aconitase Action
When a number of metal ions were tested as activators over a lOO-fold range of metal ion concentration (0.01 to 1.0 mM), aconitase was specifically activated by Fe(II). Manganese(I1) does not activate aconitase but binds to the enzyme, as shown indirectly by inhibition of the enzyme activation by Fe(I1) and directly by electron paramagnetic resonance. A titration of the enzyme with Mn(I1) may b...

متن کاملMechanism of Action of the Thyroid Hormone on the Heart
SUMMARY The foliowing cardiac effects may be attributed to thyroxin: 1-Thyroxin augments all anaerobic processes in the body includ::ng the heart, and decreases the glycogen content of the heart ( 1, 2, 5, 27). The resistance of the heart to anoxia is increased in hyperthyroidism ( 25). 2- Thyroxin influences the cardiac weight and prevents cardiac atrophy (3, 8, 10, 11, 19, 20, 21, 30...
متن کاملAntibacterial Activity of Polypyrrole-Chitosan Nanocomposite: Mechanism of Action
Polypyrrole-chitosan nanocomposite (PPy-CTN) was synthesized by dispersion polymerization of PPy in presence of CTN. Preparation of spherical PPy nanoparticles that were successfully covered with a thin layer of chitosan was confirm by transmission electron microscopy (TEM) technique. Characterization techniques also revealed the presence of CNT in the polymer matrix and its presence was confir...
