Imp dehydrogenase activity
Inosine-5′-monophosphate dehydrogenase (IMPDH) is a purine biosynthetic enzyme that catalyzes the nicotinamide adenine dinucleotide (NAD )-dependent oxidation of inosine monophosphate (IMP) to xanthosine monophosphate (XMP), the first committed and rate-limiting step towards the de novo … Zobacz więcej IMPDH is a tetrameric enzyme, composed of monomeric subunits with molecular masses of approximately 55 kDa and generally consist of 400-500 residues.

WitrynaActivity of IMP-dehydrogenase was studied in the cells of P. guilliermondii ATCC 9058 from different growth phase; the yeast was cultivated in iron-rich and iron-deficient media. The highest activity of the enzyme was found in the iron-rich cells from the logarithmic growth phase. In the iron-defici … WitrynaTherefore, we examined the activity of IMP dehydrogenase, the rate-limiting enzyme for GTP biosynthesis, and GMP reductase which counteracts the effect of the synthetic enzyme. Treatment with RA for 48 hours increased GMP reductase activity by 240.9 +/- 24.2% and decreased IMP dehydrogenase activity to 67.5 +/- 8.8% of control values.
WitrynaIn enzymology, a methanol dehydrogenase (MDH) is an enzyme that catalyzes the chemical reaction: . CH 3 OH CH 2 O + 2 electrons + 2H +. How the electrons are captured and transported depends upon the kind of methanol dehydrogenase. There are three main types of MDHs: NAD +-dependent MDH, pyrrolo-quinoline quinone … WitrynaIMP dehydrogenase 2 is the rate-limiting enzyme in the de novo guanine nucleotide biosynthesis. It is thus involved in maintaining cellular guanine deoxy- and ribonucleotide pools needed for DNA and RNA synthesis. IMPDH2 catalyzes the NAD-dependent oxidation of inosine-5'-monophosphate into xanthine-5'-monophosphate, which is then …
