Catalysis of NO production by a molybdoenzyme model.

چکیده
[reaction--see text] Nitric oxide (NO) is an important biological messenger molecule. Nitrates, including nitroglycerin (GTN), are clinically important vasodilators believed to be biotransformed in vivo to NO, a 3e(-) reduction. Molybdenum hydrotris-(3,5-dimethyl-1-pyrazolyl) borate complex (MoTPB) was shown to be an efficient catalyst of GTN degradation, with triphenylphosphine (Ph(3)P) acting as reducing cofactor, producing significant amounts of NO. MoTPB/Ph(3)P is an excellent enzyme model system, showing the feasibility of nitrate biotransformation mediated by a molybdoenzyme.

متن کاملTheoretical analysis of biochemical pathways of nitric oxide release from vascular endothelial cells.
Vascular endothelium expressing endothelial nitric oxide synthase (eNOS) produces nitric oxide (NO), which has a number of important physiological functions in the microvasculature. The rate of NO production by the endothelium is a critical determinant of NO distribution in the vascular wall. We have analyzed the biochemical pathways of NO synthesis and formulated a model to estimate NO product...

In the present research, the selective oxidation of lauryl alcohol to lauraldehyde was studied under liquid-liquid phase transfer conditions using potassium chromate (K2CrO4) as an oxidizing agent and tetrabutyl ammonium bromide (TBAB) as the phase transfer catalyst. Chromium (VI) reagents are used in these oxidations since the alcohols are selectively oxidized <e...
متن کاملThe Mo-Se active site of nicotinate dehydrogenase.
Nicotinate dehydrogenase (NDH) from Eubacterium barkeri is a molybdoenzyme catalyzing the hydroxylation of nicotinate to 6-hydroxynicotinate. Reactivity of NDH critically depends on the presence of labile (nonselenocysteine) selenium with an as-yet-unidentified form and function. We have determined the crystal structure of NDH and analyzed its active site by multiple wavelengths anomalous dispe...
