Purification of 3-hydroxy-3-methylglutaryl coenzyme A reductase.
The enzyme 3-hydroxy-3-methylglutaryl coenzyme agarose, glucose-6-phosphate dehydrogenase, and aldolA reductase from human liver was purified to homogeneity. ase were from Sigma Chemical co.; agarose-hexaneHMG-CoA was from P-L Biochemicals; bovine serum Electrophoresis of the purified human enzyme on non-denaturing gels revealed a single protein-staining band that co-migrated with reductase act...
متن کاملChrysosporin, a new inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase produced by Chrysosporium pannorum.
Cholesterol is synthesized via more than 20 enzymatic reactions. This pathway is mainly regulated by the enzyme, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA)reductase1}. Recent clinical results have shown that HMG-CoA reductase inhibitors such as lovastatin2) (monacolin K3)) are safe and effective drugs for treatment of hypercholesterolemia4). Wehave previously reported that Chrysosporium pa...
متن کاملPannorin, a new 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor produced by Chrysosporium pannorum.
Pannorin, a naphthopyrone that inhibits 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the rate-limiting enzyme in cholesterol synthesis, was isolated from a culture broth of Chrysosporium pannorum M10539 by solvent extraction, Bio-Gel P-6 column chromatography and reverse phase HPLC (Silica ODS). Spectroscopic analyses of the compound yielded 4,8,10-trihydroxy-5-methyl-2H-naphtho[1...
متن کاملDefective regulation of 3-hydroxy-3-methylglutaryl coenzyme A reductase in a somatic cell mutant.
A somatic cell mutant of the CHO-K1 cell selected to be resistant to the killing effects of 25-hydroxycholesterol in the absence of cholesterol is shown to be defective in the inhibition of 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase activity by 25-hydroxycholesterol, cholesterol, and lipoproteins, thus maintaining the enzyme activity found in cells in the absence of exogenous sterol con...
متن کاملPleiotropic effects of 3-hydroxy-3-methylglutaryl coenzyme a reductase inhibitors.
The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors or statins are potent inhibitors of cholesterol biosynthesis. Several large clinical trials have demonstrated the beneficial effects of statins in the primary and secondary prevention of coronary heart disease. However, the overall clinical benefits observed with statin therapy appear to be greater than what might be expected from c...
