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 کامل3-Hydroxy-3-methylglutaryl coenzyme A reductase activity in the human gastrointestinal tract.
Activity of 3-hydroxy-3-methylglutaryl coenzyme A reductase (EC 1.1.1.34) was measured in intestinal mucosa of the human gastrointestinal tract. Activity was highest in gastric mucosa (18.2 pmol per mg per min) and there was a constant low level in the small bowel and colon (approximately 10 pmol per mg per min). Phosphorylation/dephosphorylation modulation of intestinal reductase activity was ...
متن کاملCircadian variation of 3-hydroxy-3-methylglutaryl coenzyme A reductase activity in swine liver and ileum.
The temporal variation of HMG-CoA reductase activity in the liver and intestine of swine was investigated. The thin-layer chromatographic method widely used in the assay of the reductase was successfully applied to the porcine enzymes. Parallel circadian rhythms were demonstrated in both hepatic and ileal reductases from mash-fed animals. Peak activity occurred approximately 6 hr after feeding,...
متن کاملRegulation of 3-hydroxy-3-methylglutaryl coenzyme-A reductase activity in type II hyperlipoproteinaemia.
The regulation of 3-hydroxy-3-methylglutaryl coenzyme-A reductase activity in leucocytes was studied in a family with familial type II hyperlipoproteinaemia (WHO classification). The propositus was heterozygous and 16 other members of the family were studied. Leucocytes were isolated by a relatively quick and simple procedure and used for enzyme estimations. The results suggest that measurement...
متن کاملHepatic cholesterol metabolism in obesity: activity of microsomal 3-hydroxy-3-methylglutaryl coenzyme A reductase.
Obesity is often associated with an elevated total body cholesterol synthesis. In order to evaluate the role of hepatic cholesterogenesis in this phenomenon, we assayed the rate-limiting step in cholesterol biosynthesis, 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase in the microsomal fraction of liver biopsies obtained operatively from ten morbidly obese (relative body weight greate...
