Characteristics of rat liver microsomal 3-hydroxy-3-methylglutaryl-coenzyme A reductase
Abstract
A procedure for the preparation of rat liver microsomal fractions essentially devoid of contaminating lysosomes is described. When this preparation was examined by immunoblotting with a rabbit antiserum to rat 3-hydroxy-3-methylglutaryl-CoA reductase, a single band corresponding to an Mr of 100000 was observed. No evidence was found for glycosylation of rat liver-3-hydroxy-3-methylglutaryl-CoA reductase. Native rat liver microsomal 3-hydroxy-3-methylglutaryl-CoA reductase differs from the purified proteolytically modified species in that it displays allosteric kinetics towards NADPH.
