Rat hepatic 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase was purified to homogeneity using agarose-HMG-CoA affinity chromatography. Additional protein was isolated from the affinity column with 0.5 M KCl that demonstrated no HMG-CoA reductase activity, yet comigrated with purified HMG-CoA reductase on sodium dodecyl sulfate-polyacrylamide gels. This protein was determined to be an inactive form of HMG-CoA reductase by tryptic peptide mapping, reaction with anti-HMG-CoA reductase antibody, and coelution with purified HMG-CoA reductase from a molecular-sieving high-performance liquid chromatography column. This inactive protein was present in at least fourfold greater concentration than active HMG-CoA reductase, and could not be activated by rat liver cytosolic phosphoprotein phosphatases. Immunotitration studies with microsomal and solubilized HMG-CoA reductase isolated in the presence and absence of proteinase inhibitors suggested that the inactive protein was not generated from active enzyme during isolation of microsomes or freeze-thaw solubilization of HMG CoA reductase.
