In hepatic microsomes HMG CoA and NADPH inhibit thein vitrodephosphorylation and activation of the enzyme, HMG CoA reductase,in situin the hepatic microsome. This inhibition occurs with both cytosolic phosphatases and potato acid phosphatase, indicating that HMG CoA and NADPH block the dephosphorylation of microsomal HMG CoA reductase through an interaction with HMG CoA reductase and not with the phosphatases. Neither HMG CoA nor NADPH inhibits the dephosphorylation of paranitrophenol phosphate, indicating the selective protection of HMG CoA reductase from dephosphorylation. The inactivation of HMG CoA reductase by Mg++and ATP is not affected by HMG CoA and NADPH, indicating that HMG CoA and NADPH specifically inhibit only the dephosphorylation of HMG CoA reductase and do not affect the phosphorylation of this enzyme.
