Lipitor (atorvastatin) is a statin medication that inhibits the enzyme HMG-CoA reductase, a key enzyme in the mevalonate pathway. The binding site of Lipitor on HMG-CoA reductase is a critical aspect of its mechanism of action.

Studies have identified the binding site of Lipitor on HMG-CoA reductase as the active site, which is located in the substrate-binding pocket of the enzyme [1]. The active site is a hydrophobic pocket that is lined with non-polar residues, making it an ideal binding site for Lipitor [2].

The binding site of Lipitor on HMG-CoA reductase has been mapped using X-ray crystallography and molecular dynamics simulations [3]. The results show that Lipitor binds to the active site of HMG-CoA reductase through hydrogen bonding and π-π stacking interactions with the enzyme's residues [4].

The binding site of Lipitor on HMG-CoA reductase is highly specific, with the drug binding to a specific conformation of the enzyme [5]. This specificity is critical for the efficacy and safety of Lipitor, as it allows the drug to selectively inhibit HMG-CoA reductase while minimizing off-target effects [6].

In summary, the binding site of Lipitor on HMG-CoA reductase is the active site, a hydrophobic pocket lined with non-polar residues. The binding site is highly specific, allowing Lipitor to selectively inhibit HMG-CoA reductase while minimizing off-target effects.
