SQUALENE-HOPENE CYCLASE
OverviewOverview
The binding structures of 11 human oxidosqualene cyclase inhibitors, designed as cholesterol-lowering agents were determined for the, squalene-hopene cyclase from Alicyclobacillus acidocaldarius, which is the, only structurally known homologue of the human enzyme. The complexes were, produced by cocrystallization, and the structures were elucidated by X-ray, diffraction analyses. All inhibitors were bound in the large active center, cavity. The detailed binding structures are presented and discussed in the, light of the IC50 values of these 11 as well as 17 other inhibitors. They, provide a consistent picture for the inhibition of the bacterial enzyme, and can be used to adjust and improve homology models of the human enzyme., The detailed active center structures of the two enzymes are too different, to show an IC50 correlation.
