Statins’ structure blocks cholesterol

Cholesterol-clobbering drugs called statins do their good work via the molecular equivalent of a sit-down strike, report researchers in the May 11 Science. The researchers used X-ray crystallography to determine the detailed structure of six different types of statins. From these, they deduced that the proteins interrupt a cascade of cholesterol-building events by physically blocking the binding site of an enzyme called HMGR.
