Scientists reveal structural secrets of enzyme used to make popular anti-cholesterol drug
In pharmaceutical production, identifying enzyme catalysts that help improve the speed and efficiency of the process can be a major boon. Figuring out exactly why a particular enzyme works so well is an altogether different quest.
Take the cholesterol-lowering drug simvastatin. First marketed commercially as Zocor, the statin drug has generated billions of dollars in annual sales. In 2011, UCLA scientists and colleagues discovered that a mutated enzyme could help produce the much sought-after pharmaceutical far more efficiently than the chemical process that had been used for years — and could do it better than the natural, non-mutated version of the enzyme. But no one quite knew why, until another team of UCLA researchers cracked the mystery. (more…)
