Epub 2013 Jul 24. Smith, Paul F. (University of South Dakota, Vermillion), and C. V. Henrikson. Two of the most important discoveries in isoprenoid biosynthetic studies in recent years are the elucidation of a second isoprenoid biosynthetic pathway [the methylerythritol phosphate (MEP) pathway] and a modified mevalonic acid (MVA) pathway.
