X-RAY STRUCTURE OF TERNARY-SECOISOLARICIRESINOL DEHYDROGENASE
Overview
(-)-Matairesinol is a central biosynthetic intermediate to numerous, 8-8'-lignans, including the antiviral agent podophyllotoxin in Podophyllum, species and its semi-synthetic anticancer derivatives teniposide, etoposide, and Etopophos. It is formed by action of an enantiospecific, secoisolariciresinol dehydrogenase, an NAD(H)-dependent oxidoreductase, that catalyzes the conversion of (-)-secoisolariciresinol. Matairesinol is, also a plant-derived precursor of the cancer-preventative "mammalian", lignan or "phytoestrogen" enterolactone, formed in the gut following, ingestion of high fiber dietary foodstuffs, for example. Additionally, secoisolariciresinol dehydrogenase is involved in pathways to important, plant defense molecules, such as plicatic acid in the western red cedar, (Thuja ... [(full description)]
