STRUCTURE OF POTATO (SOLANUM TUBEROSUM) EPOXIDE HYDROLASE I (STEH1)
Overview
Epoxide hydrolases catalyze the conversion of epoxides to diols. The known, functions of such enzymes include detoxification of xenobiotics, drug, metabolism, synthesis of signaling compounds, and intermediary metabolism., In plants, epoxide hydrolases are thought to participate in general, defense systems. In the present study, we report the first structure of a, plant epoxide hydrolase, one of the four homologous enzymes found in, potato. The structure was solved by molecular replacement and refined to a, resolution of 1.95 A. Analysis of the structure allows a better, understanding of the observed substrate specificities and activity., Further, comparisons with mammalian and fungal epoxide hydrolase, structures reported earlier show the basis of differing substrate, specificities in the various epoxide hydrolase subfamilies. Most plant, enzymes, like the potato epoxide hydrolase, are expected to be monomers, with a preference for substrates with long lipid-like substituents of the, epoxide ring. The significance of these results in the context of, biological roles and industrial applications is discussed.
