== Publication Abstract from PubMed ==
Plants produce a wide variety of secondary metabolites in response to adverse environmental factors. Z,Z-Farnesyl diphosphate (Z,Z-FPP), synthesized by Z,Z-farnesyl diphosphate synthase (zFPS), supports the formation of phytochemicals in wild tomatoes. Here, the crystal structure of N-terminal truncated zFPS (DeltazFPS) was determined. Irregular products including lavandulyl diphosphate and an unknown compound were surprisingly found. Apart from the truncated N-terminus as a functional regulator, structure-based analysis and mutagenesis assays revealed a residue H103 in DeltazFPS as one of the key elements to this irregular function. A series of substrate-enzyme complex structures were obtained from DeltazFPS-H103Y by co-crystallizing with isopentenyl diphosphate, dimethylallyl thiolodiphosphate, or both. Various substrate-binding modes were revealed. The catalytic mechanisms of both the head-to-tail and head-to-middle reactions in DeltazFPS were proposed. Functional switch between the two mechanisms in this enzyme and the essential role played by the flexible C-terminus were elucidated as well.
