The relaxed complex scheme, a virtual-screening methodology that accounts for protein receptor flexibility, was used to identify a low-micromolar, non-bisphosphonate inhibitor of farnesyl diphosphate synthase. Serendipitously, we also found that several predicted farnesyl diphosphate synthase inhibitors were low-micromolar inhibitors of undecaprenyl diphosphate synthase. These results are of in...

in view of the importance of terpene in human’s life, analyzing the relationship between them and the involved genes are of crucial necessity. the necessity is for exploring influential genes. among different plants containing terpene, artemisia is included. in this study, several genes farnesyl diphosphate synthase (fds), hydroxy-2-methyl-2-(e)-butenyl 4-diphosphate reductase (hdr) and isopent...

The first step in the conversion of the isoprenoid intermediate, farnesyl diphosphate (FDP), to sesquiterpene phytoalexins in cotton (Gossypium barbadense) plants is catalyzed by delta-cadinene (CDN) synthase. CDN is the precursor of desoxyhemigossypol and hemigossypol defense sesquiterpenes. In this paper we have studied the mechanism for the cyclization of FDP and the putative intermediate, n...

Like seed plants, liverworts synthesize and accumulate a myriad of isoprenoid compounds. Using antibodies raised against several isoprenoid biosynthetic enzymes, we investigated their intracellular compartmentation by in situ immunolocalization from Marchantia polymorpha. The enzymes examined were deoxy-xylulose phosphate synthase, geranyl diphosphate synthase, farnesyl diphosphate synthase, ge...

Aphids are important insect pests in temperate regions, damaging crop plants by sucking nutrients from the phloem and by transmitting plant viruses [1]. Chemical control of certain aphid species is becoming extremely difficult due to resistance to insecticides [2]. In this context, the development of novel pest control products that specifically target aphids is highly desirable. To this end, w...
