Abstract
Reducing the use of broad-spectrum insecticides is one of the many challenges currently faced by insect pest management practitioners. For this reason, efforts are being made to develop environmentally benign pest-control products through bio-rational approaches that aim at disrupting physiological processes unique to specific groups of pests. Perturbation of hormonal regulation of insect development and reproduction is one such strategy. It has long been hypothesized that some enzymes in the juvenile hormone biosynthetic pathway of moths, butterflies and caterpillars (order Lepidoptera) display unique structural features that could be targeted for the development of Lepidoptera-specific insecticides, a promising avenue given the numerous agricultural and forest pests belonging to this order. Farnesyl diphosphate synthase, FPPS, is one such enzyme, with recent work suggesting that it has structural characteristics that may enable its selective inhibition. This review synthesizes current knowledge on FPPS and summarizes recent advances in its use as a target for insecticide development.

Abstract
The juvenile hormones (JHs) are a family of insect acyclic sesquiterpenoids produced by the corpora allata (CA), a pair of endocrine glands connected to the brain. They are involved in the regulation of development, reproduction, behavior, caste determination, diapause, stress response, and numerous polyphenisms. In the post-genomics era, comprehensive analyses using functional 'omics' technologies such as transcriptomics, proteomics and metabolomics have increased our understanding of the activity of the minute CA. This review attempts to summarize some of the 'omics' studies that have contributed to further understand JH synthesis in insects, with an emphasis on our own research on the mosquito Aedes aegypti.

Structural characterization of a lepidopteran type-II farnesyl diphosphate synthase from the spruce budworm, Choristoneura fumiferana: Implications for inhibitor design. INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY 2018; 92:84-92. [PMID: 29183817 DOI: 10.1016/j.ibmb.2017.11.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Revised: 11/21/2017] [Accepted: 11/22/2017] [Indexed: 06/07/2023]
Abstract
Farnesyl diphosphate synthase (FPPS) is an enzyme from the class of short chain (E)-prenyltransferases that catalyzes the condensation of two molecules of isopentenyl diphosphate (IPP, C5) with dimethylallyl diphosphate (DMAPP, C5) to generate the C15 product FPP. In insects, FPPS plays a key role in the biosynthesis of the morphogenetic and gonadotropic "juvenile hormone" (JH). Lepidopteran genomes encode two very distinct FPPS paralogs, one of which ("type-II") is expressed almost exclusively in the JH-producing glands, the corpora allata. This paralog has been hypothesized to display structural features that enable the binding of the bulkier precursors required for the biosynthesis of lepidopteran ethyl-branched JHs. Here, we report on the first crystal structures of an insect FPPS solved to date. Apo, ligand-bound, and inhibitor-bound structures of type-II FPPS (FPPS2) from the spruce budworm, Choristoneura fumiferana (Order: Lepidoptera), were obtained. Comparison of apo and inhibitor-bound enzymes revealed differences in both inhibitor binding and structural plasticity of CfFPPS2 compared to other FPPSs. Our data showed that IPP is not essential to the closure of the C-terminal tail. Ortho-substituted pyridinium bisphosphonates, previously shown to inhibit CfFPPS2, bound to the allylic site, as predicted; however, their alkyl groups were oriented towards the homoallylic binding site, with the bulkier propyl-substituted inhibitor penetrating deeply into the IPP binding pocket. The current study sheds light on the structural basis of substrate specificity of type-II FPPS of the spruce budworm. Through a comparison with other inhibitor-bound FPPSs, we propose several approaches to improve inhibitor selectivity and potency.

Abstract
Farnesyl diphosphate synthase (FPPS) catalyzes the condensation of the non-allylic diphosphate, isopentenyl diphosphate (IPP; C5), with the allylic diphosphate primer dimethylallyl diphosphate (DMAPP; C5) to generate the C15 prenyl chain (FPP) used for protein prenylation as well as sterol and terpene biosynthesis. Here, we designed and prepared a series of pyridinium bisphosphonate (PyrBP) compounds, with the aim of selectively inhibiting FPPS of the lepidopteran insect order. FPPSs of Drosophila melanogaster and the spruce budworm, Choristoneura fumiferana, were inhibited by several PyrBPs, and as hypothesized, larger bisphosphonates were more selective for the lepidopteran protein and completely inactive towards dipteran and vertebrate FPPSs. Cell growth of a D. melanogaster cell line was adversely affected by exposure to PyrPBs that were strongly inhibitory to insect FPPS, although their effect was less pronounced than that observed upon exposure to the electron transport disrupter, chlorfenapyr. To assess the impact of PyrBPs on lepidopteran insect growth and development, we performed feeding and topical studies, using the tobacco hornworm, Manduca sexta, as our insect model. The free acid form of a PyrBP and a known bisphosphonate inhibitor of vertebrate FPPS, alendronate, had little to no effect on larval M. sexta; however, the topical application of more lipophilic ester PyrBPs caused decreased growth, incomplete larval molting, cuticle darkening at the site of application, and for those insects that survived, the formation of larval-pupal hybrids. To gain a better understanding of the structural differences that produce selective lepidopteran FPPS inhibition, homology models of C. fumiferana and D. melanogaster FPPS (CfFPPS2, and DmFPPS) were prepared. Docking of substrates and PyrBPs demonstrates that differences at the -3 and -4 positions relative to the first aspartate rich motif (FARM) are important factors in the ability of the lepidopteran enzyme to produce homologous isoprenoid structure and to be selectively inhibited by larger PyrBPs.

Abstract
Our understanding of JH biosynthesis has significantly changed in the last years. In this review I would like to discuss the following topics: (1) the progresses in understanding the JH biosynthesis pathway. Access to genome sequences has facilitated the identification of all the genes encoding biosynthetic enzymes and the completion of comprehensive transcriptional studies, as well as the expression and characterization of recombinant enzymes. Now the existence of different flux directionalites, feed-back loops and pathway branching points in the JH biosynthesis pathways can be explored; (2) the new concepts in the modulation of JH synthesis by allatoregulators. The list of putative JH modulators is increasing. I will discuss their possible role during the different physiological states of the CA; (3) the new theoretical and physiological frameworks for JH synthesis analysis. I will discuss the bases of the flux model for JH biosynthesis. JH plays multiple roles in the control of ovary development in female mosquitoes; therefore, the CA presents different physiological states, where JH synthesis is altered by gating the flux at distinctive points in the pathway; (4) in the final section I will identify new challenges and future directions on JH synthesis research.

Abstract
Isopentenyl diphosphate isomerase (IPPI) of the spruce budworm, Choristoneura fumiferana, and of the tobacco hornworm, Manduca sexta, was cloned and its catalytic properties assessed. In the presence of Mg(2+) or Mn(2+), the recombinant protein from C. fumiferana (CfIPPI) efficiently isomerized IPP to dimethylallyl diphosphate (DMAPP). While C. fumiferana IPPI transcript levels were evenly distributed in a wide variety of tissues, they were highly abundant in the corpora allata. Because IPPI plays an alternate role in lepidopteran juvenile hormone (JH) biosynthesis by catalyzing the isomerization of the homologous substrate, homoisopentenyl diphosphate (HIPP), the ability of CfIPPI to convert HIPP to homodimethylallyl diphosphate (HDMAPP) was also studied. As expected, HIPP isomerization was efficient and the formation of HDMAPP occurred, but the regiospecificity of the reaction was lower than previously found in M. sexta corpora allata homogenates and with purified Bombyx mori IPPI. Differences in inhibitory potency for several alkylated ammonium diphosphates and higher homologs of DMAPP were noted between CfIPPI and a vertebrate IPPI, suggesting that the lepidopteran enzyme has a larger active site cavity. To determine the structural factors responsible for homologous substrate coupling, site directed mutagenesis of several residues identified through sequence alignment and homology modeling analysis was performed. The results suggest that unlike other IPPIs, W216 (C. fumiferana numbering) works in concert with a tyrosine residue (Y105) to allow binding of larger substrates and to stabilize the high-energy intermediate formed during substrate isomerization.

Abstract
Farnesyl diphosphate synthase (FPPS) of the dipteran Drosophila melanogaster has been cloned and its catalytic properties have been assessed. Analysis of the D. melanogaster genome and of ESTs indicates that FPPS is a single copy gene that produces two transcripts, which differ only by 5' extension. The cDNA of shorter and longer D. melanogaster FPPSs (DmFPPS-1a and DmFPPS-1b, respectively) were each subcloned into pET28a and expressed as an N-His6 fusion protein in BL21 E. coli cells. The DmFPPSs similarly catalyzed the coupling of the allylic substrates, GPP and DMAPP, with IPP, producing FPP as product. The longer protein was further characterized. The enzyme required divalent metal for activity, and was activated by 0.1% Triton X-100. Higher detergent concentration and the addition of glycerol, conditions that activate certain insect FPPSs, inhibited prenyl coupling by DmFPPS-1b. Although DmFPPS-1b does not efficiently couple homologous GPP compounds, homodimethylallyl diphosphate (HDMAPP), which is precursor to all homologous JH structures, was a reactive substrate.

Abstract
Two forms of farnesyl diphosphate synthase (FPPS) from the spruce budworm, Choristoneura fumiferana, and one from the armyworm Pseudaletia unipuncta, have been cloned and their catalytic properties assessed. The type-2 FPPS of C. fumiferana (CfFPPS2) was efficient in the prenyl coupling of DMAPP or GPP with [(14)C]IPP, producing FPP as its final product; however, type-1 FPPSs (CfFPPS1, PuFPPS1, as well as Agrotis ipsilon FPPS1) were essentially inactive. A variety of purification methods was employed to purify the type-1 enzymes. Under mild chromatographic conditions, the isolated type-1 enzyme showed modest activity, but was apparently contaminated with endogenous prenyltransferase derived from the Escherichia coli host cells. Similarly, unpurified extracts of PuFPPS1 expressed in an E. coli FPPS-null mutant, had low FPPS activity. When equimolar amounts of homogenous CfFPPS1 and CfFPP2 were combined, a sharp synergistic enhancement of activity was observed, and the coupling of several homologous substrates, which are precursors to ethyl-branched JHs, was enhanced. Association between CfFPPS1 and CfFPPS2 was confirmed by both protein interaction chromatography and competitive ELISA. These data suggest that type-1 and type-2 FPPSs can form a heteromer, which may play a role in sesquiterpene biosynthesis, such as JH homologue formation, in moths.
