Abstract
Isoryanodane and ryanodane diterpenes have a carbon skeleton correlation in structures, and their natural product-oxidized diterpenes show antifeedant and insecticidal activities against Hemiptera and Lepidoptera. While ryanodine mainly acts on the ryanodine receptor (RyR), isoryanodane does not. In this study, we demonstrated that itol A, an isoryanodane diterpenoid, could significantly downregulate the expression level of juvenile hormone-binding protein (JHBP), which plays a vital role in JH transport. RNAi bioassay indicated that silencing the Spodoptera frugipreda JHBP (SfJHBP) gene decreased itol A activity, which confirmed the developmental phenotypic observation. Parallel reaction monitoring (PRM) further confirmed that itol A affected JHBP's expression abundance. Although JHBP is not proven as the direct or only target of itol A, we confirmed that itol A's action effect depends largely on JHBP and that JHBP is a potential target of itol A. We present foundational evidence that itol A inhibits the growth and development of Spodoptera frugiperda mainly through hijacking JHBP.

Abstract
Juvenile hormones (JHs) regulate important processes in insects, such as postembryonic development and reproduction. In the hemolymph of Lepidoptera, these lipophilic sesquiterpenic hormones are transported from their site of synthesis to target tissues by high affinity carriers, the juvenile hormone binding proteins (JHBPs). Lepidopteran JHBPs belong to a recently uncovered, yet very ancient family of proteins sharing a common lipid fold (TULIP domain) and involved in shuttling various lipid ligands. One important, but poorly understood aspect of JHs action, is the mechanism of hormone transfer to or through the plasma membranes of target cells. Since many membrane-active peptides and proteins, such as the pore-forming bacterial toxins, are activated by low pH or interaction with phospholipid membranes, we have examined the effect of these factors on JH binding by JHBPs. The affinity of Bombyx mori and Manduca sexta JHBPs for JH III was determined by the DCC assay, equilibrium dialysis, and isothermal titration calorimetry, and found to be greatly reduced at low pH, in agreement with previous observations. Loss of binding was accompanied by changes in fluorescence and near-UV CD spectra, indicating significant changes in protein structure in the environment of aromatic residues. The apparent dissociation rate constant (koff) of the JHBP-JH III complex was greater at acidic pH, suggesting that low pH favors ligand release by opening of the binding pocket. The affinity of recombinant B. mori JHBP (rBmJHBP) was also decreased in the presence of anionic phospholipid vesicles. Measurements of steady-state fluorescence anisotropy with the lipophilic probe TMA-DPH demonstrated that rBmJHBP specifically interacts with anionic membranes. These results suggest the existence of a collisional mechanism for ligand release that may be important for delivery of JHs to the target cells, and could be relevant to the function of related members of this emerging family of lipid-transport proteins.

Abstract
A novel approach in the analysis of difference-UV spectrophotometric data for determining the heat denaturation degree of bovine serum albumin (BSA) was assessed. Five different parameters of difference-UV spectra were obtained by subtracting spectra of unheated and denatured protein solutions at different temperature-time combinations. BSA was found to exhibit a maximum degree of heat denaturation of about 17% compared to the complete unfolding caused by 6M guanidine hydrochloride. This low degree of heat denaturation is probably caused by the aggregation of the initially unfolded protein molecules. The kinetic analysis exhibited discontinuities in the Arrhenius plots, distinguishing the unfolding and aggregation phases of the denaturation process, whereas such a discrimination could not be obtained by differential scanning calorimetry analyses. The proposed method is accurate, fast, simple and sensitive enough to detect changes in the protein heat denaturation even at short temperature-time intervals.

Abstract
Juvenile hormone binding protein (JHBP) is the key element of the system that transmits hormone signals to target tissues. Recently, we found that the core promoter of the jhbp gene is strongly under the control of the TATA box and the transcription start site. In this report, we have shown that the jhbp promoter contains distal regulatory elements whose functionality clearly depends on the particular cell environment and that the scope of research from one cell line is insufficient to generalize the conclusions of the analysis. Cf1/Usp (where Usp is ultraspiracle protein previously known as Cf1, chorion factor 1) elements suppressed transcription of the reporter gene in the High Five cell line but not in the Sf9 cell line. However, upstream from all three Cf1/Usp elements there is a DNA sequence, containing the Zeste element, which activates jhbp in both systems. We found that juvenile hormone strongly inhibited the activity of the jhbp promoter in the Sf9 cell line, whereas it did not have an effect in the High Five cell line. A second key hormone that controls insect development--20-hydroxyecdysone, was also found to suppress the transcription of jhbp. This is the first report describing how these two hormones affect jhbp gene expression in different cell lines.

Abstract
Juvenile hormones (JHs) control a diversity of crucial life events in insects. In Lepidoptera which major agricultural pests belong to, JH signaling is critically controlled by a species-specific high-affinity, low molecular weight JH-binding protein (JHBP) in hemolymph, which transports JH from the site of its synthesis to target tissues. Hence, JHBP is expected to be an excellent target for the development of novel specific insect growth regulators (IGRs) and insecticides. A better understanding of the structural biology of JHBP should pave the way for the structure-based drug design of such compounds. Here, we report the crystal structure of the silkworm Bombyx mori JHBP in complex with two molecules of 2-methyl-2,4-pentanediol (MPD), one molecule (MPD1) bound in the JH-binding pocket while the other (MPD2) in a second cavity. Detailed comparison with the apo-JHBP and JHBP-JH II complex structures previously reported by us led to a number of intriguing findings. First, the JH-binding pocket changes its size in a ligand-dependent manner due to flexibility of the gate α1 helix. Second, MPD1 mimics interactions of the epoxide moiety of JH previously observed in the JHBP-JH complex, and MPD can compete with JH in binding to the JH-binding pocket. We also confirmed that methoprene, which has an MPD-like structure, inhibits the complex formation between JHBP and JH while the unepoxydated JH III (methyl farnesoate) does not. These findings may open the door to the development of novel IGRs targeted against JHBP. Third, binding of MPD to the second cavity of JHBP induces significant conformational changes accompanied with a cavity expansion. This finding, together with MPD2-JHBP interaction mechanism identified in the JHBP-MPD complex, should provide important guidance in the search for the natural ligand of the second cavity.

Abstract
Juvabione, dehydrojuvabione and their aromatic analogues act as juvenile hormone mimics against diverse strains of insect species. Large numbers of modified juvenoids containing the juvabione skeleton, with various structural variations, are synthesized. Some of these compounds exhibit a very high degree of juvenile hormone activity and are presently in use. In this paper we report a comparative molecular docking study of synthesized juvabione, natural juvenile hormone III and synthetic insect growth regulators (fenoxycarb, S-21149, Compound 1, pyriproxyfen) with the juvenile hormone binding protein of Galleria mellonella. The study clearly indicates a higher binding affinity of nitro-substituted juvabione over natural juvenile hormone III and synthetic insect growth regulators such as fenoxycarb and S-21149.

Abstract
In this work, we report a synthetic approach to a Fmoc-protected nucleoamino acid, based on L-diaminopropanoic acid, carrying the DNA nucleobase on the alpha-amino group by means of an amide bond, suitable for the solid-phase synthesis of novel nucleopeptides of potential interest in biomedicine. After ESI-MS and NMR characterization this building block was used for the assembly of a thymine-functionalized nucleopeptide, composed of nucleobase-containing L-diaminopropanoic acid moieties and underivatized L-lysine residues alternated in the backbone. Circular dichroism studies performed on the cationic nucleopeptide and adenine-containing DNA and RNA molecules suggested that the thymine-containing peptide is able to interact with both DNA and RNA. In particular, a significant conformational variation in the RNA structure was suggested by CD studies. Human serum stability assays were also conducted on the cationic nucleopeptide, which was found to be highly resistant to enzymatic degradation.

Abstract
This work deals with the Dakin-West synthesis, starting from the nucleoamino acid 1-thyminyl acetic acid, as well the NMR, ESI MS, and X-ray characterization of a heteroaromatic compound denominated by us T(2)CO, comprising two thymine moieties anchored to a 2-propanonic unit, the spectroscopic properties of which were studied by UV as a function of temperature and ionic strength. Preliminary binding-studies with molecules of biomedical interest such as nucleic acids and proteins, performed on samples containing T(2)CO, suggested that this molecule is able to interact very weakly with double-stranded RNA, whereas it does not seem to bind other nucleic acids or proteins. Moreover, by studies with fresh human serum we found that T(2)CO is resistant to enzymatic degradation till 24 h, whereas UV metal binding-studies, performed using solutions of copper (II) chloride dihydrate and nickel (II) chloride hexahydrate, revealed a certain ability of T(2)CO to bind copper (II) cation. Finally, by CD spectroscopy we investigated the influence of T(2)CO on the already described supramolecular networks based on L-serine-containing nucleopeptides. More particularly, we found that T(2)CO is able to increase the level of structuration of the non-covalent supramolecular assembly of the chiral nucleopeptides, which is a feature of remarkable interest for the development of innovative drug delivery tools.

Abstract
Juvenile hormone binding protein (JHBP) acts as a shuttle, carrying one of the most crucial hormones for insect development to target tissues. We have found that although the JHBP molecule does not contain tryptophan residues, it exhibits a weak fluorescence maximum near 420nm upon excitation at 315nm. Gel filtration experiments performed in denaturing conditions and ESI-MS analyses excluded the possibility that some low molecular ligand was bound to the protein molecules. Further UV and CD spectroscopy studies, as well as immunoblotting, showed that the unusual JHBP optical properties were due to dityrosine intramolecular cross-linking. These bridges were detected both in native and recombinant protein molecules. We believe that in Galleria mellonella hemolymph the DT generation occurs via ROS-mediated oxidation leading to the formation of cross-linked JHBP monomers. MS analyses of peptides generated after JHBP proteolysis indicated, that the dityrosine bridge occurs between the Y128 and Y130 residues.

Abstract
A novel cationic peptide based on L-lysine and L-diaminobutyric acid was prepared for the first time by solid phase synthesis. After HPLC purification and ESI MS characterization, we studied by CD and IR spectroscopy the structural features of the novel basic peptide, which is able to form a β-turn-like structure. Furthermore, its interaction with DNA and RNA was investigated by CD and UV spectroscopy, which revealed a preferential RNA-binding ability of the sequential peptide, whereas its inhibitory activity toward HIV and Moloney murine leukemia virus (MMLV) reverse transcriptase action was evaluated by semiquantitative PCR. The cationic sequential peptide was able to inhibit the reverse transcriptase activity in both cases, even if our PCR data suggested a major activity in the case of HIV-RT, probably due to the stronger cationic peptide-protein interaction evidenced by UV spectroscopy.

Abstract
Juvenile hormone (JH) regulates insect growth and development. JH present in the hemolymph is bound to juvenile hormone binding protein (hJHBP) which protects JH from degradation. In G. mellonella, this protein is glycosylated only at one (Asn(94)) of the two potential N-linked glycosylation sites (Asn(4) and Asn(94)). To investigate the function of glycosylation, each of the two potential glycosylation sites in the rJHBP molecule was examined by site-directed mutagenesis. MS analysis revealed that rJHBP overexpressed in the P. pastoris system may appear in a non-glycosylated as well as in a glycosylated form at both sites. We found that mutation at position Asn(94) reduces the level of protein secretion whereas mutation at the Asn(4) site has no effect on protein secretion. Purified rJHBP and its mutated forms (N4W and N94A) have the same JH binding activities similar to that of hJHBP. However, both mutants devoid of the carbohydrate chain are more susceptible to thermal inactivation. It is concluded that glycosylation of JHBP molecule is important for its thermal stability and secretion although it is not required for JH binding activity.

Abstract
In this work, we report the synthesis of a novel Fmoc-protected nucleoaminoacid, based on 4-piperidinyl glycine, carrying the DNA nucleobase on the secondary amino group, suitable for the solid-phase synthesis of nucleopeptides. After ESI-MS and NMR characterization this building block was used for the assembly of a thymine-functionalized tetrapeptide, composed of 4-piperidinyl glycine and L-arginine moieties alternated in the backbone. The ability to interact with RNA and the efficiency in interfering with the reverse transcription of eukaryotic mRNA of the novel nucleo-tetrapeptide found in this study are in favour of the employment of chiral nucleopeptides based on alternate 4-piperidinyl glycine/L-arginine backbone in biomedicine.

Abstract
Low molecular weight juvenile hormone binding proteins (JHBPs) are specific carriers of juvenile hormone (JH) in the hemolymph of butterflies and moths. As hormonal signal transmitters, these proteins exert a profound effect on insect development. The crystal structure of JHBP from Galleria mellonella shows an unusual fold consisting of a long alpha-helix wrapped in a highly curved antiparallel beta-sheet. JHBP structurally resembles the folding pattern found in tandem repeats in some mammalian lipid-binding proteins, with similar organization of one cavity and a disulfide bond between the long helix and the beta-sheet. JHBP reveals, therefore, an archetypal fold used by nature for hydrophobic ligand binding. The JHBP molecule possesses two hydrophobic cavities. Several lines of experimental evidence conclusively indicate that JHBP binds JH in only one cavity, close to the N- and C-termini, and that this binding induces a structural change. The second cavity, located at the opposite end of the molecule, could bind another ligand.

Abstract
We have used UV difference spectroscopy and fluorescence spectroscopy to study the perturbation by beta-cyclodextrin of tyrosyl or tryptophyl residues located at each of the 10 variable consensus contact positions in the third domain of turkey ovomucoid. The goal was to monitor the accessibility of the side chain rings of these residues when located at these positions. The results indicated that the tyrosyl or tryptophyl rings are most highly exposed when located in the P1 position followed by the P4 position. It was possible to determine the association constants for beta-cyclodextrin binding at these positions. When located at the P2, P5, P6 and P3' positions, the rings of the tyrosyl or tryptophyl residues were exposed but less so than at the P1 or P4 positions. By contrast, when located at the P1', P2', P14' and P18' positions, the tyrosyl or tryptophyl residues were insufficiently exposed to be perturbed by beta-cyclodextrin, although they reacted positively to dimethyl sulfoxide solvent perturbation. These findings indicate that beta-cyclodextrin perturbation provides a convenient way to detect highly exposed tyrosyls or tryptophyls in proteins. Furthermore, we evaluated the ability of beta-cyclodextrin to inhibit the interaction of turkey ovomucoid third domain variants with different P1 residues. The results showed that the presence of beta-cyclodextrin had little effect on the association constant when the P1 residue was a glycyl residue, but greatly decreased the association constant when the P1 residue was a tyrosyl or tryptophyl residue. Thus, beta-cyclodextrin may be used to selectively modulate the interaction between proteinase inhibitors and their cognate enzymes.

Abstract
Juvenile hormone (JH) regulates insect development. JH present in the hemolymph is bound to a specific glycoprotein, juvenile hormone binding protein (JHBP), which serves as a carrier to deploy the hormone to target tissues. In this report structural changes of JHBP from Galleria mellonella induced by guanidine hydrochloride have been investigated by a combination of size-exclusion chromatography, protein activity measurements, and spectroscopic methods. Molecules of JHBP change their conformation from a native state via two unstable intermediates to a denatured state. The first intermediate appears in a compact state, because it slightly changes its molecular size and preserves most of the JHBP secondary structure of the native state. Although the second intermediate also preserves a substantial part of the secondary structure, it undergoes a change into a noncompact state changing its Stokes radius from approximately 30 to 39 A. Refolding experiments showed that JHBP molecules recover their full protein structure, as judged from the CD spectrum, fluorescence experiments, and JH binding activity measurements. The free energy of unfolding in the absence of the denaturant, DeltaG(D-N), is calculated to be 4.1 kcal mol(-1).

Abstract
The juvenile hormone binding protein (JHBP) from Galleria mellonella hemolymph is a glycoprotein composed of 225 amino acid residues. It contains four Cys residues forming two disulfide bridges. In this study, the topography of the disulfide bonds as well as the site of glycan attachment in the JHBP molecule from G. mellonella was determined, using electrospray mass spectrometry. The MS analysis was performed on tryptic digests of JHBP. Our results show that the disulfide bridges link Cys10 and Cys17, and Cys151 and Cys195. Of the two potential N-glycosylation sites in JHBP, Asn4, and Asn94, only Asn94 is glycosylated. This site of glycosylation is also found in the fully biologically active recombinant JHBP expressed in the yeast Pichia pastoris.

Abstract
Galleria mellonella juvenile hormone binding protein (JHBP) is a single chain glycoprotein with two disulfide bonds and a molecular mass of 25,880 Da. This report describes the expression of JHBP in bacteria and yeast cells (Pichia pastoris). The expression in bacteria was low and the protein was rapidly degraded upon cell lysis. The expression of His8-tagged rJHBP (His8-rJHBP) in P. pastoris was high and the non-degraded protein was purified to homogeneity with high yield in a one-step immobilized Ni++ affinity chromatography. His8-rJHBP from P. pastoris contains one JH III binding site with KD of 3.7 +/- 1.3x10(-7) M. The results suggest that P. pastoris is the preferred system for expression of His8-rJHBP in non-degraded fully active form.

Abstract
Juvenile hormone binding proteins (JHBPs) serve as specific carriers of juvenile hormone (JH) in insect hemolymph. As shown in this report, Galleria mellonella JHBP is encoded by a cDNA of 1063 nucleotides. The pre-protein consists of 245 amino acids with a 20 amino acid leader sequence. The concentration of the JHBP mRNA reaches a maximum on the third day of the last larval instar, and decreases five-fold towards pupation. Comparison of amino acid sequences of JHBPs from Bombyx mori, Heliothis virescens, Manduca sexta and G. mellonella shows that 57 positions out of 226 are occupied by identical amino acids. A phylogeny tree was constructed from 32 proteins, which function could be associated to JH. It has three major branches: (i) ligand binding domains of nuclear receptors, (ii) JHBPs and JH esterases (JHEs), and (iii) hypothetical proteins found in Drosophila melanogaster genome. Despite the close positioning of JHEs and JHBPs on the tree, which probably arises from the presence of a common JH binding motif, these proteins are unlikely to belong to the same family. Detailed analysis of the secondary structure modeling shows that JHBPs may contain a beta-barrel motif flanked by alpha-helices and thus be evolutionary related to the same superfamily as calycins.

Abstract
It has been previously suggested that juvenile hormone binding protein(s) (JHBP) belongs to a new class of proteins. In the search for other protein(s) that may contain structural motifs similar to those found in JHBP, hemolymph from Galleria mellonella (Lepidoptera) was chromatographed over a Sephadex G-200 column and resulting fractions were subjected to SDS-PAGE, transferred onto nitrocellulose membrane and scanned with a monoclonal antibody, mAb 104, against hemolymph JHBP. Two proteins yielded a positive reaction with mAb 104, one corresponding to JHBP and the second corresponding to a transferrin, as judged from N-terminal amino acid sequencing staining. Transferrin was purified to about 80% homogeneity using a two-step procedure including Sephadex G-200 gel filtration and HPLC MonoQ column chromatography. Panning of a random peptide display library and analysis with immobilized synthetic peptides were applied for finding a common epitope present in JHBP and the transferrin molecule. The postulated epitope motif recognized by mAb 104 in the JHBP sequence is RDTKAVN, and is localized at position 82-88.
