Abstract
Isoprenoids are the output of the polymerization of five-carbon, branched isoprenic chains derived from isopentenyl pyrophosphate (IPP) and its isomer, dimethylallyl pyrophosphate (DMAPP). Isoprene units are consecutively condensed to form longer structures such as farnesyl and geranylgeranyl pyrophosphate (FPP and GGPP, respectively), necessary for the biosynthesis of several metabolites. Polyprenyl transferases and synthases use polyprenyl pyrophosphates as their natural substrates; however, it is known that free polyprenols, such as farnesol (FOH), and geranylgeraniol (GGOH) can be incorporated into prenylated proteins, ubiquinone, cholesterol, and dolichols. Furthermore, FOH and GGOH have been shown to block the effects of isoprenoid biosynthesis inhibitors such as fosmidomycin, bisphosphonates, or statins in several organisms. This phenomenon is the consequence of a short pathway, which was observed for the first time more than 25 years ago: the polyprenol salvage pathway, which works via the phosphorylation of FOH and GGOH. Biochemical studies in bacteria, animals, and plants suggest that this pathway can be carried out by two enzymes: a polyprenol kinase and a polyprenyl-phosphate kinase. However, to date, only a few genes have been unequivocally identified to encode these enzymes in photosynthetic organisms. Nevertheless, pieces of evidence for the importance of this pathway abound in studies related to infectious diseases, cancer, dyslipidemias, and nutrition, and to the mitigation of the secondary effects of several drugs. Furthermore, nowadays it is known that both FOH and GGOH can be incorporated via dietary sources that produce various biological effects. This review presents, in a simplified but comprehensive manner, the most important data on the FOH and GGOH salvage pathway, stressing its biomedical importance The main objective of this review is to bring to light the need to discover and characterize the kinases associated with the isoprenoid salvage pathway in animals and pathogens.

Front Chem 2022; 10:1035548. [PMID: 36531309 PMCID: PMC9751614 DOI: 10.3389/fchem.2022.1035548] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Accepted: 11/15/2022] [Indexed: 05/14/2024] Open
Abstract
Plasmodium falciparum is the etiological agent of human malaria, one of the most widespread diseases in tropical and subtropical regions. Drug resistance is one of the biggest problems in controlling the disease, which leads to the need to discover new antimalarial compounds. One of the most promissory drugs purposed is fosmidomycin, an inhibitor of the biosynthesis of isoprene units by the methylerythritol 4-phosphate (MEP) pathway, which in some cases failed in clinical studies. Once formed, isoprene units are condensed to form longer structures such as farnesyl and geranylgeranyl pyrophosphate, which are necessary for Heme O and A formation, ubiquinone, and dolichyl phosphate biosynthesis as well as for protein isoprenylation. Even though the natural substrates of polyprenyl transferases and synthases are polyprenyl pyrophosphates, it was already demonstrated that isoprenoid alcohols (polyprenols) such as farnesol (FOH) and geranylgeraniol (GGOH) can rescue parasites from fosmidomycin. This study better investigated how this rescue phenomenon occurs by performing drug-rescue assays. Similarly, to FOH and GGOH, it was observed that phytol (POH), a 20-carbon plant isoprenoid, as well as unsaponifiable lipid extracts from foods rescue parasites from the antimalarial effect of fosmidomycin. Contrarily, neither dolichols nor nonaprenol rescue parasites from fosmidomycin. Considering this, here we characterized the transport of FOH, GGOH, and POH. Once incorporated, it was observed that these substances are phosphorylated, condensed into longer isoprenoid alcohols, and incorporated into proteins and dolichyl phosphates. Through proteomic and radiolabelling approaches, it was found that prenylated proteins are naturally attached to several isoprenoids, derived from GGOH, dolichol, and POH if exogenously added. Furthermore, the results suggest the presence of at least two promiscuous protein prenyltransferases in the parasite: one enzyme which can use FPP among other unidentified substrates and another enzyme that can use GGPP, phytyl pyrophosphate (PPP), and dolichols, among other substrates not identified here. Thus, further evidence was obtained for dolichols and other isoprenoid products attached to proteins. This study helps to better understand the apicoplast-targeting antimalarial mechanism of action and a novel post-translational modification of proteins in P. falciparum.

Metabolomics profiling reveals new aspects of dolichol biosynthesis in Plasmodium falciparum. Sci Rep 2020; 10:13264.

Abstract
The cis-polyisoprenoid lipids namely polyprenols, dolichols and their derivatives are linear polymers of several isoprene units. In eukaryotes, polyprenols and dolichols are synthesized as a mixture of four or more homologues of different length with one or two predominant species with sizes varying among organisms. Interestingly, co-occurrence of polyprenols and dolichols, i.e. detection of a dolichol along with significant levels of its precursor polyprenol, are unusual in eukaryotic cells. Our metabolomics studies revealed that cis-polyisoprenoids are more diverse in the malaria parasite Plasmodium falciparum than previously postulated as we uncovered active de novo biosynthesis and substantial levels of accumulation of polyprenols and dolichols of 15 to 19 isoprene units. A distinctive polyprenol and dolichol profile both within the intraerythrocytic asexual cycle and between asexual and gametocyte stages was observed suggesting that cis-polyisoprenoid biosynthesis changes throughout parasite’s development. Moreover, we confirmed the presence of an active cis-prenyltransferase (PfCPT) and that dolichol biosynthesis occurs via reduction of the polyprenol to dolichol by an active polyprenol reductase (PfPPRD) in the malaria parasite.

Abstract
Abstract
The reduction pathway leading to the formation of dolichol was clarified in 2010 with the identification of SRD5A3, which is the polyprenol reductase. The finding inspired us to reanalyze the length of the major chain of polyprenol and dolichol from several plant leaves, including mangrove plants, as well as from animal and fish livers by 2D-TLC. Polyprenol- and dolichol-derived metabolites such as polyprenylacetone and epoxydolichol were found together with rubber-like prenol. This review focuses on analyses of polyprenol and its derivatives, including recently found epoxypolyprenol and polyprenylacetone. Attention has also been paid to the chromatographic behavior of rubber-like prenol on TLC.

Abstract
A procedure for the preparation of (S)-dolichol and (S)-nor-dolichol starting from the polyprenyl fraction extracted from Gingko Biloba integer or extracted leaves is described. Two chiral isoprenoid compounds in good yields and high degree of enantiomeric excess were obtained. The (S)-nordolichol appears to be a good chiral precursor for the preparation of 14C-labeled (S)-dolichol which is to be used in investigations aimed at gaining further information with respect to the role of dolichol in the function of living cells.

Abstract
In eukaryotes, dolichols (C(70-120)) play indispensable roles as glycosyl carrier lipids in the biosynthesis of glycoproteins on endoplasmic reticulum. In addition to dolichols, seed plants have other types of Z,E-mixed polyisoprenoids termed ficaprenol (tri-trans,poly-cis-polyprenol, C(45-75)) and betulaprenol (di-trans,poly-cis-polyprenol, C(30-45) and C(≥70)) in abundance. However, the physiological significance of these polyprenols has not been elucidated because of limited information regarding cis-prenyltransferases (cPTs) which catalyze the formation of the structural backbone of Z,E-mixed polyisoprenoids. In the comprehensive identification and characterization of cPT homologues from Arabidopsis thaliana, AtHEPS was identified as a novel cis,trans-mixed heptaprenyl diphosphate synthase. AtHEPS heterologously expressed in Escherichia coli catalyzed the formation of C(35) polyisoprenoid as a major product, independent of the chain lengths of all-trans allylic primer substrates. Kinetic analyses revealed that farnesyl diphosphate was the most favorable for AtHEPS among the allylic substrates tested suggesting that AtHEPS was responsible for the formation of C(35) betulaprenol. AtHEPS partially suppressed the phenotypes of a yeast cPT mutant deficient in the biosynthesis of dolichols. Moreover, in A. thaliana cells, subcellular localization of AtHEPS on the endoplasmic reticulum was shown by using green fluorescent protein fused proteins. However, a cold-stress-inducible expression of AtHEPS suggested that AtHEPS and its product might function in response to abiotic stresses rather than in cell maintenance as a glycosyl carrier lipid on the endoplasmic reticulum.

Abstract
The development of new drugs is one strategy for malaria control. Biochemical pathways localised in the apicoplast of the parasite, such as the synthesis of isoprenic precursors, are excellent targets because they are different or absent in the human host. Isoprenoids are a large and highly diverse group of natural products with many functions and their synthesis is essential for the parasite's survival. During the last few years, the genes, enzymes, intermediates and mechanisms of this biosynthetic route have been elucidated. In this review, we comment on some aspects of the methylerythritol phosphate pathway and discuss the presence of diverse isoprenic products such as dolichol, ubiquinone, carotenoids, menaquinone and isoprenylated proteins, which are biosynthesised during the intraerythrocytic stages of Plasmodium falciparum.

Abstract
Cancer and degenerative diseases are major causes of morbidity and death, derived from the permanent modification of key biopolymers such as DNA and regulatory proteins by usually smaller, reactive molecules, present in the environment or generated from endogenous and xenobiotic components by the body's own biochemical mechanisms (molecular adducts). In particular, protein adducts with organic electrophiles have been studied for more than 30 [see, e.g., Calleman et al., 1978] years essentially for three purposes: (a) as passive monitors of the mean level of individual exposure to specific chemicals, either endogenously present in the human body or to which the subject is exposed through food or environmental contamination; (b) as quantitative indicators of the mean extent of the individual metabolic processing which converts a non-reactive chemical substance into its toxic products able to damage DNA (en route to cancer induction through genotoxic mechanisms) or key proteins (as in the case of several drugs, pesticides or otherwise biologically active substances); (c) to relate the extent of protein modification to that of biological function impairment (such as enzyme inhibition) finally causing the specific health damage. This review describes the role that contemporary mass spectrometry-based approaches employed in the qualitative and quantitative study of protein-electrophile adducts play in the discovery of the (bio)chemical mechanisms of toxic substances and highlights the future directions of research in this field. A particular emphasis is given to the measurement of often high levels of the protein adducts of several industrial and environmental pollutants in unexposed human populations, a phenomenon which highlights the possibility that a number of small organic molecules are generated in the human organism through minor metabolic processes, the imbalance of which may be the cause of "spontaneous" cases of cancer and of other degenerative diseases of still uncharacterized etiology. With all this in mind, it is foreseen that a holistic description of cellular functions will take advantage of new analytical methods based on time-integrated metabolomic measurements of a new biological compartment, the "adductome," aimed at better understanding integrated organism response to environmental and endogenous stressors.

Abstract
Direct analysis of polyisoprenoid alcohols by electrospray ionization mass spectrometry (ESI-MS) often produces poor results requiring off-line time- and sample-consuming derivatization techniques. In this chapter, we describe a simple ESI-MS approach for the direct analysis of polyisoprenoid alcohols from biological samples. Lithium iodide is used to promote cationization by intense formation of [M+Li](+) adducts. Detection of polyisoprenoids with mass determination can thus be performed with high sensitivity (LOD near 100 pM), whereas characteristic collision-induced dissociations observed for both dolichols and polyprenols permit investigation of their structure. We also describe a simple ESI-MS approach for the direct analysis of carotenoids in biological samples using lithium iodide to promote their ionization and the analysis of several carotenoids as proof-of-principle cases. Finally, we applied ESI(Li(+))-MS and ESI(Li(+))-MS/MS to investigate the presence of carotenoids in Plasmodium falciparum.

Abstract
We performed reverse-phase thin-layer chromatography and reverse-phase high-performance liquid chromatography (RP-HPLC) analysis of polyisoprenoids released by sulfonium-salt cleavage with methyl iodide from Plasmodium falciparum proteins labeled with [3H]FPP or [3H]GGPP and showed that a dolichol of 11 isoprene units is bound to 21-28-kDa protein clusters from trophozoite and schizont stages. The dolichol structure was confirmed by electrospray-ionization mass spectrometry analysis. Treatment with protein synthesis inhibitors and RP-HPLC analysis of the proteolytic digestion products from parasite proteins labeled with [35S]cysteine and [3H]FPP showed that the attachment of dolichol to protein is a post-translational event and probably occurs via a covalent bond to cysteine residues.

Abstract
Isoprenoid lipids were found to be covalently linked to proteins of Arabidopsis thaliana. Their identity (polyprenols: Prenol-9-11 with Pren-10 dominating and dolichols: Dol-15-17 with Dol-16 dominating) was confirmed by means of HPLC/ESI-MS with application of the multiple reaction monitoring technique as well as metabolic labeling of Arabidopsis plants with [(3)H]mevalonate and other precursors. The occurrence of typical farnesol-, geranylgeraniol-, and phytol-modified proteins was also noted. Radioisotopic labeling allowed detection of several proteins that were covalently bound to mevalonate-derived isoprenoid alcohols. A significant portion of polyisoprenylated proteins was recovered in the cytosolic/light vesicular fraction of Arabidopsis cells upon subfractionation. Taken together our data prove that a subset of plant proteins is polyisoprenylated.

Abstract
Polyisoprenoid alcohols of the plant Coluria geoides were isolated and analyzed by HPLC with UV detection to determine the nature of the polyprenol and dolichol mixture in the organs studied. In roots, a family of dolichols (Dol-15 to Dol-23, with Dol-16 dominating, where Dol-n is dolichol composed of n isoprene units) was accompanied by traces of polyprenols of similar chain lengths, whereas in hairy roots grown in vitro, identical patterns with a slightly broader chain-length range were found. Conversely, in leaves and seeds polyprenols were the dominant form, and their pattern was shifted toward longer chains (maximal content of Pren-19, where Pren-n is polyprenol composed of n isoprene units). Interestingly, the pattern of dolichols in seeds and leaves (in which Dol-17 dominated) was similar to that found in roots. Structures of the dolichols and polyprenols isolated were confirmed by the application of a new HPLC/electrospray ionization-MS method, which also offers a much higher sensitivity in detection of these compounds compared to a UV detector. The highest sensitivity was obtained when the [M + Na]+ ions of polyprenols and dolichols were recorded in the selected ion monitoring mode and a small amount of sodium acetate solution was added post-column to enhance the formation of these ions in an electrospray ion source.

Abstract
Extensive protease digestion of delipidated [3H]mevalonate (MVA)-labeled proteins, followed by HPLC separation of the products, is one approach to identify and study prenyl cysteines. Using this methodology three major [3H]MVA-labeled peaks appeared. Two of them represent farnesyl cysteine (FC) and geranylgeranyl cysteine (GGC). The third peak represents unknown products that are considerably more hydrophobic than FC and GGC, here designated HPC. Previously, we provided evidence that cysteine residues may also be modified by dolichyl groups. Dolichyl cysteines (DolC) belong to HPC. However, as shown in the present study, DolC only represents a minor portion of HPC. Data obtained from different sets of experiments, including [3H]GGOH-labeling and use of prenyl transferase inhibitors, suggest that HPC mainly involves CXC or CC residues with double-linked GG groups. In turn this points to the possibility that proteins modified by double GG groups are quite common, and may probably involve other proteins than the rab family of GTPases.

Abstract
Isoprenylation is an essential protein modification in eukaryotic cells. Herein, we report that in Plasmodium falciparum, a number of proteins were labeled upon incubation of intraerythrocytic forms with either [(3)H]farnesyl pyrophosphate or [(3)H]geranylgeranyl pyrophosphate. By thin-layer chromatography, we showed that attached isoprenoids are partially modified to dolichol and other, uncharacterized, residues, confirming active isoprenoid metabolism in this parasite. Incubation of blood-stage P. falciparum treated with the isoprenylation inhibitor limonene significantly decreased the parasites' progression from the ring stage to the trophozoite stage and at 1.22 mM, 50% of the parasites died after the first cycle. Using Ras- and Rap-specific monoclonal antibodies, putative Rap and Ras proteins of P. falciparum were immunoprecipitated. Upon treatment with 0.5 mM limonene, isoprenylation of these proteins was significantly decreased, possibly explaining the observed arrest of parasite development.

Abstract
The numbers of isoprene residues and unsaturated bonds, cis/trans configuration, and head group polarity influence the tumor-suppressive potency of acyclic isoprenoid hydrocarbons and alcohols; within the series tested, trans, trans farnesol had the greatest potency. Geraniol esters had increased potency relative to that of the free alcohol. Farnesyl anthranilate induced a concentration-dependent decrease in the B16 melanoma cell population, in part due to an increased proportion of cells in the G1 phase of the cell cycle and in part by the increased the proportion of apoptotic cells. Farnesyl anthranilate (1.5 mmol/kg diet) significantly suppressed the growth of implanted B16 melanomas and lowered the plasma cholesterol levels of tumor-free mice.

Abstract
Lipophilic peptides and proteins present specific problems during preparation and analysis which require the use of modified methodology. This chapter discusses some of the methods that have been employed in the isolation and structural studies of the pulmonary surfactant-associated proteins B and C (SP-B and SP-C), other proteins with lipid-like physicochemical properties, and the SP-B precursor. In particular, methods for separation and analysis of peptide/lipid mixtures, high-resolution separation of lipopeptides, analysis of fatty acylated peptides, and secondary and tertiary structure analysis of lipopeptides are discussed.

Abstract
Protein prenylation in plants was studied by in vivo metabolic (3)H-mevalonate labeling in combination with a range of protein synthesis inhibitors. In spinach cotyledons, this posttranslational protein modification was found to be divided into two categories, one representing the conventional prenylation involving farnesyl and geranylgeranyl groups bound to cysteine residues via thioether linkages. This category revealed a similar pattern of prenylated proteins to that observed in mammalian cells and depends on nuclear gene expression. The other category was shown to represent a type of prenylation confined to chloroplasts. It depends on plastid gene expression and does not involve a thioether bond. The modifying isoprenoid could be released from the chloroplastic polypeptides by alkaline treatment and was identified as phytol upon GC-MS analysis. The phytol could readily be derived from all-trans-[(3)H]farnesol, which, like all-trans-[(3)H]geranylgeraniol, was taken up by the cotyledons, resulting in incorporation of radiolabel into proteins.

Abstract
Farnesyl protein transferase (FPT) activity was measured in rat liver subcellular fractions by using an unspecific acceptor for the farnesyl groups. The highest specific activity was found in mitochondria and it exceeded that of the microsomes three-fold. Considerably lower specific activities were found in the nuclei and cytosol. Further subfractionation revealed that the mitochondrial FPT activity is located in the matrix. The beta-subunit of the mitochondrial enzyme has an apparent molecular mass of 46 kDa, which is similar to its cytosolic counterpart. The results suggest that protein farnesylation can take place in a number of subcellular organelles.

Abstract
In a previous study, we demonstrated the occurrence of novel proteins modified with a diphytanylglyceryl group in thioether linkage in Halobacterium halobium (Sagami, H., Kikuchi, A., and Ogura, K. (1995) J. Biol. Chem. 270, 14851-14854). In this study, we further investigated protein isoprenoid modification in this halobacterium using several radioactive tracers such as [3H]geranylgeranyl diphosphate. One of the radioactive bands observed on SDS-polyacrylamide gel electrophoresis corresponded to a periodic acid-Schiff stain-positive protein (200 kDa). Radioactive and periodic acid-Schiff stain-positive peptides (28 kDa) were obtained by trypsin digestion of the labeled proteins. The radioactive materials released by acid treatment of the peptides showed a similar mobility to dolichyl (C55) phosphate on a normal-phase thin-layer plate. However, radioactive hydrolysates obtained by acid phosphatase treatment co-migrated not with dolichol (C55-65), but with diphytanylglycerol on both reverse- and normal-phase thin-layer plates. The mass spectrum of the hydrolysate was also coincident with that of diphytanylglycerol. The partial amino acid sequences of the 28-kDa peptides were found in a fragment (amino acids 731-816) obtainable by trypsin cleavage of the known cell-surface glycoprotein of this halobacterium. These results indicate that the cell-surface glycoprotein (200 kDa) is modified with diphytanylglyceryl phosphate.
