Sandmann G. Genes and Pathway Reactions Related to Carotenoid Biosynthesis in Purple Bacteria. BIOLOGY 2023; 12:1346. [PMID: 37887056 PMCID: PMC10604819 DOI: 10.3390/biology12101346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 10/11/2023] [Accepted: 10/16/2023] [Indexed: 10/28/2023]
Abstract
In purple bacteria, the genes of the carotenoid pathways are part of photosynthesis gene clusters which were distributed among different species by horizontal gene transfer. Their close organisation facilitated the first-time cloning of carotenogenic genes and promoted the molecular investigation of spheroidene and spirilloxanthin biosynthesis. This review highlights the cloning of the spheroidene and spirilloxanthin pathway genes and presents the current knowledge on the enzymes involved in the carotenoid biosynthesis of purple sulphur and non-sulphur bacteria. Mostly, spheroidene or spirilloxanthin biosynthesis exists in purple non-sulphur bacteria but both pathways operate simultaneously in Rubrivivax gelatinosus. In the following years, genes from other bacteria including purple sulphur bacteria with an okenone pathway were cloned. The individual steps were investigated by kinetic studies with heterologously expressed pathway genes which supported the establishment of the reaction mechanisms. In particular, the substrate and product specificities revealed the sequential order of the speroidene and spiriloxanthin pathways as well as their interactions. Information on the enzymes involved revealed that the phytoene desaturase determines the type of pathway by the formation of different products. By selection of mutants with amino acid exchanges in the putative substrate-binding site, the neurosporene-forming phytoene desaturase could be changed into a lycopene-producing enzyme and vice versa. Concerning the oxygen groups in neurosporene and lycopene, the tertiary alcohol group at C1 is formed from water and not by oxygenation, and the C2 or C4 keto groups are inserted differently by an oxygen-dependent or oxygen-independent ketolation reaction, respectively.

Microorganisms 2023; 11:microorganisms11020266. [PMID: 36838230 PMCID: PMC9967899 DOI: 10.3390/microorganisms11020266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Revised: 01/01/2023] [Accepted: 01/04/2023] [Indexed: 01/22/2023] Open
Abstract
Sphingomonas morindae sp. NBD5, which we previously identified and tested, is a new bacterial strain for producing lutein. Here, based on the next-generation sequencing technology, we analyzed high throughput genomic sequences and compared related functional genes of Sphingomonas morindae sp. NBD5 and Sphingopyxis sp. USTB-05. The genome of Sphingomonas morindae sp. NBD5 has two sets of chromosomes, which is 4,239,716 bp and harbors 3882 protein coding genes. There are 59 protein-coding genes related to the macular pigment (MP) biosynthesis, of which four genes (ackA, pgm, gpmI and pckA) are unique. These genes, pckG, porB, meh, and fldA, are unique in Sphingopyxis sp. USTB-05. The analysis of Sphingomonas morindae sp. NBD5 and Sphingopyxis sp. USTB-05 genomes gives an insight into the new pathway for MP production. These genes for the transformation of glucose to MP were also found in Sphingomonas morindae sp. NBD5 and Sphingopyxis sp. USTB-05. This study expands the understanding of the pathway for complete biosynthesis of MP by Sphingomonas morindae sp. NBD5 and Sphingopyxis sp. USTB-05.

Abstract
Unpredictable climate change might cause serious lack of food in the world. Therefore, in the present world, it is urgent to prepare countermeasures to solve problems in terms of human survival. In this research, quantitative trait loci (QTLs) were analyzed when rice attacked by white backed planthopper (WBPH) were analyzed using 120 Cheongcheong/Nagdong double haploid lines. Moreover, from the detected QTLs, WBPH resistance-related genes were screened in large candidate genes. Among them, OsCM, a major gene in the synthesis of Cochlioquinone-9 (cq-9), was screened. OsCM has high homology with the sequence of chorismate mutase, and exists in various functional and structural forms in plants that produce aromatic amino acids. It also induces resistance to biotic stress through the synthesis of secondary metabolites in plants. The WBPH resistance was improved in rice overexpressed through map-based cloning of the WBPH resistance-related gene OsCM, which was finally detected by QTL mapping. In addition, cq-9 increased the survival rate of caecal ligation puncture (CLP)-surgery mice by 60%. Moreover, the aorta of rat treated with cq-9 was effective in vasodilation response and significantly reduced the aggregation of rat platelets induced by collagen treatment. A cq-9, which is strongly associated with resistance to WBPH in rice, is also associated with positive effect of CLP surgery mice survival rate, vasodilation, and significantly reduced rat platelet aggregation induced by collagen treatment. Therefore, cq-9 presents research possibilities as a substance in a new paradigm that can act on both Plant-Insect in response to the present unpredictable future.

Abstract
Nowadays, carotenoid biosynthetic pathways are sufficiently elucidated at gene levels in bacteria, fungi, and higher plants. Also, in pathway engineering for isoprenoid (terpene) production, carotenoids have been one of the most studied targets. However, in 1988 when the author started carotenoid research, almost no carotenoid biosynthesis genes were identified. It was because carotenogenic enzymes are easily inactivated when extracted from their organism sources, indicating that their purification and the subsequent cloning of the corresponding genes were infeasible or difficult. On the other hand, natural product chemistry of carotenoids had advanced a great deal. Thus, those days, carotenoid biosynthetic pathways had been proposed based mainly on the chemical structures of carotenoids without findings on relevant enzymes and genes. This chapter shows what happened on carotenoid research, when carotenoid biosynthesis genes met non-carotenogenic Escherichia coli around 1990, followed by subsequent developments.

Abstract
Corynebacterium glutamicum, a yellow-pigmented soil bacterium that synthesizes the rare cyclic C50 carotenoid decaprenoxanthin and its glucosides, has been engineered for the production of various carotenoids. CrtE was assumed to be the major geranylgeranyl pyrophosphate (GGPP) synthase in carotenogenesis; however, deletion of crtE did not abrogate carotenoid synthesis. In silico analysis of the repertoire of prenyltransferases encoded by the C. glutamicum genome revealed two candidate GGPPS genes (idsA and ispB). The absence of pigmentation of an idsA deletion mutant and complementation experiments with a double deletion mutant lacking both idsA and crtE showed that IdsA is the major GGPPS of C. glutamicum and that crtE overexpression compensated for the lack of IdsA, whereas plasmid-borne overexpression of ispB did not. Purified His-tagged CrtE was active as a homodimer, whereas the active form of IdsA was homotetrameric. Both enzymes catalyzed prenyl transfer with isopentenyl pyrophosphate (IPP), dimethylallyl pyrophosphate, geranyl pyrophosphate and farnesylphosphate (FPP) as substrates. IdsA showed the highest catalytic efficiency with dimethylallyl pyrophosphate and IPP, whereas the catalytic efficiency of CrtE was highest with geranyl pyrophosphate and IPP. Finally, application of prenyltransferase overexpression revealed that combined overexpression of idsA and the IPP isomerase gene idi in the absence of crtE led to the highest decaprenoxanthin titer reported to date.

Abstract
We recently reported that the biosynthesis of fuscol, a diterpene from the octocoral Eunicea fusca, is inducible by the application of plant signaling factors such as salicylic acid to the coral's algal symbiont. In this study, an mRNA differential display approach has been employed with the dinoflagellate symbiont of this octocoral which has led to the isolation of a farnesyldiphosphate synthase (FPPS) that was transcriptionally activated under conditions that led to an induction of fuscol biosynthesis. Using a degenerate primer based on the aspartate-rich motifs found in prenylsynthases and a cassette ligation strategy, we report the cloning of the complete FPPS associated with the E. fusca dinoflagellate symbiont Symbiodinium sp. The protein exhibited the enzymatic properties associated with FPPS, namely, the synthesis of farnesyl diphosphate from geranyldiphosphate and isopentenyl diphosphate. The amino acid sequence of this FPPS has a high sequence similarity (82%) to known archaeal isoprenyl diphosphate synthases. This is the first description of a prokaryotic FPPS derived from a marine source.

Abstract
To determine whether Saccharomyces cerevisiae can serve as a host for efficient carotenoid and especially beta-carotene production, carotenogenic genes from the carotenoid-producing yeast Xanthophyllomyces dendrorhous were introduced and overexpressed in S. cerevisiae. Because overexpression of these genes from an episomal expression vector resulted in unstable strains, the genes were integrated into genomic DNA to yield stable, carotenoid-producing S. cerevisiae cells. Furthermore, carotenoid production levels were higher in strains containing integrated carotenogenic genes. Overexpression of crtYB (which encodes a bifunctional phytoene synthase and lycopene cyclase) and crtI (phytoene desaturase) from X. dendrorhous was sufficient to enable carotenoid production. Carotenoid production levels were increased by additional overexpression of a homologous geranylgeranyl diphosphate (GGPP) synthase from S. cerevisiae that is encoded by BTS1. Combined overexpression of crtE (heterologous GGPP synthase) from X. dendrorhous with crtYB and crtI and introduction of an additional copy of a truncated 3-hydroxy-3-methylglutaryl-coenzyme A reductase gene (tHMG1) into carotenoid-producing cells resulted in a successive increase in carotenoid production levels. The strains mentioned produced high levels of intermediates of the carotenogenic pathway and comparable low levels of the preferred end product beta-carotene, as determined by high-performance liquid chromatography. We finally succeeded in constructing an S. cerevisiae strain capable of producing high levels of beta-carotene, up to 5.9 mg/g (dry weight), which was accomplished by the introduction of an additional copy of crtI and tHMG1 into carotenoid-producing yeast cells. This transformant is promising for further development toward the biotechnological production of beta-carotene by S. cerevisiae.

Abstract
The isoprenoid pathway is a versatile biosynthetic network leading to over 23,000 compounds. Similar to other biosynthetic pathways, the production of isoprenoids in microorganisms is controlled by the supply of precursors, among other factors. To engineer a host that has the capability to supply geranylgeranyl diphosphate (GGPP), a common precursor of isoprenoids, we cloned and overexpressed isopentenyl diphosphate (IPP) isomerase (encoded by idi) from Escherichia coli and GGPP synthase (encoded by gps) from the archaebacterium Archaeoglobus fulgidus. The latter was shown to be a multifunctional enzyme converting dimethylallyl diphosphate (DMAPP) to GGPP. These two genes and the gene cluster (crtBIYZW) of the marine bacterium Agrobacterium aurantiacum were introduced into E. coli to produce astaxanthin, an orange pigment and antioxidant. This metabolically engineered strain produces astaxanthin 50 times higher than values reported before. To determine the rate-controlling steps in GGPP production, the IDI-GPS pathway was compared with another construct containing idi, ispA (encoding farnesyl diphosphate (FPP) synthase in E. coli), and crtE (encoding GGPP synthase from Erwinia uredovora). Results show that the conversion from FPP to GGPP is the first bottleneck, followed sequentially by IPP isomerization and FPP synthesis. Removal of these bottlenecks results in an E. coli strain providing sufficient precursors for in vivo synthesis of isoprenoids.

Abstract
Carotenoids represent one of the most widely distributed and structurally diverse classes of natural pigments, with important functions in photosynthesis, nutrition, and protection against photooxidative damage. In the eubacterial community, yellow, orange, and red carotenoids are produced by anoxygenic photosynthetic bacteria, cyanobacteria, and certain species of nonphotosynthetic bacteria. Many eukaryotes, including all algae and plants, as well as some fungi, also synthesize these pigments. In noncarotenogenic organisms, such as mammals, birds, amphibians, fish, crustaceans, and insects, dietary carotenoids and their metabolites also serve important biological roles. Within the last decade, major advances have been made in the elucidation of the molecular genetics, the biochemistry, and the regulation of eubacterial carotenoid biosynthesis. These developments have important implications for eukaryotes, and they make increasingly attractive the genetic manipulation of carotenoid content for biotechnological purposes.

Abstract
The crt gene clusters responsible for the biosynthesis of carotenoids such as lycopene, beta-carotene and astaxanthin have been isolated from carotenogenic bacteria such as Erwinia species and the marine bacterium Agrobacterium aurantiacum. The functions of the individual genes have been identified. The first substrate of the enzymes encoded by the Erwinia crt clusters is farnesyl pyrophosphate which is not only the precursor for carotenoid biosynthesis but also sterols, dolichols and other numerous isoprenoid compounds. Escherichia coli does not naturally synthesize carotenoids, but by using the carotenogenic genes recombinant strains accumulating lycopene, beta-carotene and astaxanthin have been produced. Other non-carotenogenic bacteria such as Zymomonas mobilis have also been engineered to produce beta-carotene by the introduction of the corresponding crt genes. A gene capable of enhancing carotenoid levels in E. coli has also been isolated from cDNA libraries of the yeast Phaffia rhodozyma and the green alga Haematococcus pluvialis. This gene has been found to encode an isopentenyl pyrophophate isomerase. It has further been shown that the edible yeasts Candida utilis as well as Saccharomyces cerevisiae, which possess no carotenoid biosynthetic pathway, acquire the ability to produce carotenoids, when the carotenogenic genes are expressed under the control of yeast-derived promoters and terminators. It has been observed in the yeasts S. cerevisiae and C. utilis carrying the lycopene biosynthesis genes that ergosterol content is decreased by 10 and 35%, respectively. It is therefore likely that the carbon flux for the ergosterol biosynthesis has been partially directed from farnesyl pyrophosphate to a new pathway for the lycopene biosynthesis. Further, the expression of a truncated gene which codes for the catalytic domain of the endogenous 3-hydroxy-3-methylglutaryl coenzyme. A reductase, has been found to be effective for enhancing carotenoid levels in the yeast C. utilis.

Abstract
Erwinia herbicola is a nonphotosynthetic bacterium that is yellow pigmented due to the presence of carotenoids. When the Erwinia carotenoid biosynthetic genes are expressed in Escherichia coli, this bacterium also displays a yellow phenotype. The DNA sequence of the plasmid pPL376, carrying the entire Erwinia carotenoid gene cluster, has been found to contain 12 open reading frames (ORFs). Six of the ORFs have been identified as carotenoid biosynthesis genes that code for all the enzymes required for conversion of farnesyl pyrophosphate (FPP) to zeaxanthin diglucoside via geranylgeranyl pyrophosphate, phytoene, lycopene, beta-carotene, and zeaxanthin. These enzymatic steps were assigned after disruption of each ORF by a specific mutation and analysis of the accumulated intermediates. Carotenoid intermediates were identified by the absorption spectra of the colored components and by high pressure liquid chromatographic analysis. The six carotenoid genes are arranged in at least two operons. The gene coding for beta-carotene hydroxylase is transcribed in the opposite direction from that of the other carotenoid genes and overlaps with the gene for phytoene synthase.
