Abstract
BACKGROUND Carotenoid cleavage oxygenases (CCOs) are a group of enzymes that catalyze the oxidative cleavage of carotenoid molecules. These enzymes widely exist in plants, fungi, and certain bacteria, and are involved in various biological processes. It would be of great importance and necessity to identify CCO members in birch and characterize their responses upon abiotic stresses. RESULTS A total of 16 BpCCOs, including 8 BpCCDs and 8 BpNCEDs were identified in birch, and phylogenetic tree analysis showed that they could be classified into six subgroups. Collinearity analysis revealed that BpCCOs have the largest number of homologous genes in Gossypium hirsutum and also have more homologous genes in other dicotyledons. In addition, promoter analysis revealed that the promoter regions of BpCCOs contained many abiotic stress-related and hormone-responsive elements. The results of qRT-PCR showed that most of the BpCCOs were able to respond significantly to ABA, PEG, salt and cold stresses. Finally, the prediction of the interacting proteins of BpCCOs by STRING revealed several proteins that may interact with BpCCOs and be involved in plant growth and development/abiotic stress processes, such as HEC1 (bHLH), ATABA1, ATVAMP714, etc. CONCLUSION: In this study, the CCO members were identified in birch in a genome-wide scale. These results indicate that BpCCO genes may play important roles in the abiotic stress responses of birch plants.

Abstract
BACKGROUND Crocin, a glycosylated apocarotenoid pigment predominantly found in saffron, has garnered significant interest in the field of biotechnology for its bioactive properties. Traditional production of crocins and their aglycone, crocetin, typically involves extraction from crocin-producing plants. This study aimed to develop an alternative biosynthetic method for these compounds by engineering the metabolic pathways of zeaxanthin, crocetin, and crocin in Escherichia coli strains. RESULTS Employing a series of genetic modifications and the strategic overexpression of key enzymes, we successfully established a complete microbial pathway for synthesizing crocetin and four glycosylated derivatives of crocetin, utilizing glycerol as the primary carbon source. The overexpression of zeaxanthin cleavage dioxygenase and a novel variant of crocetin dialdehyde dehydrogenase resulted in a notable yield of crocetin (34.77 ± 1.03 mg/L). Further optimization involved the overexpression of new types of crocetin and crocin-2 glycosyltransferases, facilitating the production of crocin-1 (6.29 ± 0.19 mg/L), crocin-2 (5.29 ± 0.24 mg/L), crocin-3 (1.48 ± 0.10 mg/L), and crocin-4 (2.72 ± 0.13 mg/L). CONCLUSIONS This investigation introduces a pioneering and integrated microbial synthesis method for generating crocin and its derivatives, employing glycerol as a sustainable carbon feedstock. The substantial yields achieved highlight the commercial potential of microbial-derived crocins as an eco-friendly alternative to plant extraction methods. The development of these microbial processes not only broadens the scope for crocin production but also suggests significant implications for the exploitation of bioengineered compounds in pharmaceutical and food industries.

Abstract
A novel bacterium, designated TRT317T, was isolated from saline-alkaline soil collected from the Pamir plateau in northwest China. Cells of this strain were Gram-stain-negative, aerobic rods and red-pink-coloured. Phylogenetic analysis using 16S rRNA gene sequences indicated that strain TRT317T showed the highest sequence similarity to the type strains of
Pontibacter diazotrophicus
(96.3 %) and
Pontibacter yuliensis
(96.2 %). Growth was observed at 4–40 °C, pH 6.0–10.0 and in the presence of up to 7 % (w/v) NaCl. The major fatty acids were iso-C15 : 0 and summed feature 4 (iso-C17 : 1 I/anteiso-C17 : 1 B). The polar lipids included phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one unidentified phospholipid, four unidentified glycolipids and five unidentified lipids. The whole-cell sugars of strain TRT317T were mannose, rhamnose, glucose, galactose, xylose, arabinose and four unidentified sugars. The sole respiratory quinone was MK-7. The genomic DNA G+C content of strain TRT317T was 47.7 mol%. The average nucleotide identity (ANI) value of strain TRT317T with
P. diazotrophicus
was 88.3 %, which is below the standard ANI threshold for species identification (95–96 %). Combined results of physiological, genotypic, phylogenetic and chemotaxonomic analyses demonstrated that strain TRT317T represents a novel species within the genus
Pontibacter
, for which the name Pontibacter pamirensis sp. nov. is proposed. The type strain is TRT317T (=CGMCC1.18690T=KCTC 82818T).

Abstract
Natural carotenoids are secondary metabolites that exhibit antioxidant, anti-inflammatory, and anti-cancer properties. These types of compounds are highly demanded by pharmaceutical, cosmetic, nutraceutical, and food industries, leading to the search for new natural sources of carotenoids. In recent years, the production of carotenoids from bacteria has become of great interest for industrial applications. In addition to carotenoids with C40-skeletons, some bacteria have the ability to synthesize characteristic carotenoids with C30-skeletons. In this regard, a great variety of methodologies for the extraction and identification of bacterial carotenoids has been reported and this is the first review that condenses most of this information. To understand the diversity of carotenoids from bacteria, we present their biosynthetic origin in order to focus on the methodologies employed in their extraction and characterization. Special emphasis has been made on high-performance liquid chromatography-mass spectrometry (HPLC-MS) for the analysis and identification of bacterial carotenoids. We end up this review showing their potential commercial use. This review is proposed as a guide for the identification of these metabolites, which are frequently reported in new bacteria strains.

Abstract
Planococcus faecalis AJ003T produces glycosyl-4,4′-diaponeurosporen-4′-ol-4-oic acid as its main carotenoid. Five carotenoid pathway genes were presumed to be present in the genome of P. faecalis AJ003T; however, 4,4-diaponeurosporene oxidase (CrtP) was non-functional, and a gene encoding aldehyde dehydrogenase (AldH) was not identified. In the present study, a genome mining approach identified two missing enzymes, CrtP2 and AldH2454, in the glycosyl-4,4′-diaponeurosporen-4′-ol-4-oic acid biosynthetic pathway. Moreover, CrtP2 and AldH enzymes were functional in heterologous Escherichia coli and generated two carotenoid aldehydes (4,4′-diapolycopene-dial and 4,4′-diaponeurosporene-4-al) and two carotenoid carboxylic acids (4,4′-diaponeurosporenoic acid and 4,4′-diapolycopenoic acid). Furthermore, the genes encoding CrtP2 and AldH2454 were located at a distance the carotenoid gene cluster of P. faecalis.

Abstract
The carotenoids are terpenoid fat-soluble pigments produced by plants, algae, and several bacteria and fungi. They are ubiquitous components of animal diets. Carotenoid cleavage oxygenase (CCO) superfamily members are involved in carotenoid metabolism and are present in all kingdoms of life. Throughout the animal kingdom, carotenoid oxygenases are widely distributed and they are completely absent only in two unicellular organisms, Monosiga and Leishmania. Mammals have three paralogs 15,15'-β-carotene oxygenase (BCO1), 9',10'-β-carotene oxygenase (BCO2) and RPE65. The first two enzymes are classical carotenoid oxygenases: they cleave carbon‑carbon double bonds and incorporate two atoms of oxygen in the substrate at the site of cleavage. The third, RPE65, is an unusual family member, it is the retinoid isomerohydrolase in the visual cycle that converts all-trans-retinyl ester into 11-cis-retinol. Here we discuss evolutionary aspects of the carotenoid cleavage oxygenase superfamily and their enzymology to deduce what insight we can obtain from their evolutionary conservation.

Abstract
Apocarotenoids are important signaling molecules generated from carotenoids through the action of carotenoid cleavage dioxygenases (CCDs). These enzymes have a remarkable ability to cleave carotenoids at specific alkene bonds while leaving chemically similar sites within the polyene intact. Although several bacterial and eukaryotic CCDs have been characterized, the long-standing goal of experimentally visualizing a CCD-carotenoid complex at high resolution to explain this exquisite regioselectivity remains unfulfilled. CCD genes are also present in some archaeal genomes, but the encoded enzymes remain uninvestigated. Here, we address this knowledge gap through analysis of a metazoan-like archaeal CCD from Candidatus Nitrosotalea devanaterra (NdCCD). NdCCD was active toward β-apocarotenoids but did not cleave bicyclic carotenoids. It exhibited an unusual regiospecificity, cleaving apocarotenoids solely at the C14'-C13' alkene bond to produce β-apo-14'-carotenals. The structure of NdCCD revealed a tapered active site cavity markedly different from the broad active site observed for the retinal-forming Synechocystis apocarotenoid oxygenase (SynACO) but similar to the vertebrate retinoid isomerase RPE65. The structure of NdCCD in complex with its apocarotenoid product demonstrated that the site of cleavage is defined by interactions along the substrate binding cleft as well as selective stabilization of reaction intermediates at the scissile alkene. These data on the molecular basis of CCD catalysis shed light on the origins of the varied catalytic activities found in metazoan CCDs, opening the possibility of modifying their activity through rational chemical or genetic approaches.

Abstract
Carotenoids in cyanobacteria play an important role in protecting against and in repairing damage against low level UV-B radiation. Here we use transcriptomics and metabolomic HPLC pigment analysis to compare carotenoid pathway regulation in the filamentous cyanobacterium Chlorogloeopsis fritschii PCC 6912 exposed to white light and to white light supplemented with low level UV-B. Under UV-B changes in carotenoid transcription regulation were found associated with carotenogenesis (carotenoid synthesis), photoprotection and carotenoid cleavage. Transcriptional regulation was reflected in corresponding pigment signatures. All carotenogenesis pathway genes from geranylgeranyl-diphosphate to lycopene were upregulated. There were significant increases in expression of gene homologs (crtW, crtR, cruF, and cruG) associated with routes to ketolation to produce significant increases in echinenone and canthaxanthin concentrations. There were gene homologs for four β-carotene-ketolases (crtO and crtW) present but only one crtW was upregulated. Putative genes encoding enzymes (CruF, CrtR, and CruG) for the conversion of γ-carotene to myxol 2'-methylpentoside were upregulated. The hydroxylation pathway to nostaxanthin via zeaxanthin and caloxanthin (gene homologs for CrtR and CrtG) were not upregulated, reflected in the unchanged corresponding pigment concentrations in zeaxanthin, caloxanthin and nostaxanthin, Transcripts for the non-photochemical quenching related Orange-Carotenoid-Protein (OCP) and associated Fluoresence-Recovery-Protein (FRP) associated with photoprotection were upregulated, and one carotenoid binding Helical-Carotenoid-Protein (HCP) gene homolog was downregulated. Multiple copies of genes encoding putative apocarotenoid related carotenoid oxygenases responsible for carotenoid cleavage were identified, including an upregulated apo-β-carotenal-oxygenase gene homologous to a retinal producing enzyme. Our study provides holistic insight into the photoregulatory processes that modulate the synthesis, photoprotection and cleavage of carotenoids in cyanobacterial cells exposed to low level UV-B. This is important to understanding how regulation of metabolism responds to a changing environment and how metabolism can be modulated for biotechnological purposes.

Abstract
Carotenoid cleavage dioxygenases (CCDs) comprise a superfamily of mononuclear non-heme iron proteins that catalyze the oxygenolytic fission of alkene bonds in carotenoids to generate apocarotenoid products. Some of these enzymes exhibit additional activities such as carbon skeleton rearrangement and trans-cis isomerization. The group also includes a subfamily of enzymes that split the interphenyl alkene bond in molecules such as resveratrol and lignostilbene. CCDs are involved in numerous biological processes ranging from production of light-sensing chromophores to degradation of lignin derivatives in pulping waste sludge. These enzymes exhibit unique features that distinguish them from other families of non-heme iron enzymes. The distinctive properties and biological importance of CCDs have stimulated interest in their modes of catalysis. Recent structural, spectroscopic, and computational studies have helped clarify mechanistic aspects of CCD catalysis. Here, we review these findings emphasizing common and unique properties of CCDs that enable their variable substrate specificity and regioselectivity.

Abstract
In many pro- and eukaryotes, a retinal-based proton pump equips the cell to drive ATP synthesis with (sun)light. Such pumps, therefore, have been proposed as a plug-in for cyanobacteria to artificially increase the efficiency of oxygenic photosynthesis. However, little information on the metabolism of retinal, their chromophore, is available for these organisms. We have studied the in vivo roles of five genes (sll1541, slr1648, slr0091, slr1192, and slr0574) potentially involved in retinal metabolism in Synechocystis sp. strain PCC 6803. With a gene deletion approach, we have shown that Synechocystis apo-carotenoid-15,15-oxygenase (SynACO), encoded by gene sll1541, is an indispensable enzyme for retinal synthesis in Synechocystis, presumably via asymmetric cleavage of β-apo-carotenal. The second carotenoid oxygenase (SynDiox2), encoded by gene slr1648, competes with SynACO for substrate(s) but only measurably contributes to retinal biosynthesis in stationary phase via an as-yet-unknown mechanism. In vivo degradation of retinal may proceed through spontaneous chemical oxidation and via enzyme-catalyzed processes. Deletion of gene slr0574 (encoding CYP120A1), but not of slr0091 or of slr1192, causes an increase (relative to the level in wild-type Synechocystis) in the retinal content in both the linear and stationary growth phases. These results suggest that CYP120A1 does contribute to retinal degradation. Preliminary data obtained using 13C-labeled retinal suggest that conversion to retinol and retinoic acid and subsequent further oxidation also play a role. Deletion of sll1541 leads to deficiency in retinal synthesis and allows the in vivo reconstitution of far-red-absorbing holo-proteorhodopsin with exogenous retinal analogues, as demonstrated here for all-trans 3,4-dehydroretinal and 3-methylamino-16-nor-1,2,3,4-didehydroretinal.IMPORTANCE Retinal is formed by many cyanobacteria and has a critical role in most forms of life for processes such as photoreception, growth, and stress survival. However, the metabolic pathways in cyanobacteria for synthesis and degradation of retinal are poorly understood. In this paper we identify genes involved in its synthesis, characterize their role, and provide an initial characterization of the pathway of its degradation. This led to the identification of sll1541 (encoding SynACO) as the essential gene for retinal synthesis. Multiple pathways for retinal degradation presumably exist. These results have allowed us to construct a strain that expresses a light-dependent proton pump with an action spectrum extending beyond 700 nm. The availability of this strain will be important for further work aimed at increasing the overall efficiency of oxygenic photosynthesis.

Phylogenetic analysis of the metazoan carotenoid oxygenase superfamily: a new ancestral gene assemblage of BCO-like (BCOL) proteins. Sci Rep 2017; 7:13192. [PMID: 29038443 PMCID: PMC5643517 DOI: 10.1038/s41598-017-13521-x] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2017] [Accepted: 09/25/2017] [Indexed: 11/08/2022] Open
Abstract
Here we describe a new family of carotenoid cleavage oxygenases (CCOs) in metazoans, the BCO2-like (BCOL) clade, which contains lancelet, nematode, and molluscan carotenoid oxygenase sequences. Phylogenetic analysis of CCOs in all kingdoms of life confirmed that the BCOL enzymes are an independent clade of ancient origin. One of the predicted lancelet BCOL proteins, cloned and analyzed for carotenoid cleavage activity in a bacterial carotenoid expression system, had activity similar to lancelet BCO2 proteins, although with a preference for cis isomers. Our docking predictions correlated well with the cis-favored activity. The extensive expansions of the new animal BCOL family in some species (e.g., lancelet) suggests that the carotenoid cleavage oxygenase superfamily has evolved in the “extremely high turnover” fashion: numerous losses and duplications of this family are likely to reflect complex regulation processes during development, and interactions with the environment. These findings also serve to provide a rationale for the evolution of the BCO-related outlier RPE65 retinol isomerase, an enzyme that does not utilize carotenoids as substrate or perform double-bond cleavage.

Abstract
Carotenoids are essential for photosynthesis and photoprotection in photosynthetic organisms and beneficial for human health. Apocarotenoids derived from carotenoid degradation can serve critical functions including hormones, volatiles, and signals. They have been used commercially as food colorants, animal feed supplements, and nutraceuticals for cosmetic and pharmaceutical purposes. This review focuses on the molecular evolution of carotenogenic enzymes and carotenoid cleavage oxygenases (CCOs) from bacteria, fungi, cyanobacteria, algae, and plants. The diversity of carotenoids and apocarotenoids as well as their complicated biosynthetic pathway in different species can shed light on the history of early molecular evolution. Some carotenogenic genes (such as phytoene synthases) have high protein sequence similarity from bacteria to land plants, but some (such as phytoene desaturases, lycopene cyclases, carotenoid hydroxylases, and CCOs) have low similarity. The broad diversity of apocarotenoid volatile compounds can be attributed to large numbers of carotenoid precursors and the various cleavage sites catalyzed by CCOs enzymes. A variety of carotenogenic enzymes and CCOs indicate the functional diversification of carotenoids and apocrotenoids in different species. New carotenoids, new apocarotenoids, new carotenogenic enzymes, new CCOs, and new pathways still need to be explored.

Abstract
Apocarotenoids are carotenoid-derived compounds widespread in all major taxonomic groups, where they play important roles in different physiological processes. In addition, apocarotenoids include compounds with high economic value in food and cosmetics industries. Apocarotenoid biosynthesis starts with the action of carotenoid cleavage dioxygenases (CCDs), a family of non-heme iron enzymes that catalyze the oxidative cleavage of carbon-carbon double bonds in carotenoid backbones through a similar molecular mechanism, generating aldehyde or ketone groups in the cleaving ends. From the identification of the first CCD enzyme in plants, an increasing number of CCDs have been identified in many other species, including microorganisms, proving to be a ubiquitously distributed and evolutionarily conserved enzymatic family. This review focuses on CCDs from plants, algae, fungi, and bacteria, describing recent progress in their functions and regulatory mechanisms in relation to the different roles played by the apocarotenoids in these organisms.

Abstract
Recent research interest in phytochemicals has consistently driven the efforts in the metabolic engineering field toward microbial production of various carotenoids. In spite of systematic studies, the possibility of using C30 carotenoids as biologically functional compounds has not been explored thus far. Here, we generated 13 novel structures of C30 carotenoids and one C35 carotenoid, including acyclic, monocyclic, and bicyclic structures, through directed evolution and combinatorial biosynthesis, in Escherichia coli. Measurement of radical scavenging activity of various C30 carotenoid structures revealed that acyclic C30 carotenoids showed higher radical scavenging activity than did DL-α-tocopherol. We could assume high potential biological activity of the novel structures of C30 carotenoids as well, based on the neuronal differentiation activity observed for the monocyclic C30 carotenoid 4,4′-diapotorulene on rat bone marrow mesenchymal stem cells. Our results demonstrate that a series of structurally novel carotenoids possessing biologically beneficial properties can be synthesized in E. coli.

Abstract
Taxonomic studies were performed on a novel carotenoid-producing strain, designated AJ003T, isolated from faeces of Antarctic penguins. Cells of strain AJ003T were aerobic, Gram-stain-positive, cocci-shaped and orange. Strain AJ003T was capable of growing in a broad temperature range, including sub-zero growth (below − 20 to 30 °C). 16S rRNA gene sequence analysis revealed that strain AJ003T was closely related to Planococcus halocryophilus Or1T (97.4 % similarity), Planococcus antarcticus DSM 14505T (97.3 %), Planococcus kocurii NCIMB 629T (97.3 %), and Planococcus donghaensis JH1T (97.1 %). The predominant cellular fatty acids were anteiso-C15 : 0, and iso-C16 : 0.MK-7 and MK-8 were the quinones identified, and the major pigment was glycosyl-4,4′-diaponeurosporen-4′-ol-4-oic acid. The major polar lipid was phosphatidylglycerol. DNA–DNA relatedness of strain AJ003T with respect to its closest phylogenetic neighbours was 38.2 ± 0.5 % for Planococcus halocryophilus DSM 24743T, 32.2 ± 0.2 % for Planococcus antarcticus DSM 14505T, 21.0 ± 0.3 % for Planococcus kocurii DSM 20747T and 18.6 ± 1.4 % for Planococcus donghaensis KCTC 13050T. The DNA G+C content of strain AJ003T was 40.0 ± 0.6 mol%. Based on the phenotypic, chemotaxonomic and phylogenetic data, strain AJ003T is concluded to represent a novel species of the genus Planococcus, for which the name Planococcus faecalis sp. nov. is proposed. The type strain is AJ003T ( = KCTC 33580T = CECT 8759T).
