Abstract
With the increase in clinical cases of bacterial infections with multiple antibiotic resistance, the world has entered a health crisis. Overuse, inappropriate prescribing, and lack of innovation of antibiotics have contributed to the surge of microorganisms that can overcome traditional antimicrobial treatments. In 2017, the World Health Organization published a list of pathogenic bacteria, including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Escherichia coli (ESKAPE). These bacteria can adapt to multiple antibiotics and transfer their resistance to other organisms; therefore, studies to find new therapeutic strategies are needed. One of these strategies is synthetic biology geared toward developing new antimicrobial therapies. Synthetic biology is founded on a solid and well-established theoretical framework that provides tools for conceptualizing, designing, and constructing synthetic biological systems. Recent developments in synthetic biology provide tools for engineering synthetic control systems in microbial cells. Applying protein engineering, DNA synthesis, and in silico design allows building metabolic pathways and biological circuits to control cellular behavior. Thus, synthetic biology advances have permitted the construction of communication systems between microorganisms where exogenous molecules can control specific population behaviors, induce intracellular signaling, and establish co-dependent networks of microorganisms.

Abstract
Microbial secondary metabolites are intensively explored due to their demands in pharmaceutical, agricultural and food industries. Streptomyces are one of the largest sources of secondary metabolites having diverse applications. In particular, the abundance of secondary metabolites encoding biosynthetic gene clusters and presence of wobble position in Streptomyces strains make it potential candidate as a native or heterologous host for secondary metabolite production including several cryptic gene clusters expression. Here, we have discussed the developments in Streptomyces strains genome mining, its exploration as a suitable host and application of synthetic biology for refactoring genetic systems for developing chassis for enhanced as well as novel secondary metabolites with reduced genome and cleaned background.

Abstract
Flavonoids, terpenoids, and polyketides are structurally diverse secondary metabolites used widely as pharmaceuticals and nutraceuticals. Most of these molecules exist in nature as glycosides, in which sugar residues act as a decisive factor in their architectural complexity and bioactivity. Engineering glycosylation through selective trimming or extension of the sugar residues in these molecules is a prerequisite to their commercial production as well to creating novel derivatives with specialized functions. Traditional chemical glycosylation methods are tedious and can offer only limited end-product diversity. New in vitro and in vivo biocatalytic tools have emerged as outstanding platforms for engineering glycosylation in these three classes of secondary metabolites to create a large repertoire of versatile glycoprofiles. As knowledge has increased about secondary metabolite-associated promiscuous glycosyltransferases and sugar biosynthetic machinery, along with phenomenal progress in combinatorial biosynthesis, reliable industrial production of unnatural secondary metabolites has gained momentum in recent years. This review highlights the significant role of sugar residues in naturally occurring flavonoids, terpenoids, and polyketide antibiotics. General biocatalytic tools used to alter the identity and pattern of sugar molecules are described, followed by a detailed illustration of diverse strategies used in the past decade to engineer glycosylation of these valuable metabolites, exemplified with commercialized products and patents. By addressing the challenges involved in current bio catalytic methods and considering the perspectives portrayed in this review, exceptional drugs, flavors, and aromas from these small molecules could come to dominate the natural-product industry.

New Sipanmycin Analogues Generated by Combinatorial Biosynthesis and Mutasynthesis Approaches Relying on the Substrate Flexibility of Key Enzymes in the Biosynthetic Pathway. Appl Environ Microbiol 2020; 86:AEM.02453-19. [PMID: 31732573 DOI: 10.1128/aem.02453-19] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Accepted: 11/08/2019] [Indexed: 12/12/2022] Open
Abstract
The appearance of new infectious diseases, the increase in multidrug-resistant bacteria, and the need for more effective chemotherapeutic agents have oriented the interests of researchers toward the search for metabolites with novel or improved bioactivities. Sipanmycins are disaccharyl glycosylated macrolactams that exert antibiotic and cytotoxic activities. By applying combinatorial biosynthesis and mutasynthesis approaches, we have generated eight new members of the sipanmycin family. The introduction of plasmids harboring genes responsible for the biosynthesis of several deoxysugars into sipanmycin-producing Streptomyces sp. strain CS149 led to the production of six derivatives with altered glycosylation patterns. After structural elucidation of these new metabolites, we conclude that some of these sugars are the result of the combination of the enzymatic machinery encoded by the introduced plasmids and the native enzymes of the d-sipanose biosynthetic pathway of the wild-type CS149 strain. In addition, two analogues of the parental compounds with a modified polyketide backbone were generated by a mutasynthesis approach, feeding cultures of a mutant strain defective in sipanmycin biosynthesis with 3-aminopentanoic acid. The generation of new sipanmycin analogues shown in this work relied on the substrate flexibility of key enzymes involved in sipanmycin biosynthesis, particularly the glycosyltransferase pair SipS9/SipS14 and enzymes SipL3, SipL1, SipL7, and SipL2, which are involved in the incorporation of the polyketide synthase starting unit.IMPORTANCE Combinatorial biosynthesis has proved its usefulness in generating derivatives of already known compounds with novel or improved pharmacological properties. Sipanmycins are a family of glycosylated macrolactams produced by Streptomyces sp. strain CS149, whose antiproliferative activity is dependent on the sugar moieties attached to the aglycone. In this work, we report the generation of several sipanmycin analogues with different deoxysugars, showing the high degree of flexibility exerted by the glycosyltransferase machinery with respect to the recognition of diverse nucleotide-activated sugars. In addition, modifications in the macrolactam ring were introduced by mutasynthesis approaches, indicating that the enzymes involved in incorporating the starter unit have a moderate ability to introduce different types of β-amino acids. In conclusion, we have proved the substrate flexibility of key enzymes involved in sipanmycin biosynthesis, especially the glycosyltransferases, which can be exploited in future experiments.

Abstract
Actinobacteria are characterized as the most prominent producer of natural products (NPs) with pharmaceutical importance. The production of NPs from these actinobacteria is associated with particular biosynthetic gene clusters (BGCs) in these microorganisms. The majority of these BGCs include polyketide synthase (PKS) or non-ribosomal peptide synthase (NRPS) or a combination of both PKS and NRPS. Macrolides compounds contain a core macro-lactone ring (aglycone) decorated with diverse functional groups in their chemical structures. The aglycon is generated by megaenzyme polyketide synthases (PKSs) from diverse acyl-CoA as precursor substrates. Further, post-PKS enzymes are responsible for allocating the structural diversity and functional characteristics for their biological activities. Macrolides are biologically important for their uses in therapeutics as antibiotics, anti-tumor agents, immunosuppressants, anti-parasites and many more. Thus, precise genetic/metabolic engineering of actinobacteria along with the application of various chemical/biological approaches have made it plausible for production of macrolides in industrial scale or generation of their novel derivatives with more effective biological properties. In this review, we have discussed versatile approaches for generating a wide range of macrolide structures by engineering the PKS and post-PKS cascades at either enzyme or cellular level in actinobacteria species, either the native or heterologous producer strains.

High-yield production of multiple O-methylated phenylpropanoids by the engineered Escherichia coli-Streptomyces cocultivation system. Microb Cell Fact 2019; 18:67. [PMID: 30971246 PMCID: PMC6456975 DOI: 10.1186/s12934-019-1118-9] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Accepted: 04/03/2019] [Indexed: 11/30/2022] Open
Abstract
Background O-Methylated phenylpropanoids, which are generally present in small amounts in plants, have improved or distinct biological activities and pharmacological properties as opposed to their unmethylated counterparts. Although microbial production could be a useful tool for the efficient and environment-friendly production of methylated phenylpropanoids, a high-yield microbial production of neither tri-methylated stilbenes nor di-/tri-methylated flavonoids has been achieved to date. Results A methyltransferase from Streptomyces avermitilis (SaOMT2), which has been known to possess 7-O-methylation activity toward several flavonoids, exhibited more diverse regiospecificity and catalyzed mono-, di-, and tri-methylation of stilbene, flavanone, and flavone when it was expressed in Streptomyces venezuelae. For the efficient production of multi-methylated phenylpropanoids, a cocultivation system was developed by employing engineered Escherichia coli strains producing pterostilbene, naringenin, and apigenin, respectively, along with SaOMT2-expressing S. venezuelae mutant. Consequently, high-yield microbial production of tri-methylated stilbenes and di-/tri-methylated flavonoids (including 3,5,4′-trimethoxystilbene, 5-hydroxy-7,4′-dimethoxyflavanone, 4′-hydroxy-5,7-dimethoxyflavanone, 5,7,4′-trimethoxyflavanone, 5-hydroxy-7,4′-dimethoxyflavone, and 5,7,4′-trimethoxyflavone) has been demonstrated for the first time. Conclusions This cocultivation system based on the phenylpropanoid-producing E. coli and SaOMT2-expressing S. venezuelae provides an efficient tool for producing scarce and potentially valuable multi-methylated phenylpropanoids and will enable further development of these compounds as pharmaceuticals and nutraceuticals.

Abstract
Microbial cell factories are extensively used for the biosynthesis of value-added chemicals, biopharmaceuticals, and biofuels. Microbial biosynthesis is also realistic for the production of heterologous molecules including complex natural products of plant and microbial origin. Glycosylation is a well-known post-modification method to engineer sugar-functionalized natural products. It is of particular interest to chemical biologists to increase chemical diversity of molecules. Employing the state-of-the-art systems and synthetic biology tools, a range of small to complex glycosylated natural products have been produced from microbes using a simple and sustainable fermentation approach. In this context, this review covers recent notable metabolic engineering approaches used for the biosynthesis of glycosylated plant and microbial polyketides in different microorganisms. This review article is broadly divided into two major parts. The first part is focused on the biosynthesis of glycosylated plant polyketides in prokaryotes and yeast cells, while the second part is focused on the generation of glycosylated microbial polyketides in actinomycetes.

Abstract
Anthracyclines, such as doxorubicin, are effective anticancer drugs composed of a tetracyclic polyketide aglycone and one or more deoxysugar moieties, which play a critical role in their biological activity. A facile one-pot combinatorial biosynthetic system was developed for the generation of a range of glycosylated derivatives of anthracyclines. Cocultivation of Streptomyces venezuelae mutants producing two anthracycline aglycones with eight different nucleotide deoxysugar-producing S. venezuelae mutants that coexpress a substrate-flexible glycosyltransferase led to the generation of 16 aklavinone or ε-rhodomycinone glycosides containing diverse deoxysugar moieties, seven of which are new. This demonstrates the potential of the one-pot combinatorial biosynthetic system based on cocultivation as a facile biological tool capable of combining diverse aglycones and deoxysugars to generate structurally diverse polyketides carrying engineered sugars for drug discovery and development.

Characterization and engineering of the biosynthesis gene cluster for antitumor macrolides PM100117 and PM100118 from a marine actinobacteria: generation of a novel improved derivative. Microb Cell Fact 2016; 15:44. [PMID: 26905289 PMCID: PMC4763440 DOI: 10.1186/s12934-016-0443-5] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2015] [Accepted: 02/11/2016] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND PM100117 and PM100118 are glycosylated polyketides with remarkable antitumor activity, which derive from the marine symbiotic actinobacteria Streptomyces caniferus GUA-06-05-006A. Structurally, PM100117 and PM100118 are composed of a macrocyclic lactone, three deoxysugar units and a naphthoquinone (NQ) chromophore that shows a clear structural similarity to menaquinone. RESULTS Whole-genome sequencing of S. caniferus GUA-06-05-006A has enabled the identification of PM100117 and PM100118 biosynthesis gene cluster, which has been characterized on the basis of bioinformatics and genetic engineering data. The product of four genes shows high identity to proteins involved in the biosynthesis of menaquinone via futalosine. Deletion of one of these genes led to a decay in PM100117 and PM100118 production, and to the accumulation of several derivatives lacking NQ. Likewise, five additional genes have been genetically characterized to be involved in the biosynthesis of this moiety. Moreover, the generation of a mutant in a gene coding for a putative cytochrome P450 has led to the production of PM100117 and PM100118 structural analogues showing an enhanced in vitro cytotoxic activity relative to the parental products. CONCLUSIONS Although a number of compounds structurally related to PM100117 and PM100118 has been discovered, this is, to our knowledge, the first insight reported into their biosynthesis. The structural resemblance of the NQ moiety to menaquinone, and the presence in the cluster of four putative menaquinone biosynthetic genes, suggests a connection between the biosynthesis pathways of both compounds. The availability of the PM100117 and PM100118 biosynthetic gene cluster will surely pave a way to the combinatorial engineering of more derivatives.

Abstract
Type I modular polyketide synthases are responsible for potent therapeutic compounds that include avermectin (antihelinthic), rapamycin (immunosuppressant), pikromycin (antibiotic), and erythromycin (antibiotic). However, compound access and biosynthetic manipulation are often complicated by properties of native production organisms, prompting an approach (termed heterologous biosynthesis) illustrated in this study through the reconstitution of the erythromycin pathway through Escherichia coli. Using this heterologous system, 16 tailoring pathways were introduced, systematically producing eight chiral pairs of deoxysugar substrates. Successful analog formation for each new pathway emphasizes the remarkable flexibility of downstream enzymes to accommodate molecular variation. Furthermore, analogs resulting from three of the pathways demonstrated bioactivity against an erythromycin-resistant Bacillus subtilis strain. The approach and results support a platform for continued molecular diversification of the tailoring components of this and other complex natural product pathways in a manner that mirrors the modular nature of the upstream megasynthases responsible for aglycone polyketide formation.

Abstract
Because of extraordinary structural diversity and broad biological activities, natural products have played a significant role in drug discovery. These therapeutically important secondary metabolites are assembled and modified by dedicated biosynthetic pathways in their host living organisms. Traditionally, chemists have attempted to synthesize natural product analogs that are important sources of new drugs. However, the extraordinary structural complexity of natural products sometimes makes it challenging for traditional chemical synthesis, which usually involves multiple steps, harsh conditions, toxic organic solvents, and byproduct wastes. In contrast, combinatorial biosynthesis exploits substrate promiscuity and employs engineered enzymes and pathways to produce novel “unnatural” natural products, substantially expanding the structural diversity of natural products with potential pharmaceutical value. Thus, combinatorial biosynthesis provides an environmentally friendly way to produce natural product analogs. Efficient expression of the combinatorial biosynthetic pathway in genetically tractable heterologous hosts can increase the titer of the compound, eventually resulting in less expensive drugs. In this review, we will discuss three major strategies for combinatorial biosynthesis: 1) precursor-directed biosynthesis; 2) enzyme-level modification, which includes swapping of the entire domains, modules and subunits, site-specific mutagenesis, and directed evolution; 3) pathway-level recombination. Recent examples of combinatorial biosynthesis employing these strategies will also be highlighted in this review.

Deoxysugar pathway interchange for erythromycin analogues heterologously produced through Escherichia coli. Metab Eng 2013; 20:92-100. [PMID: 24060454 DOI: 10.1016/j.ymben.2013.09.005] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2013] [Revised: 08/30/2013] [Accepted: 09/11/2013] [Indexed: 01/16/2023]
Abstract
The overall erythromycin biosynthetic pathway can be sub-divided into macrocyclic polyketide formation and polyketide tailoring to produce the final bioactive molecule. In this study, the native deoxysugar tailoring reactions were exchanged for the purpose of demonstrating the production of alternative final erythromycin compounds. Both the d-desosamine and l-mycarose deoxysugar pathways were replaced with the alternative d-mycaminose and d-olivose pathways to produce new erythromycin analogues through the Escherichia coli heterologous system. Both analogues exhibited bioactivity against multiple antibiotic-resistant Bacillus subtilis strains. Besides demonstrating an intrinsic flexibility for the biosynthetic system to accommodate alternative tailoring pathways, the results offer an initial attempt to leverage the E. coli platform for erythromycin analogue production.

Abstract
Glycosylation is one of the most important post-modification processes of small molecules and enables the parent molecule to have increased solubility, stability, and bioactivity. Enzyme-based glycosylation has achieved significant progress due to advances in protein engineering, DNA recombinant techniques, exploitation of biosynthetic gene clusters of natural products, and computer-based modeling programs. Our report summarizes glycosylation data that have been published within the past five years to provide an overall review of current progress. We also present the future trends and perspectives for glycosylation.
