Abstract
Antimicrobial resistance is one of the main global threats to human health in the 21st century due to the rapid appearance of bacterial resistance and the lack of novel bioactive compounds. Natural products, especially from Actinomycetes, remain the best source to refill the drug industry pipeline. Different strategies have been pursued to increase the chances of discovering new molecules, such as studying underexplored environments like arthropod symbionts, which represent a relevant reservoir for active metabolites. This review summarizes recent research on the identification of bioactive molecules produced by Actinomycetes associated with arthropods' microbiome. The metabolites have been categorized based on their structural properties and host, highlighting that multidisciplinary approaches will be the key to fully understanding this complex relationship.

Abstract
A genome mining approach was used to identify a hybrid tubercidin-nucleocidin biosynthetic gene cluster (BGC) in Streptomyces sp. AVP053U2. Analysis of culture extracts by liquid chromatography-mass spectrometry revealed the presence of a glucosylated tubercidin derivative. A gene, avpGT, was identified within the hybrid cluster that has homology to the glucosyltransferase that is responsible for 3'-O-β-glucosylation of the fluorinated natural product nucleocidin. AvpGT was heterologously expressed and purified from Escherichia coli for in vitro characterization. AvpGT is active toward UDP-glucose and UDP-galactose as glycosyl donors and several nucleosides as acceptors. Kinetic analysis revealed that AvpGT is most specific for UDP-glucose [kcat/KMapp = (1.1 ± 0.3) × 105 M-1·s-1] as the glycosyl donor and tubercidin [kcat/KMapp = (5.3 ± 1.8) × 104 M-1·s-1] as the glycosyl acceptor. NMR spectroscopic analysis revealed the product of this reaction to be 3'-O-β-glucopyranosyl tubercidin. A sequence analysis of AvpGT reveals a family of nucleoside-specific GTs, which may be used as markers of BGCs that produce glycosylated nucleosides.

Abstract
The nucleoside antibiotic toyocamycin (TM), which is produced by Streptomyces diastatochromogenes 1628, exhibits potent activity against a broad range of phytopathogenic fungi. TM was synthesized through a multi-step reaction, using guanosine triphosphate (GTP) as precursor. Based on a comparison of proteomics data from S. diastatochromogenes 1628 and rifamycin-resistant mutant 1628-T15 with high yield of TM, we determined that the differentially expressed protein X0NBV6 called ribose-phosphate pyrophosphokinase (RHP), which is a rate-limiting enzyme involved in the de novo biosynthesis of GTP, exhibits a higher expression level in mutant 1628-T15. In this study, to elucidate the relationships between RHP, GTP, and TM production, the gene rhp sd encoding RHP was cloned and overexpressed in S. diastatochromogenes strain 1628. The recombinant strain S. diastatochromogenes 1628-RHP exhibited better performance at the transcriptional level of the rhp sd gene, as well as RHP enzymatic activity, intracellular GTP concentration, and TM production, compared to S. diastatochromogenes 1628. Finally, the yield of TM produced by S. diastatochromogenes 1628-RHP (340.2 mg/L) was 133.3% higher than that produced by S. diastatochromogenes1628. Moreover, the transcriptional level of toy genes involved in TM biosynthesis was enhanced due to the overexpression of the rhp sd gene.

Abstract
Actinomycetes are prolific sources of bioactive molecules. Traditional workflows including bacterial isolation, fermentation, metabolite identification and structure elucidation have resulted in high rates of natural product rediscovery in recent years. Recent advancements in multi-omics techniques have uncovered cryptic gene clusters within the genomes of actinomycetes, potentially introducing vast resources for the investigation of bioactive molecules. While developments in culture techniques have allowed for the fermentation of difficult-to-culture actinomycetes, high-throughput metabolite screening has offered plenary tools to accelerate hits discovery. A variety of new bioactive molecules have been isolated from actinomycetes of unique environmental origins, such as endophytic and symbiotic actinomycetes. Synthetic biology and genome mining have also emerged as new frontiers for the discovery of bioactive molecules. This review covers the highlights of recent developments in actinomycete-derived natural product drug discovery.

Abstract
Covering period: up to 2019Water-soluble natural products constitute a relevant group of secondary metabolites notably known for presenting potent biological activities. Examples are aminoglycosides, β-lactam antibiotics, saponins of both terrestrial and marine origin, and marine toxins. Although extensively investigated in the past, particularly during the golden age of antibiotics, hydrophilic fractions have been less scrutinized during the last few decades. This review addresses the possible reasons on why water-soluble metabolites are now under investigated and describes approaches and strategies for the isolation of these natural compounds. It presents examples of several classes of hydrosoluble natural products and how they have been isolated. Novel stationary phases and chromatography techniques are also reviewed, providing a perspective towards a renaissance in the investigation of water-soluble natural products.

Abstract
LCMS-guided screening of a library of biosynthetically talented bacteria and fungi identified Streptomyces sp. MST- as a prolific producer of chlorinated metabolites. We isolated and characterised six new and nine reported compounds from MST-, belonging to three discrete classes - the depsipeptide svetamycins, the indolocarbazole borregomycins and the aromatic polyketide anthrabenzoxocinones. Following genome sequencing of MST-, we describe, for the first time, the svetamycin biosynthetic gene cluster (sve), its mosaic structure and its relationship to several distantly related gene clusters. Our analysis of the sve cluster suggested that the reported stereostructures of the svetamycins may be incorrect. This was confirmed by single-crystal X-ray diffraction analysis, allowing us to formally revise the absolute configurations of svetamycins A-G. We also show that the borregomycins and anthrabenzoxocinones are encoded by a single supercluster (bab) implicating superclusters as potential nucleation points for the evolution of biosynthetic gene clusters. These clusters highlight how individual enzymes and functional subclusters can be co-opted during the formation of biosynthetic gene clusters, providing a rare insight into the poorly understood mechanisms underpinning the evolution of chemical diversity.

Abstract
In the current scenario, the increasing prevalence of diverse microbial infections as well as emergence and re-emergence of viral epidemics with high morbidity and mortality rates are major public health threat. Despite the persistent production of antiviral drugs and vaccines in the global market, viruses still remain as one of the leading causes of deadly human diseases. Effective control of viral diseases, particularly Zika virus disease, Nipah virus disease, Severe acute respiratory syndrome, Coronavirus disease, Herpes simplex virus infection, Acquired immunodeficiency syndrome, and Ebola virus disease remain promising goal amidst the mutating viral strains. Current trends in the development of antiviral drugs focus solely on testing novel drugs or repurposing drugs against potential targets of the viruses. Compared to synthetic drugs, medicines from natural resources offer less side-effect to humans and are often cost-effective in the productivity approaches. This review intends not only to emphasize on the major viral disease outbreaks in the past few decades and but also explores the potentialities of natural substances as antiviral traits to combat viral pathogens. Here, we spotlighted a comprehensive overview of antiviral components present in varied natural sources, including plants, fungi, and microorganisms in order to identify potent antiviral agents for developing alternative therapy in future.

Abstract
The genus Streptomyces constitutes approximately 50% of all soil actinomycetes, playing a significant role in the soil microbial community through vital functions including nutrient cycling, production of bioactive metabolites, disease-suppression and plant growth promotion. Streptomyces produce many bioactive compounds and are prime targets for industrial and biotechnological applications. In addition to their agrobiological roles, some Streptomyces spp. can, however, be phytopathogenic, examples include, common scab of potato that causes economic losses worldwide. Currently used chemical control measures can have detrimental effect to environmental and human health as a result alternative methods to chemical disease control are being investigated. One alternative is the use of streptomycete specific phages to remove this pathogenic bacterium before it can cause the disease on potatoes. However, due to co-existence of non-common scab-causing species belonging to the genus Streptomyces, phage treatment is likely to affect a wide range of non-target streptomycete species including the beneficial ones in the soil. Therefore, before such treatment starts the host range of the phages within the targeted family of bacteria should be determined. In a study conducted using soil samples from a Tasmanian potato farm, streptomycetes were isolated and tested against streptomycete-specific phages. Their antifungal activity was also determined using multiple assays against selected phytopathogens. The four strongest antifungal activity-displaying isolates were further tested for their persistent antifungal activity using wheat and Fusarium solani in a pot trial. A second pot trial was also conducted to evaluate whether the beneficial streptomycetes were affected by streptophage treatment and whether their removal via the phage battery would cause opportunistic fungal infections to plants in soil. The streptomycetes prevented the reduction in wheat shoot weight caused by F. solani indicating their disease suppressive effect. However, when phages were added into the pots, the growth of wheat was detrimentally impacted. This finding might suggest that the reduced presence of antifungal streptomycetes via phage-induced lysis might encourage opportunistic fungal infections in plants.

Abstract
Antibiotic resistance poses an increasing threat to global health, and it is urgent to reverse the present trend by accelerating development of new natural product derived drugs. Nucleoside antibiotics, a valuable family of promising natural products with remarkable structural features and diverse biological activities, have played significant roles in healthcare and for plant protection. Understanding the biosynthesis of these intricate molecules has provided a foundation for bioengineering the microbial cell factory towards yield enhancement and structural diversification. In this review, we summarize the recent progresses in employing synthetic biology-based strategies to improve the production of target nucleoside antibiotics. Moreover, we delineate the advances on rationally accessing the chemical diversities of natural nucleoside antibiotics.

Abstract
The need for new antimicrobial therapies is evident, especially to reduce antimicrobial resistance and minimize deleterious effects on gut microbiota. However, although diverse studies discuss the adverse effects of broad-spectrum antibiotics on the microbiome ecology, targeted interventions that could solve this problem have often been overlooked. The impact of antibiotics on gut microbiota homeostasis is alarming, compromising its microbial community and leading to changes in host health. Recent studies have shown that these impacts can be transient or permanent, causing irreversible damage to gut microbiota. The responses to and changes in the gut microbial community arising from antibiotic treatment are related to its duration, the number of doses, antibiotic class, host age, genetic susceptibility, and lifestyle. In contrast, each individual's native microbiota can also affect the response to treatment as well as respond differently to antibiotic treatment. In this context, the current challenge is to promote the growth of potentially beneficial microorganisms and to reduce the proportion of microorganisms that cause dysbiosis, thus contributing to an improvement in the patient's health. An essential requirement for the development of novel antibiotics will be personalized medicinal strategies that recognize a patient's intestinal and biochemical individuality. Thus, this Review will address a new perspective on antimicrobial therapies through pathogen-selective antibiotics that minimize the impacts on human health due to changes in the gut microbiota from the use of antibiotics.

Abstract
The first total synthesis of the marine nucleoside Mycalisine B-a naturally occurring and structurally distinct 4,5-unsaturated 7-deazapurine nucleoside-has been accomplished in 10 linear steps with 27.5% overall yield from commercially available 1,2,3,5-tetra-O-acetyl-ribose and tetracyanoethylene. Key steps of the approach include: (1) I2 catalyzed acetonide formation from 1,2,3,5-tetra-O-acetylribose and acetone at large scale; (2) Vorbrüggen glycosylation using N4-benzoyl-5-cyano-6-bromo-7H-pyrrolo[2,3-d]pyrimidine as a nucleobase to avoid formation of N-3 isomer; (3) mild and scalable reaction conditions.

Coordinated Biosynthesis of the Purine Nucleoside Antibiotics Aristeromycin and Coformycin in Actinomycetes. Appl Environ Microbiol 2018; 84:AEM.01860-18.

Abstract
Purine nucleoside antibiotic pairs, concomitantly produced by a single strain, are an important group of microbial natural products. Here, we report a target-directed genome mining approach to elucidate the biosynthesis of the purine nucleoside antibiotic pair aristeromycin (ARM) and coformycin (COF) in Micromonospora haikouensis DSM 45626 (a new producer for ARM and COF) and Streptomyces citricolor NBRC 13005 (a new COF producer). We also provide biochemical data that MacI and MacT function as unusual phosphorylases, catalyzing an irreversible reaction for the tailoring assembly of neplanocin A (NEP-A) and ARM. Moreover, we demonstrate that MacQ is shown to be an adenosine-specific deaminase, likely relieving the potential "excess adenosine" for producing cells. Finally, we report that MacR, an annotated IMP dehydrogenase, is actually an NADPH-dependent GMP reductase, which potentially plays a salvage role for the efficient supply of the precursor pool. Hence, these findings illustrate a fine-tuned pathway for the biosynthesis of ARM and also open the way for the rational search for purine antibiotic pairs.IMPORTANCE ARM and COF are well known for their prominent biological activities and unusual chemical structures; however, the logic of their biosynthesis has long been poorly understood. Actually, the new insights into the ARM and COF pathway will not only enrich the biochemical repertoire for interesting enzymatic reactions but may also lay a solid foundation for the combinatorial biosynthesis of this group of antibiotics via a target-directed genome mining strategy.

An ATP-Dependent Ligase with Substrate Flexibility Involved in Assembly of the Peptidyl Nucleoside Antibiotic Polyoxin. Appl Environ Microbiol 2018; 84:AEM.00501-18. [PMID: 29703734 DOI: 10.1128/aem.00501-18] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2018] [Accepted: 04/19/2018] [Indexed: 11/20/2022] Open
Abstract
Polyoxin (POL) is an unusual peptidyl nucleoside antibiotic, in which the peptidyl moiety and nucleoside skeleton are linked by an amide bond. However, their biosynthesis remains poorly understood. Here, we report the deciphering of PolG as an ATP-dependent ligase responsible for the assembly of POL. A polG mutant is capable of accumulating multiple intermediates, including the peptidyl moiety (carbamoylpolyoxamic acid [CPOAA]) and the nucleoside skeletons (POL-C and the previously overlooked thymine POL-C). We further demonstrate that PolG employs an ATP-dependent mechanism for amide bond formation and that the generation of the hybrid nucleoside antibiotic POL-N is also governed by PolG. Finally, we determined that the deduced ATP-binding sites are functionally essential for PolG and that they are highly conserved in a number of related ATP-dependent ligases. These insights have allowed us to propose a catalytic mechanism for the assembly of peptidyl nucleoside antibiotic via an acyl-phosphate intermediate and have opened the way for the combinatorial biosynthesis/pathway engineering of this group of nucleoside antibiotics.IMPORTANCE POL is well known for its remarkable antifungal bioactivities and unusual structural features. Actually, elucidation of the POL assembly logic not only provides the enzymatic basis for further biosynthetic understanding of related peptidyl nucleoside antibiotics but also contributes to the rational generation of more hybrid nucleoside antibiotics via synthetic biology strategy.

Abstract
The Immucillins are chemically stable analogues that mimic the ribocation and leaving-group features of N-ribosyltransferase transition states. Infectious disease agents often rely on ribosyltransferase chemistry in pathways involving precursor synthesis for nucleic acids, salvage of nucleic acid precursors, or synthetic pathways with nucleoside intermediates. Here, we review three infectious agents and the use of the Immucillins to taget enzymes essential to the parasites. First, DADMe-Immucillin-G is a purine nucleoside phosphorylase (PNP) inhibitor that blocks purine salvage and shows clinical potential for treatment for the malaria parasite Plasmodium falciparum, a purine auxotroph requiring hypoxanthine for purine nucleotide synthesis. Inhibition of the PNPs in the host and in parasite cells leads to apurinic starvation and death. Second, Helicobacter pylori, a causative agent of human ulcers, synthesizes menaquinone, an essential electron transfer agent, in a pathway requiring aminofutalosine nucleoside hydrolysis. Inhibitors of the H. pylori methylthioadenosine nucleosidase (MTAN) are powerful antibiotics for this organism. Synthesis of menaquinone by the aminofutalosine pathway does not occur in most bacteria populating the human gut microbiome. Thus, MTAN inhibitors provide high-specificity antibiotics for H. pylori and are not expected to disrupt the normal gut bacterial flora. Third, Immucillin-A was designed as a transition state analogue of the atypical PNP from Trichomonas vaginalis. In antiviral screens, Immucillin-A was shown to act as a prodrug. It is active against filoviruses and flaviviruses. In virus-infected cells, Immucillin-A is converted to the triphosphate, is incorporated into the viral transcript, and functions as an atypical chain-terminator for RNA-dependent RNA polymerases. Immucillin-A has entered clinical trials for use as an antiviral. We also summarize other Immucillins that have been characterized in successful clinical trials for T-cell lymphoma and gout. The human trials support the potential development of the Immucillins in infectious diseases.
