Abstract
We have created a novel synthetic biology expression system allowing easy refactoring of biosynthetic gene clusters (BGCs) as monocistronic transcriptional units. The system is based on a set of plasmids containing a strong kasOp* promoter, RBS and terminators. It allows the cloning of biosynthetic genes into transcriptional units kasOp*-gene(s)-terminator flanked by several rare restriction cloning sites that can be sequentially combined into the artificial BGC in three compatible Streptomyces integration vectors. They allow a simultaneous integration of these BGCs at three different attB sites in the Streptomyces chromosome. The system was validated with biosynthetic genes from two known BGCs for aromatic polyketides landomycin and mithramycin.

Abstract
Streptomyces spp. are "nature's antibiotic factories" that produce valuable bioactive metabolites, such as the cytotoxic anthracycline polyketides. While the anthracyclines have hundreds of natural and chemically synthesized analogues, much of the chemical diversity stems from enzymatic modifications to the saccharide chains and, to a lesser extent, from alterations to the core scaffold. Previous work has resulted in the generation of a BioBricks synthetic biology toolbox in Streptomyces coelicolor M1152ΔmatAB that could produce aklavinone, 9-epi-aklavinone, auramycinone, and nogalamycinone. In this work, we extended the platform to generate oxidatively modified analogues via two crucial strategies. (i) We swapped the ketoreductase and first-ring cyclase enzymes for the aromatase cyclase from the mithramycin biosynthetic pathway in our polyketide synthase (PKS) cassettes to generate 2-hydroxylated analogues. (ii) Next, we engineered several multioxygenase cassettes to catalyze 11-hydroxylation, 1-hydroxylation, 10-hydroxylation, 10-decarboxylation, and 4-hydroxyl regioisomerization. We also developed improved plasmid vectors and S. coelicolor M1152ΔmatAB expression hosts to produce anthracyclinones. This work sets the stage for the combinatorial biosynthesis of bespoke anthracyclines using recombinant Streptomyces spp. hosts.

Abstract
Structural and functional studies of the carminomycin 4-O-methyltransferase DnrK are described, with an emphasis on interrogating the acceptor substrate scope of DnrK. Specifically, the evaluation of 100 structurally and functionally diverse natural products and natural product mimetics revealed an array of pharmacophores as productive DnrK substrates. Representative newly identified DnrK substrates from this study included anthracyclines, angucyclines, anthraquinone-fused enediynes, flavonoids, pyranonaphthoquinones, and polyketides. The ligand-bound structure of DnrK bound to a non-native fluorescent hydroxycoumarin acceptor, 4-methylumbelliferone, along with corresponding DnrK kinetic parameters for 4-methylumbelliferone and native acceptor carminomycin are also reported for the first time. The demonstrated unique permissivity of DnrK highlights the potential for DnrK as a new tool in future biocatalytic and/or strain engineering applications. In addition, the comparative bioactivity assessment (cancer cell line cytotoxicity, 4E-BP1 phosphorylation, and axolotl embryo tail regeneration) of a select set of DnrK substrates/products highlights the ability of anthracycline 4-O-methylation to dictate diverse functional outcomes.

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
Tetracenomycins and elloramycins are polyketide natural products produced by several actinomycetes that exhibit antibacterial and anticancer activities. They inhibit ribosomal translation by binding in the polypeptide exit channel of the large ribosomal subunit. The tetracenomycins and elloramycins are typified by a shared oxidatively modified linear decaketide core, yet they are distinguished by the extent of O-methylation and the presence of a 2',3',4'-tri-O-methyl-α-l-rhamnose appended at the 8-position of elloramycin. The transfer of the TDP-l-rhamnose donor to the 8-demethyl-tetracenomycin C aglycone acceptor is catalyzed by the promiscuous glycosyltransferase ElmGT. ElmGT exhibits remarkable flexibility toward transfer of many TDP-deoxysugar substrates to 8-demethyltetracenomycin C, including TDP-2,6-dideoxysugars, TDP-2,3,6-trideoxysugars, and methyl-branched deoxysugars in both d- and l-configurations. Previously, we developed an improved host, Streptomyces coelicolor M1146::cos16F4iE, which is a stable integrant harboring the required genes for 8-demethyltetracenomycin C biosynthesis and expression of ElmGT. In this work, we developed BioBricks gene cassettes for the metabolic engineering of deoxysugar biosynthesis in Streptomyces spp. As a proof of concept, we used the BioBricks expression platform to engineer biosynthesis for d-configured TDP-deoxysugars, including known compounds 8-O-d-glucosyl-tetracenomycin C, 8-O-d-olivosyl-tetracenomycin C, 8-O-d-mycarosyl-tetracenomycin C, and 8-O-d-digitoxosyl-tetracenomycin C. In addition, we generated four new tetracenomycins including one modified with a ketosugar, 8-O-4'-keto-d-digitoxosyl-tetracenomycin C, and three modified with 6-deoxysugars, including 8-O-d-fucosyl-tetracenomycin C, 8-O-d-allosyl-tetracenomycin C, and 8-O-d-quinovosyl-tetracenomycin C. Our work demonstrates the feasibility of BioBricks cloning, with the ability to recycle intermediate constructs, for the rapid assembly of diverse carbohydrate pathways and glycodiversification of a variety of natural products.

Abstract
Actinomycetes produce a variety of clinically indispensable molecules, such as antineoplastic anthracyclines. However, the actinomycetes are hindered in their further development as genetically engineered hosts for the synthesis of new anthracycline analogues due to their slow growth kinetics associated with their mycelial life cycle and the lack of a comprehensive genetic toolbox for combinatorial biosynthesis. In this report, we tackled both issues via the development of the BIOPOLYMER (BIOBricks POLYketide Metabolic EngineeRing) toolbox: a comprehensive synthetic biology toolbox consisting of engineered strains, promoters, vectors, and biosynthetic genes for the synthesis of anthracyclinones. An improved derivative of the production host Streptomyces coelicolor M1152 was created by deleting the matAB gene cluster that specifies extracellular poly-β-1,6-N-acetylglucosamine (PNAG). This resulted in a loss of mycelial aggregation, with improved biomass accumulation and anthracyclinone production. We then leveraged BIOPOLYMER to engineer four distinct anthracyclinone pathways, identifying optimal combinations of promoters, genes, and vectors to produce aklavinone, 9-epi-aklavinone, auramycinone, and nogalamycinone at titers between 15-20 mg/L. Optimization of nogalamycinone production strains resulted in titers of 103 mg/L. We structurally characterized six anthracyclinone products from fermentations, including new compounds 9,10-seco-7-deoxy-nogalamycinone and 4-O-β-d-glucosyl-nogalamycinone. Lastly, we tested the antiproliferative activity of the anthracyclinones in a mammalian cancer cell viability assay, in which nogalamycinone, auramycinone, and aklavinone exhibited moderate cytotoxicity against several cancer cell lines. We envision that BIOPOLYMER will serve as a foundational platform technology for the synthesis of designer anthracycline analogues.
