Discovery, characterization, and engineering of an advantageous Streptomyces host for heterologous expression of natural product biosynthetic gene clusters. Microb Cell Fact 2024; 23:149. [PMID: 38790014 PMCID: PMC11127301 DOI: 10.1186/s12934-024-02416-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Accepted: 05/05/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND Streptomyces is renowned for its robust biosynthetic capacity in producing medically relevant natural products. However, the majority of natural products biosynthetic gene clusters (BGCs) either yield low amounts of natural products or remain cryptic under standard laboratory conditions. Various heterologous production hosts have been engineered to address these challenges, and yet the successful activation of BGCs has still been limited. In our search for a valuable addition to the heterologous host panel, we identified the strain Streptomyces sp. A4420, which exhibited rapid initial growth and a high metabolic capacity, prompting further exploration of its potential. RESULTS We engineered a polyketide-focused chassis strain based on Streptomyces sp. A4420 (CH strain) by deleting 9 native polyketide BGCs. The resulting metabolically simplified organism exhibited consistent sporulation and growth, surpassing the performance of most existing Streptomyces based chassis strains in standard liquid growth media. Four distinct polyketide BGCs were chosen and expressed in various heterologous hosts, including the Streptomyces sp. A4420 wild-type and CH strains, alongside Streptomyces coelicolor M1152, Streptomyces lividans TK24, Streptomyces albus J1074, and Streptomyces venezuelae NRRL B-65442. Remarkably, only the Streptomyces sp. A4420 CH strain demonstrated the capability to produce all metabolites under every condition outperforming its parental strain and other tested organisms. To enhance visualization and comparison of the tested strains, we developed a matrix-like analysis involving 15 parameters. This comprehensive analysis unequivocally illustrated the significant potential of the new strain to become a popular heterologous host. CONCLUSION Our engineered Streptomyces sp. A4420 CH strain exhibits promising attributes for the heterologous expression of natural products with a focus on polyketides, offering an alternative choice in the arsenal of heterologous production strains. As genomics and cloning strategies progress, establishment of a diverse panel of heterologous production hosts will be crucial for expediting the discovery and production of medically relevant natural products derived from Streptomyces.

Abstract
Coal and sillimanite mining sites present unique ecological niches favoring the growth of actinobacteria, a group of Gram-positive bacteria known for producing a wide array of bioactive compounds. Isolating these bacteria from such environments could unveil novel compounds with potential biotechnological applications. This study involved the isolation of actinobacteria from two mining sites in Meghalaya, India. The dominant genera from both sites were Streptomyces, Amycolatopsis, Nocardia, and Streptosporangium. Metabolic pathway prediction from 16S rRNA gene revealed several pathways beneficial for plant growth. Exploration of biosynthetic genes indicated a prevalence of the type-II polyketide synthase gene. Sequencing the ketosynthase-alpha domain of the gene led to predictions of various bioactive secondary metabolites. Around 44% of the isolates demonstrated antimicrobial properties, with some also displaying plant growth-promoting traits. Amycolatopsis SD-15 exhibited promising results in planta when tested on tomato plants. These findings highlight the potential of actinobacteria from Meghalaya's mining sites across medical, agricultural, and industrial domains.

Abstract
Glycosylation is common among the synthesis of natural product and imparts the bioactivity for natural product. As for granaticin, a natural product with great bioactivity, glycosylation is an unusual sugar attachment and remains enigmatic. Orf14 in the gra cluster is the predicted glycosyltransferase but without being identified. Recently, we isolated and identified a novel granaticin producer Streptomyces vilmorinianum YP1. Orf14 gene in gra cluster of YP1 is knocked out and complemented. The instrumental analysis of the blue product synthesized by orf14-deficient mutant exhibits the none-granaticin detection and deglycosylated intermediates accumulation. The bioactivity and stability test suggests the weaker or none antibacterial activity and cytotoxicity of this blue product with greater ultraviolet stability and thermostability than granaticin and derivatives produced by YP1. All the result indicates that orf14 encodes glycosyltransferase and glycosylation played an important role in the bioactivity of granaticin. Meanwhile, the blue pigment, deglycosylated intermediates, has favorable processing characteristics. Our finding supplies the function of orf14 and glycosylation, but also indicates a promising candidate of edible blue pigment applicated in food industry.

Abstract
C-Glycosylation in the biosynthesis of bioactive natural products is quite unique, which has not been studied well. Medermycin, as an antitumor agent in the family of pyranonaphthoquinone antibiotics, is featured with unique C-glycosylation. Here, a new C-glycosyltransferase (C-GT) Med-8 was identified to be essential for the biosynthesis of medermycin, as the first example of C-GT to recognize a rare deoxyaminosugar (angolosamine). med-8 and six genes (med-14, -15, -16, -17, -18, and -20 located in the medermycin biosynthetic gene cluster) predicted for the biosynthesis of angolosamine were proved to be functional and sufficient for C-glycosylation. A C-glycosylation cassette composed of these seven genes could convert a proposed substrate into a C-glycosylated product. In conclusion, these genes involved in the C-glycosylation of medermycin were functionally identified and biosynthetically engineered, and they provided the possibility of producing new C-glycosylated compounds.

A single-domain small protein Med-ORF10 regulates the production of antitumour agent medermycin in Streptomyces. Microb Biotechnol 2021; 14:1918-1930. [PMID: 34139068 PMCID: PMC8449675 DOI: 10.1111/1751-7915.13834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 04/19/2021] [Accepted: 05/03/2021] [Indexed: 11/28/2022] Open
Abstract
Med-ORF10, a single-domain protein with unknown function encoded by a gene located in a gene cluster responsible for the biosynthesis of a novel antitumour antibiotic medermycin, shares high homology to a group of small proteins widely distributed in many aromatic polyketide antibiotic pathways. This group of proteins contain a nuclear transport factor-2 (NTF-2) domain and appear to undergo an evolutionary divergence in their functions. Gene knockout and interspecies complementation suggested that Med-ORF10 plays a regulatory role in medermycin biosynthetic pathway. Overexpression of med-ORF10 in its wild-type strain led to significant increase of medermycin production. It was also shown by qRT-PCR and Western blot that Med-ORF10 controls the expression of genes encoding tailoring enzymes involved in medermycin biosynthesis. Transcriptome analysis and qRT-PCR revealed that Med-ORF10 has pleiotropic effects on more targets. However, there is no similar conserved domain available in Med-ORF10 compared to those of mechanistically known regulatory proteins; meanwhile, no direct interaction between Med-ORF10 and its target promoter DNA was detected via gel shift assay. All these studies suggest that Med-ORF10 regulates medermycin biosynthesis probably via an indirect mode.

Pleiotropic effects of ActVI-ORFA as an unusual regulatory factor identified in the biosynthetic pathway of actinorhodin in Streptomyces coelicolor. Microbiol Res 2021; 250:126792.

Abstract
Regulatory networks play critical roles in controlling the the biosynthesis of natural products in Streptomyces. ActVI-ORFA, a regulatory factor encoded by the actinorhodin biosynthetic gene cluster (act cluster), positively controls the production of actinorhodin (ACT) in Streptomyces coelicolor, although its regulatory mechanism remains obscure. This study aimed to identify the regulatory targets of ActVI-ORFA. Deletion of ActVI-ORFA caused the differential expression of hundreds of proteins, as determined by two-dimensional electrophoresis and peptide mass fingerprinting analysis. qRT-PCR analysis of some genes encoding these differentially expressed proteins, including act genes and non-act genes, confirmed that ActVI-ORFA could control their transcriptional levels. In an electrophoretic mobility shift assay with a promoter region of a target gene located in the act cluster, no binding was detected, consistent with the lack of a recognizable DNA-binding domain in ActVI-ORFA. Overall, our findings suggest that ActVI-ORFA is a pleiotropic regulatory factor that controls multiple physiological pathways, including secondary metabolite production, probably via an indirect mode.

Abstract
Marine actinobacteria are potential producers of various secondary metabolites with diverse bioactivities. Among various bioactive compounds, anti-complement agents have received great interest for drug discovery to treat numerous diseases caused by inappropriate activation of the human complement system. However, marine streptomycetes producing anti-complement agents are still poorly explored. In this study, a marine-derived strain Streptomyces sp. DUT11 showing superior anti-complement activity was focused, and its genome sequence was analyzed. Gene clusters showing high similarities to that of tunicamycin and nonactin were identified, and their corresponding metabolites were also detected. Subsequently, tunicamycin I, V, and VII were isolated from Streptomyces sp. DUT11. Anti-complement assay showed that tunicamycin I, V, VII inhibited complement activation through the classic pathway, whereas no anti-complement activity of nonactin was detected. This is the first time that tunicamycins are reported to have such activity. In addition, genome analysis indicates that Streptomyces sp. DUT11 has the potential to produce novel lassopeptides and lantibiotics. These results suggest that marine Streptomyces are rich sources of anti-complement agents for drug discovery.

Heterocycles are abundant structural elements of natural products from all classes and they often contribute significantly to their biological activity. Progress in recent years has led to a much better understanding of their biosynthesis. In this context, plenty of novel enzymology has been discovered, suggesting that these pathways are an attractive target for future studies.
