[Ab] Resumo:Streptomyces rimosus can produce antibacterial and antifungal antibiotics, which have important applications in medicine and agriculture. Seventy-nine microbial strains were employed to assay interaction between S. rimosus MY02 and different fungi, actinomyces, and bacteria when confront cultured on solid media. The results showed that the presence of a microorganism might affect the activity of another one. When S. rimosus MY02 confront cultured with other microorganisms, the inductive effect might be positive or negative. In this study, fungi showed to be effective elicitors, with a highest inductivity rate of 90.1%, and all of fungi showed positive induction behavior. Followed by bacteria with 59.6% of the tested bacterial strains showing positive inductivity, and the highest inductivity was 54.9%. Only six actinomyces (counting for 40% of the tested actinomyces strains) showed positive inductivity, and the highest induction rate of the strain NK413 was 34.1%. We also found that growth of most of bacteria or actinomyces which showed negative inductivity were similar or better than that of the strain MY02. However, the growth status of the strains was not positive related to inducing ability directly.

[Ab] Resumo:As microbial genome sequencing becomes more widespread, the capacity of microorganisms to produce an immense number of metabolites has come into better view. Utilizing a metabolite/gene cluster correlation platform, the biosynthetic origins of a new family of natural products, the rimosamides, were discovered. The rimosamides were identified in Streptomyces rimosus and associated with their NRPS/PKS-type gene cluster based upon their high frequency of co-occurrence across 179 strains of actinobacteria. This also led to the discovery of the related detoxin gene cluster. The core of each of these families of natural products contains a depsipeptide bond at the point of bifurcation in their unusual branched structures, the origins of which are definitively assigned to nonlinear biosynthetic pathways via heterologous expression in Streptomyces lividans. The rimosamides were found to antagonize the antibiotic activity of blasticidin S against Bacillus cereus.

[Ab] Resumo:Aminoglycoside phosphotransferases represent a broad class of enzymes that promote bacterial resistance to aminoglycoside antibiotics via the phosphorylation of hydroxyl groups in the latter. Here we report the spatial structure of the 3'-aminoglycoside phosphotransferase of novel VIII class (AphVIII) solved by X-ray diffraction method with a resolution of 2.15 Å. Deep analysis of APHVIII structure and its comparison with known structures of aminoglycoside phosphotransferases of various types reveals that AphVIII has a typical two-domain fold and, however, possesses some unique characteristics that distinguish the enzyme from its known homologues. The most important difference is the presence of the activation loop with unique Ser146 residue. We demonstrate that in the apo-state of the enzyme the activation loop does not interact with other parts of the enzyme and seems to adopt catalytically competent state only after substrate binding.

[Ab] Resumo:Actinomycetes have received considerable attention as biocontrol agents against fungal plant pathogens and as plant growth promoters. In this study, a total of 320 actinomycetes were isolated from various habitats in China. Among which, 77 strains have been identified as antagonistic activities against Fusarium oxysporum f. sp. cucumerinum which usually caused fusarium wilt of cucumber. Of these, isolate actinomycete M527 not only displayed broad-spectrum antifungal activity but also showed the strongest antagonistic activity against the spore germination of F. oxysporum f. sp. cucumerinum. In pot experiments, the results indicated that isolate M527 could promote the shoot growth and prevent the development of the disease on cucumber caused by F. oxysporum f. sp. cucumerinum. The control efficacy against seedling fusarium wilt of cucumber after M527 fermentation broth root-irrigation was up to 72.1% as compared to control. Based on 16S rDNA sequence analysis, the isolate M527 was identified as Streptomyces rimosus.

[Ti] Título:Identification of a cluster-situated activator of oxytetracycline biosynthesis and manipulation of its expression for improved oxytetracycline production in Streptomyces rimosus.

[Ab] Resumo:BACKGROUND: Oxytetracycline (OTC) is a broad-spectrum antibiotic commercially produced by Streptomyces rimosus. Despite its importance, little is known about the regulation of OTC biosynthesis, which hampered any effort to improve OTC production via engineering regulatory genes. RESULTS: A gene encoding a Streptomyces antibiotic regulatory protein (SARP) was discovered immediately adjacent to the otrB gene of oxy cluster in S. rimosus and designated otcR. Deletion and complementation of otcR abolished or restored OTC production, respectively, indicating that otcR encodes an essential activator of OTC biosynthesis. Then, the predicted consensus SARP-binding sequences were extracted from the promoter regions of oxy cluster. Transcriptional analysis in a heterologous GFP reporter system demonstrated that OtcR directly activated the transcription of five oxy promoters in E. coli, further mutational analysis of a SARP-binding sequence of oxyI promoter proved that OtcR directly interacted with the consensus repeats. Therefore, otcR was chosen as an engineering target, OTC production was significantly increased by overexpression of otcR as tandem copies each under the control of strong SF14 promoter. CONCLUSIONS: A SARP activator, OtcR, was identified in oxy cluster of S. rimosus; it was shown to directly activate five promoters from oxy cluster. Overexpression of otcR at an appropriate level dramatically increased OTC production by 6.49 times compared to the parental strain, thus demonstrating the great potential of manipulating OtcR to improve the yield of OTC production.

[Ab] Resumo:The aim of this study is to develop a synthetic medium suitable for 13C metabolic flux analysis (13C-MFA) of Streptomyces rimosus. The cell growth rate and oxytetracycline production by S. rimosus M4018 were compared when M4018 cells were growth on the optimized chemically defined media with organic nitrogen sources or inorganic nitrogen sources. First, a synthetic medium contained KNO3 as the main nitrogen source was screened, then optimized by a response surface method. Using this new medium, the oxytetracycline yield was increased from 75.2 to 145.6 mg/L. Furthermore, based on the 13C-MFA, we identified that Entner-Doudoroff pathway does not exist in S. rimosus cells cultured in a chemically defined medium with feed of 100% 1-13C labeled glucose. This study is helpful for subsequent 13C-MFA application of S. rimosus.

[Ti] Título:Diversity of the ectoines biosynthesis genes in the salt tolerant Streptomyces and evidence for inductive effect of ectoines on their accumulation.

[Ab] Resumo:Streptomyces commonly produce ectoines as compatible solutes to prevent osmotic stresses. Fine structure of the genes producing ectoine (ectC) and hydroxyectoine (ectD) enzymes in Streptomyces rimosus C-2012 as a slightly halophilic bacterium is reported in this study. Deduced amino acid sequences of ectC and ectD genes from strain C-2012 and some other related species were compared and 72-90% and 13-81% identities were detected for ectC and ectD, respectively. High similarity of ectC between closely or distantly related Streptomyces to the strain C-2012 may indicate horizontal transfer of this gene. However, phylogenetic relationships of ectD were correlated with phylogenetic affiliation of the strains. It suggests that the ability of Streptomyces to produce hydroxyectoine has been the result of a vertical transfer event. HPLC analysis showed that strain C-2012 was able to produce ectoine and hydroxyectoine both in the presence and absence of external salinity (up to 0.45 M NaCl). Accordingly, reverse transcription quantitative PCR (RT-qPCR) showed that ectABCD operon in this strain is positively affected by salt. Also, inductive effect of the salt was increased when it was applied with 1 mM of ectoines. Transcription level of ectC was increased 2.7- and 2.9-fold in the medium supplied with salt and ectoine and salt and hydroxyectoine, respectively. The effect of salinity with or without ectoines was more on ectD transcription level than that of ectC. In S. rimosus under salt stress, ectoine and hydroxyectoine biosynthesis primarily depends on the stimulation of ectABCD operon transcription. However, drastic accumulation of ectoine and hydroxyectoine without increase in ectC and ectD transcripts was observed in the medium supplied with salt and ectoines and that suggest there might be additional posttranscriptional level of control. Increases in ratio of some intracellular free amino acids in salt stressed to unstressed conditions were observed in cells grown with ectoines. Our results suggest the possibility of a supplementary role of ectoines to improve structure and function of the cells in stressful environments as well as their important role as osmoprotectants.

[Ab] Resumo:The transcriptional repressor Rex plays key roles in modulating respiratory gene expression. It senses the redox poise of the NAD(H) pool. Rex from Streptomyces rimosus (Sr-Rex) is a newly identified protein. Its structure and complex with substrates are not determined yet. In this study, the three-dimensional (3D) structural models of Sr-Rex dimer and its complex with cofactors were constructed by homology modeling. The stability of the constructed Sr-Rex models and the detailed interactions between Sr-Rex and cofactors were further investigated by molecular dynamics simulations. The results demonstrated that the conformation of Sr-Rex changed a lot when binding with the reduced NADH or oxidized NAD(+). Once binding with NADH, the Sr-Rex dimer displayed an opener conformation, which would weaken the interaction of Sr-Rex with Rex operator DNA (ROP). Key residues responsible for the binding were then identified. The computational results were consistent with experimental results, and hence provided insights into the molecular mechanism of Sr-Rex binding with ROP and NADH/NAD(+), which might be helpful for the development of biosensor.
