Matrix-assisted laser desorption/ionization imaging high-resolution mass spectrometry (MALDI-imaging-HRMS) is an important technique for visualizing the spatial distribution of compounds directly on the surface of organisms such as microorganisms, insects, plants, animals, and human tissues. However, MALDI-imaging-HRMS and the stable isotope labeling approach have never been combined for the Cited by: 1.
Streptomyces, the largest genus of actinobacteria, are famous for their large variety of natural products produced ribosomally, by PKS, NRPS or other pathways. For example, Streptomyces coelicolor is a Gram-positive bacterium that contains 30 biosynthetic secondary metabolite clusters that produce natural products, including actinorhodin Cited by: From dormant to germinating spores of Streptomyces coelicolor A3(2): new perspectives from the crp null mutant.

F1: Production of pigmented secondary metabolites by Streptomyces colonies. (a) Typical colonial morphologies of Streptomyces isolated from the soil. Colonies often excrete colored pigments, providing a visual recording of secondary metabolite biosynthesis.
Introduction. The majority of antibiotics used in medicine, veterinary practice, and agriculture originate from Streptomyces bacteria. Genomic analysis has shown that any one strain has the potential to make tens of such secondary metabolites, and metagenomic analysis has revealed vast numbers of relevant biosynthetic gene sets 1, organisms are therefore being studied ever Cited by: Regulation of secondary metabolism in Streptomyces Article Literature Review in Current Opinion in Microbiology 8(2) May with Reads How we measure 'reads'Author: Mervyn Bibb.

Streptomyces is a genus of Gram-positive bacteria that grows in various environments, and its shape resembles filamentous fungi. The morphological differentiation of Streptomyces involves the formation of a layer of hyphae that can differentiate into a chain of spores. The most interesting property of Streptomyces is the ability to produce bioactive secondary metabolites, such as antifungals Cited by: This chapter discusses the genetics of antibiotic production in Streptomyces coelicolor (olor) A3 (2), a model streptomycet.A primary genetic resource for any organism is a genomic map that can lead to the construction of a set of ordered clones that includes the whole genome in manageable fragments and, eventually, to a complete DNA by: Genetic mapping of the chromosome of Streptomyces coelicolor A3(2) began with the analysis of haploid recombinants selected from matings.
A physical map of the S. coelicolor chromosome has recently been constructed, using pulsed-field gel electrophoresis of AseI and DraI fragments. The genetic map was found to be reasonably congruent with the physical map over the well-marked by: 2.
Specialized metabolites are of great interest due to their possible industrial and clinical applications. The increasing number of antimicrobial resistant infectious agents is a major health threat and therefore, the discovery of chemical diversity and new antimicrobials is crucial.
Extensive genomic data from Streptomyces spp. confirm their production potential and great by: 8. Abstract. Of the over known antibiotics, more than are produced by Actinomycetes. In fact, over 85% of the species which produce antibiotics are Actinomycetes, including Nocardia, Streptosporangium, Micromonospora, Actinoplanes, and Streptomyces [23,32], Table 1 shows how these are divided [3,26].Cited by: 1.
Here we report functional characterization of the Streptomyces coelicolor M gene SCO, which encodes a GntR-like regulator of the FadR subfamily.
Bioinformatic analysis suggested that SCO is part of putative operon (gnt) involved in gluconate metabolism. Combining the results of SCO knockout, transcriptional analysis of gnt operon, and Sco protein-DNA electromobility Cited by: 6.

Exhibiting various bioactivities, they provide valuable approved drugs in clinical use. Most microorganisms are still untapped in terms of their capacity to produce secondary metabolites, since only a small fraction can be cultured in the by: Currently, Dr. Lee's research focuses on the study of novel bacteria identification and bio-prospecting of secondary metabolites with antimicrobial and anticancer properties.
