Deutsche Sammlung Von Mikroorganismen Und Zellkulturen
The Leibniz Institute DSMZ - German Collection of Microorganisms and Cell Cultures GmbH (German: ''Leibniz-Institut DSMZ-Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH''), located in Braunschweig, is a research infrastructure in the Leibniz Association. Also the DSMZ is the world's most diverse collection of bioresources (status 2021: 75,000 bioresources). These include microorganisms (including more than 32,000 bacterial strains, 690 archaeal strains, 7,000 strains of yeasts and fungi) as well as more than 840 human and animal cell cultures, over 1. 500 plant viruses, over 940 bacteriophages, and 250 plasmids (status 2021). Since 2010, the scientific director of the Leibniz Institute DSMZ has been Jörg Overmann, a microbiologist with a PhD. He holds a professorship in microbiology at the Technical University of Braunschweig. Since August 2018, he has led the institute in a dual leadership with Bettina Fischer as administrative director.

Streptomyces
''Streptomyces'' is the largest genus of Actinomycetota and the type genus of the family Streptomycetaceae. Over 500 species of ''Streptomyces'' bacteria have been described. As with the other Actinomycetota, streptomycetes are gram-positive, and have genomes with high GC content. Found predominantly in soil and decaying vegetation, most streptomycetes produce spores, and are noted for their distinct "earthy" odor that results from production of a volatile metabolite, geosmin. Streptomycetes are characterised by a complex secondary metabolism. They produce over two-thirds of the clinically useful antibiotics of natural origin (e.g., neomycin, streptomycin, cypemycin, grisemycin, bottromycins and chloramphenicol). The antibiotic streptomycin takes its name directly from ''Streptomyces''. Streptomycetes are infrequent pathogens, though infections in humans, such as mycetoma, can be caused by '' S. somaliensis'' and '' S. sudanensis'', and in plants can be caused by '' S. cavi ...

Leinamycin
Leinamycin is an 18-membered macrolactam produced by several species of ''Streptomyces atroolivaceus''. This macrolactam has also been shown to exhibit antitumor properties as well as antimicrobial properties against gram-positive and gram-negative bacteria. The presence of a spiro-fused 1,3-dioxo-1,2- dithiolane moiety was a unique structural property at the time of this compound's discovery and it plays an important role in leinamycin's antitumor and antibacterial properties due to its ability to inhibit DNA synthesis. Biosynthesis The seminal proposal for the biosynthesis Biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. In biosynthesis, simple compounds are modified, converted into other compounds, or joined to form macromolecules. ... of leinamycin was published in ''Chemistry & Biochemistry'' in 2004. This biosynthesis consists of a discrete and modular NRPS, AT-less PKSs, and PKS modu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mithramycin
Plicamycin (INN, also known as mithramycin; trade name Mithracin) is an antineoplastic antibiotic produced by ''Streptomyces plicatus''. It is an RNA synthesis inhibitor. The manufacturer discontinued production in 2000. Several different structures are currently reported in different places all with the same chromomycin core, but with different stereochemistry in the glycoside chain, a 1999 study has re-investigated the compound and proposed a revised structure. Uses Plicamycin has been used in the treatment of testicular cancer, Paget's disease of bone, and, rarely, the management of hypercalcemia. Plicamycin has been tested in chronic myeloid leukemia. Plicamycin is currently used in multiple areas of research, including cancer cell apoptosis and as a metastasis inhibitor. One elucidated pathway shows it interacts by cross-binding chromatin GC-rich promoter motifs, thereby inhibiting gene transcription.
