picture info	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 ...

picture info	Nosiheptide Nosiheptide is a thiopeptide antibiotic produced by the bacterium ''Streptomyces actuosus''. Chemical classification Nosiheptide is classified, along with several others, as an e series thiopeptide characterized by a nitrogen containing, 6-membered heterocycle in a 2,3,5,6 substituted fashion central to multiple azoles (or azolines) and dehydroamino acids along with a macrocyclic core. Nosiheptide is constructed solely of proteinogenic amino acids and has ribosomal origin, making it a member of the ribosomally synthesized and posttranslationally modified peptide family of natural products. Thiopeptides such as nosiheptide have potent activity against various bacterial pathogens, primarily gram positive, including methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, and vancomycin-resistant enterococci. Composition Nosiheptide consists of 5 thiazole rings, a central tetrasubstituted pyridine moiety, and a bicyclic macrocycle, which incl ...

picture info	Staurosporin Staurosporine (antibiotic AM-2282 or STS) is a natural product originally isolated in 1977 from the bacterium ''Streptomyces staurosporeus''. It was the first of over 50 alkaloids to be isolated with this type of bis-indole chemical structure. The chemical structure of staurosporine was elucidated by X-ray analysis of a single crystal and the absolute stereochemical configuration by the same method in 1994. Staurosporine was discovered to have biological activities ranging from anti-fungal to anti-hypertensive. The interest in these activities resulted in a large investigative effort in chemistry and biology and the discovery of the potential for anti-cancer treatment. Biological activities The main biological activity of staurosporine is the inhibition of protein kinases through the prevention of ATP binding to the kinase. This is achieved through the stronger affinity of staurosporine to the ATP-binding site on the kinase. Staurosporine is a prototypical ATP-competitive kinase ...
