Extracellular siderophores of rapidly growing Aspergillus nidulans and Penicillium chrysogenum. 1982

G Charlang, and R M Horowitz, and P H Lowy, and B Ng, and S M Poling, and N H Horowitz

The highly active extracellular siderophores previously detected in young cultures of Aspergillus nidulans and Penicillium chrysogenum have been identified as the cyclic ester fusigen (fusarinine C), and its open-chain form, fusigen B (fusarinine B).

UI MeSH Term Description Entries
D007476 Ionophores Chemical agents that increase the permeability of biological or artificial lipid membranes to specific ions. Most ionophores are relatively small organic molecules that act as mobile carriers within membranes or coalesce to form ion permeable channels across membranes. Many are antibiotics, and many act as uncoupling agents by short-circuiting the proton gradient across mitochondrial membranes. Ionophore
D007501 Iron A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN. Iron-56,Iron 56
D007502 Iron Chelating Agents Organic chemicals that form two or more coordination links with an iron ion. Once coordination has occurred, the complex formed is called a chelate. The iron-binding porphyrin group of hemoglobin is an example of a metal chelate found in biological systems. Iron Chelates,Agents, Iron Chelating,Chelates, Iron,Chelating Agents, Iron
D010407 Penicillium A mitosporic Trichocomaceae fungal genus that develops fruiting organs resembling a broom. When identified, teleomorphs include EUPENICILLIUM and TALAROMYCES. Several species (but especially PENICILLIUM CHRYSOGENUM) are sources of the antibiotic penicillin. Penicilliums
D010408 Penicillium chrysogenum A mitosporic fungal species used in the production of penicillin. Penicillium chrysogeum,Penicillium notatum
D002621 Chemistry A basic science concerned with the composition, structure, and properties of matter; and the reactions that occur between substances and the associated energy exchange.
D005290 Ferric Compounds Inorganic or organic compounds containing trivalent iron. Compounds, Ferric
D006877 Hydroxamic Acids A class of weak acids with the general formula R-CONHOH. Hydroxamic Acid,Acid, Hydroxamic,Acids, Hydroxamic
D001233 Aspergillus nidulans A species of imperfect fungi from which the antibiotic nidulin is obtained. Its teleomorph is Emericella nidulans. Aspergillus nidulellus,Emericella nidulans
D017262 Siderophores Low-molecular-weight compounds produced by microorganisms that aid in the transport and sequestration of ferric iron. (The Encyclopedia of Molecular Biology, 1994) Siderophore,Siderochromes
