Mutational biosynthesis by idiotrophs of Micromonospora purpurea. II. Conversion of non-amino containing cyclitols to aminoglycoside antibiotics. 1977

S J Daum, and D Rosi, and W A Goss

A mutant of Micromonospora purpurea, which produces the gentamicin complex only when 2-deoxystreptamine is added to the fermentation medium, produces a new antibiotic complex, 2-hydroxygentamicin, when streptamine or 2,4,6/3,5-pentahydroxycyclohexanone is added to the fermentation medium. This mutant also produces the gentamicin complex when 2,4/3,5-tetrahydroxycyclohexanone is added to the fermentation medium. The C1 and C2 components of 2-hydroxygentamicin have broad spectrum in vitro antibacterial activity similar to the gentamicin C1 and C2 components, but with greater activity against some gentamicin-resistant strains.

UI	MeSH Term	Description	Entries
D008847	Micromonospora	A genus of gram-positive bacteria that forms a branched mycelium. It commonly occurs as a saprophytic form in soil and aquatic environments.	Micromonospora echinospora
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
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.
D005839	Gentamicins	A complex of closely related aminoglycosides obtained from MICROMONOSPORA purpurea and related species. They are broad-spectrum antibiotics, but may cause ear and kidney damage. They act to inhibit PROTEIN BIOSYNTHESIS.	Gentamicin Sulfate (USP),Gentamycin,G-Myticin,Garamycin,Gentacycol,Gentamicin,Gentamicin Sulfate,Gentamycins,Gentavet,Genticin,G Myticin,GMyticin,Sulfate, Gentamicin
D001419	Bacteria	One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.	Eubacteria
D055598	Chemical Phenomena	The composition, structure, conformation, and properties of atoms and molecules, and their reaction and interaction processes.
