Distamycin A and netropsin are basic oligopeptide antibiotics. Though the chemical structure of both antibiotics is very similar, the action on grampositive and gramnegative bacteria is quite different. Distamycin A acts only on grampositive bacteria

The activities of some NADP-specific enzymes and of corresponding metabolic pathways were studied in mycelium extracts of Streptomyces hygroscopicus JA 6599 strains producing different yields of the macrolide antibiotic A 6599. Isocitrate dehydrogena

The possible role of some metabolic systems producing acetyl-CoA, malonyl-CoA, and methylmalonyl-CoA as initial precursors in the biosynthesis of the macrolide antibiotic A 6599 by Streptomyces hygroscopicus JA 6599 was studied. The activities of pyr

The biosynthesis of nourseothricin, a streptothricin type antibiotic, is strongly stimulated by o-aminobenzoic acid in cultures of S. noursei JA 3890 b. o-Aminobenzoic acid (OAB) was shown to interfere with the amino acid metabolism and to influence

The polyene macrolide antibiotics are active against yeast, fungi, and other eukaryotic cells, but are with a few exceptions inactive against bacteria. The resistance of bacteria against these compounds is usually explained by the absence of sterols

o-Aminobenzoic acid (OABA) known by its stimulatory effect on streptothricin biosynthesis by Streptomyces noursei JA 3890b was found to suppress specifically the formation of cytochrome a-type terminal oxidase while the levels of the b- and c-type cy

The effect of streptothricin F on macromolecular syntheses in intact cells and cell-free protein synthesis of E. coli was studied. The results indicate that protein synthesis is the primary site of inhibition by streptothricin F in growing E. coli ce

Short-chain alcohols, benzyl alcohol and Tween 20 were found capable of switching over the metabolic flux in Streptomyces noursei JA 3890b from the preference of oxidative deamination of alanine towards the reinforced acquisition of NH4+. These chang
