Isolation of mutants blocked in calicheamicin biosynthesis.

Blocked mutants of Micromonospora echinospora defective in the production of the potent antitumor agent calicheamicin are described. Analysis of intermediates produced by blocked mutants indicates a branched biosynthetic pathway. Mutants that produced some, but not all, calicheamicin forms are also described.

Aromatic biosynthesis. IV. Preferential conversion, in incompletely blocked mutants, of a common precursor of several metabolites.

Mutants of Escherichia coli have been isolated with blocks in a variety of reactions in aromatic biosynthesis. In addition to strains with single requirements for tyrosine, phenylalanine, tryptophan, and p-aminobenzoic acid, respectively, strains have been obtained with requirements for the first two, the first three, and all four of these compounds (Davis, 1950a). Moreover, most of the mutants...

Biosynthesis of the antibiotic actinorhodin. Analysis of blocked mutants of Streptomyces coelicolor.

From two types of class V act mutants of Streptomyces coelicolor two monomeric precursors of actinorhodin have been isolated and their structures determined. One is the known antibiotic kalafungin and the other a new compound. Their relationship to actinorhodin biosynthesis is discussed.

Biosynthesis of hibarimicins. II. Elucidation of biosynthetic pathway by cosynthesis using blocked mutants.

The biosynthetic pathway of hibarimicin (HBM) was proposed on the basis of the experimental results obtained by using blocked mutants of Microbispora rosea subsp. hibaria TP-A0121, the HBM producer. In its biosynthesis, the oxidative coupling of the aromatic undecaketide unit generates a symmetrical aglycon HMP-Y1 (hibarimicin-mutant product Y1), which is oxidatively modified to hibarimicinone,...

Biosynthesis of astromicin and related antibiotics. II. Biosynthetic studies with blocked mutants of Micromonospora olivasterospora.

An inosamine-idiotrophic mutant, KY11559, which produced no astromicin unless scyllo-inosamine was added to the fermentation medium, was isolated from Micromonospora olivasterospora. Biotransformation studies were performed with resting cells of this mutant and compounds assumed to be precursors of 1,4-diaminocyclitol (fortamine). Scyllo-inosose, scyllo-inosamine and FU-10 were converted to ast...
