Incorporation of sarcosine into the actinomycins synthesized by Streptomyces antibioticus.

Sarcosine is an amino acid apparently not widely distributed in Nature. As a free amino acid, sarcosine has been demonstrated in the radial caeca of the starfish Astropecten aurantiacus (Kossel & Edlbacher, 1915), in the muscles of Elasmobranchii (Tarr, 1958) and in the reindeer moss, Cladonia itlvatica (Linko, Alfthan, Miettinen & Virtanen, 1953). Sarcosine has been found bound in peptides in ...

Biosynthesis of the actinomycin chromophore: incorporation of 3-hydroxy-4-methylanthranilic acid into actinomycins by Streptomyces antibioticus.

Actinomycin synthesis by washed mycelia of Streptomyces antibioticus has been conducted in the presence of 3-hydroxy-4-methylanthranilate-(carboxyl-(14)C). Incorporation of this compound into actinomycins has been observed, which constitutes further evidence that 3-hydroxy-4-methylanthranilate is an intermediate in actinomycin biosynthesis. The position of the incorporated label has been determ...

Origin of the sarcosine molecules of actinomycins.

1. Streptomyces V-187 produces on minimal medium a mixture composed mainly of actinomycin C(1) (actinomycin D) and actinomycin A(1) (actinomycin I). If sarcosine is added to the medium, the micro-organism produces, in addition to actinomycins C(1) and A(1), actinomycin F(8) (actinomycin II) and actinomycin F(9) (actinomycin (III), characterized by the substitution by sarcosine of one or both th...

Ribonucleic acid synthesis in Streptomyces antibioticus: stable ribonucleic acid species synthesized by young and old cells.

In studies of RNA synthesis by intact cells and cell-free extracts of Streptomyces antibioticus, it has been found that 48 hr cells (producing actinomycin) and cell-free extracts are less efficient than 12 hr cells (not producing actinomycin) and extracts in the synthesis of RNA. Analysis of the products of "in viva" and "in vitro" RNA synthesis by sucrose gradient cent trifugation reveals that...

The possible involvement of a plasmid(s) in actinomycin synthesis by Streptomyces parvulus and Streptomyces antibioticus.

The treatment of Streptomyces parvulus and Streptomyces antibioticus with acriflavine or novobiocin resulted in the loss of ability to produce actinomycin. The concomitant loss of ability to form aerial mycelium and the incidence of auxotrophic progeny (S. parvulus) were both low relative to the loss of the antibiotic-producing property. Protoplast fusion induced by polyethylene glycol 4000, us...
