Abstract: Actinomycetes, Vol. 5, Part 1, 14-22, 1993 Purine metabolites as interspecific stimulators of setomimycin formation by Streptomyces aurantiacus U. GRAFE, W. IHN and I. ERITT Code Number: AC94004 File Sizes: Text: 24K Graphics: Line Drawings (Gif) - 203K Photo (Jpg) - 39K / Halftone 29K ABSTRACT. The formation of a yellow pigment (setomimycin) is strongly stimulated in surface cultures of S. aurantiacus JA 4570/5 by cell-free culture broth of Streptomyces griseus and some other streptomyces strains. Reduced nicotinamide-adenine-dinucleotide (NADH) was identified as one of the inducing principles from S.griseus JA 8407/299, but other purines, such as NAD(P)(H), adenosine and guanosine phosphates, and pyridoxal 5'-phosphate as well, displayed the same effect. The results suggest that actinomycetes secrete purines into the medium and that these nucleotides and cofactors could regulate secondary metabolite formation. Copyright 1994 C. E. T. A.
