pubmed:abstractText |
The relA gene from Streptomyces antibioticus has been cloned and sequenced. The gene encodes a protein with an Mr of 93,653, which is 91% identical to the corresponding protein from Streptomyces coelicolor. Disruption of S. antibioticus relA produces a strain which grows significantly more slowly on actinomycin production medium than the wild type or a disruptant to which the intact relA gene was restored. Moreover, the disruptant was unable to accumulate ppGpp to the levels observed during the normal course of growth and actinomycin production in the wild type. The strain containing the disrupted relA gene did not produce actinomycin and contained significantly lower levels of the enzyme phenoxazinone synthase than the wild-type strain. Actinomycin synthetase I, a key enzyme in the actinomycin biosynthetic pathway, was undetectable in the relA disruptant. Growth of the disruptant on low-phosphate medium did not restore actinomycin production.
