Regulatory mechanisms controlling antibiotic production in Streptomyces clavuligerus.
Streptomyces clavuligerus produces a large array of natural compounds with antibiotic, antitumor, beta-lactamase inhibition or inmunomodulating activities. The production of cephamycin C, clavulanic acid and other compounds with a clavam structure has been studied for many years. A network of regulatory mechanisms is present in S. clavuligerus to control the formation of different compounds by pathway-specific regulators or pleiotropic regulators. The possible existence of a gamma-butyrolactone signaling system in this streptomycete is emerging. In addition, S. clavuligerus possesses a stringent control mechanism somehow different from those previously reported in other Streptomyces species.
