La ausencia de pSCL4 en la cepa S. The microarrays used contained genes for secondary metabolites biosynthesis, nitrogen and carbon utilization, arginine biosynthesis and all those genes known previously to the S. Estudios iniciales indicaban que la cepa Streptomyces sp. Possible cross-regulation of two unrelated secondary metabolite pathways. The CA gene cluster of S.

Streptomyces – buleria

Cross-regulation among disparate antibiotic biosynthetic pathways of Streptomyces coelicolor. B Naringenin production at 84 h of cultures by S.

The linkage of the ncs and ncyP genes may be relevant for efficient formation of naringenin see Discussion. The ccaR gene of S.

Indian J Pediatr ; Therefore, the concomitant lower copy number of the three plasmids, pSCL1, pSCL2 and pSCL4, suggest that a different gene controlling the copy number of all the plasmids different from parA-parB appears to be spontaneously altered in S.


Int J Radiat Biol. Construction of the complemented strains. In the clavulanic acid cluster, CcaR binds sequences upstream of ceaS2, which encodes the first enzyme of the CA pathway, and of claR, for the Lys-type regulator controlling late steps in CA biosynthesis Santamarta et al.
