RESUMO

Complementation of defined actinorhodin beta-ketoacyl synthase (KS) mutants by various other KS genes suggested that the ORF1-encoded KS may be relatively generalized in function, whereas the ORF2-encoded KS component may provide specificity in polyketide chain construction. Evidence for differential temporal-spatial expression of the actinorhodin and spore pigment KSs in Streptomyces coelicolor was obtained.
