Analysis of type II polyketide beta-ketoacyl synthase specificity in Streptomyces coelicolor A3(2) by trans complementation of actinorhodin synthase mutants

J Bacteriol. 1994 Mar;176(6):1801-4. doi: 10.1128/jb.176.6.1801-1804.1994.

Abstract

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.
