CC   -!- FUNCTION: Involved in developmentally regulated synthesis of a compound
CC       biosynthetically related to polyketide antibiotics which is essential
CC       for spore color in Streptomyces coelicolor.
CC   -!- SIMILARITY: Belongs to the thiolase-like superfamily. Beta-ketoacyl-ACP
CC       synthases family. {ECO:0000305}.
