Actinorhodin is a benzoisochromanequinone dimer polyketide antibiotic produced by Streptomyces coelicolor. The gene cluster responsible for actinorhodin production contains the biosynthetic enzymes and genes responsible for export of the antibiotic. The antibiotic also has the effect of being a pH indicator due to its pH-dependent color change. It is a product of a Type II polyketide synthase biosynthetic pathway.
