Remarks "This type III PKS containing cluster is involved in the formation of red-brown pigment/melanin, and equivalent clusters have been studied in other organisms, e.g. PMID 10476972; 11723138; 15659395; 15701630; 16291687. The PKS product THN (1,3,6,8-tetrahydroxynaphthalene) of these clusters are variously oxidized/dimerized/polymerized by the action of additional enzymes in the cluster including a cytochrome P450 monooxygenase (RppB) and a monooxygenase of the cupin domain superfamily. The products of these clusters have been shown to provide resistance to UV radiation. Flaviolin rhamnoside is believed to be a shunt metabolite, or by-product, in which flaviolin is serendipitously used as an aglycone substrate by some unidentified glycosyl transferase."
