Structural highlights
Function
RPPA_STRCO Involved in the biosynthesis of melanin but also various secondary metabolites containing a naphthoquinone ring. Catalyzes the iterative condensation of five CoA-linked malonyl units to form a pentaketide intermediate. THNS subsequently catalyzes the dual intramolecular Claisen and aldol condensations of this linear intermediate to produce the fused ring of 1,3,6,8-tetrahydroxynaphthalene (THN).[1] [2]
