Reconstruction of meroterpenoid quinone biosynthesis in B. braunii Showa. 47, phytyl diphosphate; 48, chlorophyll a (R=CH3) and b (R=CH2O); 49, α-tocopherol (vitamin E); 50, phylloquinone (vitamin K1); 51, plastoquinone-9; 52, ubiquinone (Coenzyme Q); 53, menaquinone (vitamin K2). ChlP, geranylgeranyl reductase; ChlG, chlorophyll synthase; HPT, homogentisate phytyltransferase; VTE1, tocopherol cyclase; GTMT, tocopherol methyltransferase; MenA, dihydroxynaphthoate octaprenyltransferase; UbiE, phylloquinone / menaquinone methyltransferase; HST, homogentisate solanesyltransferase; VTE3, methylsolanyl-benzoquinone methyltransferase (not found); Coq2, 4-hydroxybenzoate hexaprenyltransferase; Coq3, hexaprenyldihydroxybenzoate methyltransferase (two methylation reactions); Coq6, ubiquinone biosynthesis monoonxygenase; Coq5, ubiquinone biosynthesis methyltransferase; Coq7, ubiquinone biosynthesis monooxygenase. Terpenoid side chains are highlighted in gray.
