ID 2.5.1.148 DE lycopaoctaene synthase. CA 2 (2E,6E,10E)-geranylgeranyl diphosphate + H(+) + NADPH = all-trans- CA lycopaoctaene + 2 diphosphate + NADP(+). CC -!- The enzyme, characterized from the green microalga Botryococcus CC braunii race L, in involved in biosynthesis of (14E,18E)-lycopadiene. CC -!- In vitro, the enzyme can accept (2E,6E)-farnesyl diphosphate and CC phytyl diphosphate as substrates, and is also able to catalyze the CC condensation of two different substrate molecules, forming chimeric CC products. CC -!- However, the use of these alternative substrates is not significant CC in vivo. DR A0A142ZC57, LOS_BOTBR ; //
