Glossary: | lycopaoctaene = 15,15′-dihydrophytoene = (6E,10E,14E,18E,22E,26E)-2,6,10,14,19,23,27,31-octamethyldotriaconta-2,6,10,14,18,22,26,30-octaene | ||||

Systematic name: | geranylgeranyl-diphosphate:geranylgeranyl diphosphate geranylgeranyltransferase | ||||
Comments: | The enzyme, characterized from the green microalga Botryococcus braunii race L, in involved in biosynthesis of (14E,18E)-lycopadiene. In vitro, the enzyme can accept (2E,6E)-farnesyl diphosphate and phytyl diphosphate as substrates, and is also able to catalyse the condensation of two different substrate molecules, forming chimeric products. However, the use of these alternative substrates is not significant in vivo. | ||||
