geranylgeranyl diphosphate synthase activity [GO_0004311]

Catalysis of the reaction: (2E,6E)-farnesyl diphosphate + isopentenyl diphosphate = (2E,6E,10E)-geranylgeranyl diphosphate + diphosphate.

geranylgeranyl diphosphate synthase activity

ID: GO_0004311

Class

Catalysis of the reaction: (2E,6E)-farnesyl diphosphate + isopentenyl diphosphate = (2E,6E,10E)-geranylgeranyl diphosphate + diphosphate.

The catalyzed reaction forms (free) geranylgeranyl diphosphate. There is no relationship between this activity and protein farnesyltransferase activity, GO:0004660, where the catalyzed reaction transfers a farnesyl group from farnesyl diphosphate to a target protein.
