General annotation (Comments)

Function	Catalyzes the sequential condensation of isopentenyl pyrophosphate with the allylic pyrophosphates, dimethylallyl pyrophosphate, and then with the resultant geranylpyrophosphate to the ultimate product farnesyl pyrophosphate.
Catalytic activity	Dimethylallyl diphosphate + isopentenyl diphosphate = diphosphate + geranyl diphosphate. Geranyl diphosphate + isopentenyl diphosphate = diphosphate + trans,trans-farnesyl diphosphate.
Pathway	Isoprenoid biosynthesis; farnesyl-PP biosynthesis; farnesyl-PP from geranyl-PP and isopentenyl-PP: step 1/1. Isoprenoid biosynthesis; geranyl-PP biosynthesis; geranyl-PP from dimethylallyl-PP and isopentenyl-PP: step 1/1.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the FPP/GGPP synthetase family.
