Catalysis of the reaction: 2 geranylgeranyl diphosphate = diphosphate + prephytoene diphosphate. Catalysis of the reaction: geranyl diphosphate + isopentenyl diphosphate = diphosphate + trans,trans-farnesyl diphosphate. Catalysis of the transfer of an alkyl or aryl (but not methyl) group from one compound (donor) to another (acceptor). Catalysis of the transfer of a geranylgeranyl group from geranylgeranyl diphosphate to (S)-3-O-geranylgeranylglyceryl phosphate to form (S)-2,3-di-O-geranylgeranylglyceryl phosphate. Catalysis of the transfer of a prenyl group from one compound (donor) to another (acceptor).
