Comment typeDescription
Alternative ProductsEvent=Alternative initiation; Named isoforms=2; Name=Mitochondrial; Synonyms=FPS1L; IsoId=Q09152-1; Sequence=Displayed; Name=Cytoplasmic; Synonyms=FPS1S; IsoId=Q09152-2; Sequence=VSP_018808;
Catalytic ActivityDimethylallyl diphosphate + isopentenyl diphosphate = diphosphate + geranyl diphosphate.
Catalytic ActivityGeranyl diphosphate + isopentenyl diphosphate = diphosphate + (2E,6E)-farnesyl diphosphate.
CofactorName=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250}; Note=Binds 3 Mg(2+) ions per subunit. {ECO:0000250};
FunctionCatalyzes the sequential condensation of isopentenyl pyrophosphate with the allylic pyrophosphates, dimethylallyl pyrophosphate, and then with the resultant geranylpyrophosphate to the ultimate product farnesyl pyrophosphate.
PathwayIsoprenoid biosynthesis; farnesyl diphosphate biosynthesis; farnesyl diphosphate from geranyl diphosphate and isopentenyl diphosphate: step 1/1.
PathwayIsoprenoid biosynthesis; geranyl diphosphate biosynthesis; geranyl diphosphate from dimethylallyl diphosphate and isopentenyl diphosphate: step 1/1.
SimilarityBelongs to the FPP/GGPP synthase family. {ECO:0000305}.
Subcellular LocationMitochondrion. Cytoplasm.
Tissue SpecificityThe FPS1L mRNA accumulates preferentially in inflorescences, whereas the FPS1S mRNA is predominantly expressed in roots and inflorescences.
