Comment typeDescription
CofactorName=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250}; Note=Binds 3 Mg(2+) ions per subunit. {ECO:0000250};
FunctionHeterodimeric geranyl(geranyl)-diphosphate (GPP) synthase small subunit. The small subunit alone is inactive in vitro while the large subunit GGPPS1 catalyzes mainly the production of geranygeranyl-diphosphate in vitro. Upon association of the two subunits, the product profile changes and the production of gerany-diphosphate is strongly increased. {ECO:0000269|PubMed:19482937}.
SimilarityBelongs to the FPP/GGPP synthase family. {ECO:0000305}.
Subcellular LocationPlastid, chloroplast {ECO:0000305}.
SubunitPart of a heterodimeric geranyl(geranyl)diphosphate synthase. Interacts with GGPPS1 or GGPPS2, but not with GGPPS9. {ECO:0000269|PubMed:19482937}.
Tissue SpecificityExpressed ubiquitously. {ECO:0000269|PubMed:10759500}.
