Protein

Geranylgeranyl pyrophosphate synthase

Gene

BTS1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the trans-addition of the 3 molecules of IPP onto DMAPP to form geranylgeranyl pyrophosphate. Required for the membrane attachment of YPT1 and SEC4. May be involved in vesicle trafficking and protein sorting.2 Publications

Miscellaneous

Present with 2840 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

Dimethylallyl diphosphate + isopentenyl diphosphate = diphosphate + geranyl diphosphate.
Geranyl diphosphate + isopentenyl diphosphate = diphosphate + (2E,6E)-farnesyl diphosphate.
(2E,6E)-farnesyl diphosphate + isopentenyl diphosphate = diphosphate + geranylgeranyl diphosphate.

Cofactori

Mg2+1 PublicationNote: Binds 3 Mg2+ ions per subunit.1 Publication

Kineticsi

  1. KM=3.2 µM for farnesyl diphosphate
  2. KM=0.8 µM for isopentenyl diphosphate

    Pathwayi: farnesyl diphosphate biosynthesis

    This protein is involved in step 1 of the subpathway that synthesizes farnesyl diphosphate from geranyl diphosphate and isopentenyl diphosphate.
    Proteins known to be involved in this subpathway in this organism are:
    1. Geranylgeranyl pyrophosphate synthase (BTS1), Farnesyl pyrophosphate synthase (ERG20)
    This subpathway is part of the pathway farnesyl diphosphate biosynthesis, which is itself part of Isoprenoid biosynthesis.
