Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the condensation of farnesyl diphosphate (FPP) and isopentenyl diphosphate (IPP) to yield geranylgeranyl diphosphate (GGPP) needed for biosynthesis of carotenoids and diterpenes.By similarity

Catalytic activityi

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

Cofactori

Mg2+By similarityNote: Binds 3 Mg2+ ions per subunit.By similarity

Pathwayi: geranylgeranyl diphosphate biosynthesis

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

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
