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

Functioni

Bifunctional enzyme that catalyzes the reactions from geranylgeranyl diphosphate to phytoene (phytoene synthase) and lycopene to beta-carotene via the intermediate gamma-carotene (lycopene cyclase).By similarity

Catalytic activityi

Carotenoid psi-end group = carotenoid beta-end group.
2 geranylgeranyl diphosphate = 15-cis-phytoene + 2 diphosphate.

Pathwayi: beta-carotene biosynthesis

This protein is involved in the pathway beta-carotene biosynthesis, which is part of Carotenoid biosynthesis.
View all proteins of this organism that are known to be involved in the pathway beta-carotene biosynthesis and in Carotenoid biosynthesis.

Pathwayi: phytoene biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes all-trans-phytoene from geranylgeranyl diphosphate.
Proteins known to be involved in this subpathway in this organism are:
  1. Bifunctional lycopene cyclase/phytoene synthase (sr13176)
This subpathway is part of the pathway phytoene biosynthesis, which is itself part of Carotenoid 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.
