STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

pysPhytoene synthase; Involved in the biosynthesis of carotenoids. Catalyzes the condensation of two molecules of geranylgeranyl diphosphate (GGPP) to give prephytoene diphosphate (PPPP) and the subsequent rearrangement of the cyclopropylcarbinyl intermediate to yield 15-cis-phytoene. (337 aa)    
Predicted Functional Partners:
pds
Phytoene desaturase; This enzyme converts phytoene into zeta-carotene via the intermediary of phytofluene by the symmetrical introduction of two double bonds at the C-11 and C-11' positions of phytoene.
  
 0.999
crtE
Geranylgeranyl pyrophosphate synthase; ORF_ID:slr0739; Belongs to the FPP/GGPP synthase family.
  
 0.998
crtQ
Zeta-carotene desaturase precursor; Catalyzes the conversion of zeta-carotene to lycopene via the intermediary of neurosporene. It carries out two consecutive desaturations (introduction of double bonds) at positions C-7 and C-7' (By similarity).
   
 0.992
crtO
B-carotene ketolase; ORF_ID:slr0088.
  
 0.991
bhy
B-carotene hydroxylase; ORF_ID:sll1468.
  
  
 0.983
sll1091
43 kD bacteriochlorophyll synthase subunit; Catalyzes the stepwise hydrogenation of geranylgeraniol to phytol during chlorophyll A (ChlA) biosynthesis.
 
 
 0.918
crtX
Zeaxanthin glucosyl transferase; ORF_ID:slr1125.
     
 0.913
sll0033
ORF_ID:sll0033; unknown protein.
  
 0.905
sds
Solanesyl diphosphate synthase; Possible role in synthesis of the nonaprenyl side chain of plastoquinone or in synthesis of other prenyl chains such as undekaprenyl pyrophosphate; Belongs to the FPP/GGPP synthase family.
  
 0.898
slr1293
ORF_ID:slr1293; unknown protein.
 
  
 0.870
