"crtB" - Phytoene synthase in Synechocystis sp. PCC6803
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

crtBPhytoene 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 all-trans phytoene (309 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 (472 aa)
 
  0.999
crtE
Geranylgeranyl pyrophosphate synthase (302 aa)
   
  0.997
crtQ
Zeta-carotene desaturase; 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) (489 aa)
 
  0.995
crtO
B-carotene ketolase (542 aa)
 
 
  0.993
sll0033
Hypothetical protein (501 aa)
 
  0.982
preA
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 (323 aa)
   
  0.978
slr1293
Hypothetical protein (507 aa)
 
 
  0.972
crtX
Zeaxanthin glucosyl transferase (419 aa)
         
  0.962
sll0254
Hypothetical protein (650 aa)
   
 
  0.933
chlP
Geranylgeranyl reductase; Catalyzes the stepwise hydrogenation of geranylgeraniol to phytol during chlorophyll A (ChlA) biosynthesis (407 aa)
