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

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 phytoene (By similarity). Belongs to the phytoene/squalene synthase family. (339 aa)    
Predicted Functional Partners:
crtI
Phytoene dehydrogenase; Converts phytoene into all-trans-neurosporene as the major product, via the intermediary of phytofluene and zeta-carotene, by the introduction of three double bonds. Both intermediates, phytofluene and zeta-carotene, can be used as substrates and converted to neurosporene. 1,2-epoxy phytoene is also a suitable substrate whereas the C30 diapophytoene is not; Belongs to the carotenoid/retinoid oxidoreductase family.
 
 0.999
crtE
Farnesyltranstransferase; Catalyzes the condensation of farnesyl diphosphate (FPP) and isopentenyl diphosphate (IPP) to yield geranylgeranyl diphosphate (GGPP) needed for biosynthesis of carotenoids and diterpenes. Belongs to the FPP/GGPP synthase family.
 
 0.993
bchP
Geranylgeranyl reductase; Catalyzes the stepwise hydrogenation of geranylgeraniol to phytol during bacteriochlorophyll A (BchlA) biosynthesis.
 
 
 0.986
crtD
Methoxyneurosporene dehydrogenase; Catalyzes the introduction of C-3,4 double bonds into 1- hydroxyneurosporene (1-HO-Neu) to yield demethylspheroidene (DMS).
  
 0.986
crtC
Hydroxyneurosporene synthase; Involved in the biosynthesis of carotenoids spheroidene and spirilloxanthin. Catalyzes the hydration of neurosporene to the corresponding hydroxylated carotenoids 1-HO-neurosporene and that of lycopene to 1-HO-lycopene. It exhibits negligible activity in converting HO-neurosporene, HO-lycopene, or any other derivative such as spheroidene, 1-HO-3,4-didehydrolycopene.
 
  
 0.965
crtA
Spheroidene monooxygenase; Catalyzes the asymmetrical introduction of one keto group at the C-2 position of spheroidene and two keto groups at the C-2 and C-2' positions of spirilloxanthin.
 
  
 0.962
ispA
Geranyltranstransferase; Belongs to the FPP/GGPP synthase family.
  
 0.940
bchI
Magnesium chelatase ATPase subunit I; Involved in bacteriochlorophyll biosynthesis; introduces a magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX; Belongs to the Mg-chelatase subunits D/I family.
 
  
 0.932
bchD
Magnesium chelatase ATPase subunit D; Involved in bacteriochlorophyll biosynthesis; introduces a magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX; Belongs to the Mg-chelatase subunits D/I family.
 
  
 0.927
ispB
Octaprenyl-diphosphate synthase; Belongs to the FPP/GGPP synthase family.
  
 0.925
