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

ppaARegulatory protein, PpaA; IMG reference gene:2512955290. (264 aa)    
Predicted Functional Partners:
ppsR
Transcriptional regulator, PpsR; IMG reference gene:2512955289; PFAM: Bacterial regulatory protein, Fis family; TIGRFAM: transcriptional regulator PpsR.
 
  
 0.981
bchF
IMG reference gene:2512955291; PFAM: 2-vinyl bacteriochlorophyllide hydratase (BCHF); TIGRFAM: 2-vinyl bacteriochlorophyllide hydratase.
 
  
 0.954
pufA
LHI alpha, Light-harvesting B875 protein; Antenna complexes are light-harvesting systems, which transfer the excitation energy to the reaction centers.
  
  
 0.925
bchC
Chlorophyll synthesis pathway, bchC; This protein catalyzes the penultimate step in bacteriochlorophyll a biosynthesis.
 
  
 0.914
crtE
Farnesyl-diphosphate synthase; 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.
  
  
 0.914
crtA
Spheroidene monooxygenase; IMG reference gene:2512955279.
  
  
 0.898
bchN
Ferredoxin protochlorophyllide reductase subunit N; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The NB-protein (BchN-BchB) is the catalytic component of the complex.
 
    0.882
pufB
LHI beta, Light-harvesting B875 subunit; Antenna complexes are light-harvesting systems, which transfer the excitation energy to the reaction centers.
  
   
 0.882
acsF
Mg-protoporphyrin IX monomethyl ester (oxidative) cyclase; Catalyzes the formation of the isocyclic ring in chlorophyll biosynthesis. Mediates the cyclase reaction, which results in the formation of divinylprotochlorophyllide (Pchlide) characteristic of all chlorophylls from magnesium-protoporphyrin IX 13-monomethyl ester (MgPMME); Belongs to the AcsF family.
 
  
 0.881
crtD
Methoxyneurosporene dehydrogenase; Catalyzes the introduction of C-3,4 double bonds into 1- hydroxyneurosporene (1-HO-Neu) to yield demethylspheroidene (DMS). It prefer the acyclic carotenoids such as 1-hydroxylycopene, and 1- hydroxy-gamma-carotene, whereas 1-hydroxy-3,4-didehydrolycopene and 1,1-dihydroxylycopene are much less effective.
