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

fdxHHeterocyst ferredoxin; Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. Donates electrons to the nitrogenase. (99 aa)    
Predicted Functional Partners:
hoxF
Hydrogenase subunit; ORF_ID:alr0752; hoxF gene product.
  
 
 0.953
nifU
Nitrogen fixation protein; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.
 
 0.949
hesB
HesB protein; May be required for efficient nitrogen fixation.
  
 
 0.880
hesA
HesA protein; May be required for efficient nitrogen fixation.
     
 0.825
alr2679
Polyketide synthase; ORF_ID:alr2679.
   
 
 0.806
alr2680
Polyketide synthase; ORF_ID:alr2680.
   
 
 0.801
all1649
ORF_ID:all1649; similar to polyketide synthase.
   
 
 0.777
all2635
Polyketide synthase type I; ORF_ID:all2635.
   
 
 0.777
psaF
Photosystem I subunit III precursor; Probably participates in efficiency of electron transfer from plastocyanin to P700 (or cytochrome c553 in algae and cyanobacteria). This plastocyanin-docking protein contributes to the specific association of plastocyanin to PSI; Belongs to the PsaF family.
  
 
 0.769
psaD
Photosystem I reaction center subunit II; PsaD can form complexes with ferredoxin and ferredoxin- oxidoreductase in photosystem I (PS I) reaction center.
