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

ABB57008.1ferredoxin-NADP oxidoreductase. (403 aa)    
Predicted Functional Partners:
petF
Ferredoxin (2Fe-2S); Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions.
  
 
 
 0.935
narB
Assimilatory nitrate reductase (ferredoxin) precursor; Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants, fungi and bacteria; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
 
      0.899
petJ
Cytochrome C6 soluble cytochrome f; Functions as an electron carrier between membrane-bound cytochrome b6-f and photosystem I in oxygenic photosynthesis.
  
   
 0.736
petJ-2
Cytochrome c553; Functions as an electron carrier between membrane-bound cytochrome b6-f and photosystem I in oxygenic photosynthesis.
      
 0.701
ABB58572.1
Putative cytochrome C6-2.
  
   
 0.666
psaL
Hypothetical protein.
  
  
 0.660
ABB57032.1
Photosystem I reaction center subunit II.
  
  
 0.632
psaC
Photosystem I iron-sulfurcenter; Apoprotein for the two 4Fe-4S centers FA and FB of photosystem I (PSI); essential for photochemical activity. FB is the terminal electron acceptor of PSI, donating electrons to ferredoxin. The C-terminus interacts with PsaA/B/D and helps assemble the protein into the PSI complex. Required for binding of PsaD and PsaE to PSI. PSI is a plastocyanin/cytochrome c6-ferredoxin oxidoreductase, converting photonic excitation into a charge separation, which transfers an electron from the donor P700 chlorophyll pair to the spectroscopically characterized acceptor [...]

cp12
Conserved hypothetical protein.
  
   
 0.605
