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

petF1TIGRFAM: ferredoxin [2Fe-2S]; PFAM: ferredoxin; KEGG: cyb:CYB_1598 ferredoxin, 2Fe-2S. (99 aa)    
Predicted Functional Partners:
ACK64204.1
PFAM: Respiratory-chain NADH dehydrogenase domain 51 kDa subunit; KEGG: syp:SYNPCC7002_A0196 hydrogenase large diaphorase subunit F.
  
 
 0.923
ACK64476.1
PFAM: photosystem I protein PsaD; KEGG: syn:slr0737 photosystem I reaction center subunit II.
  
 
 
 0.895
psaE
Photosystem I reaction centre subunit IV/PsaE; Stabilizes the interaction between PsaC and the PSI core, assists the docking of the ferredoxin to PSI and interacts with ferredoxin-NADP oxidoreductase; Belongs to the PsaE family.
  
 
 
 0.894
psaA
Photosystem I core protein PsaA; PsaA and PsaB bind P700, the primary electron donor of photosystem I (PSI), as well as the electron acceptors A0, A1 and FX. 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 acceptors A0, A1, FX, FA and FB in turn. Oxidized P700 is reduced on the lumenal side of the thylakoid membrane by plastocyanin or cytochrome c6.

ACK65073.1
PFAM: ferredoxin thioredoxin reductase alpha chain; KEGG: mar:MAE_01240 ferredoxin-thioredoxin reductase variable subunit.
    
   0.844
ACK65577.1
Ferredoxin thioredoxin reductase beta chain; Catalytic subunit of the ferredoxin-thioredoxin reductase (FTR), which catalyzes the two-electron reduction of thioredoxins by the electrons provided by reduced ferredoxin.
   
   0.842
psaC
Photosystem I iron-sulfur protein PsaC; 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 a [...]

ACK67370.1
PFAM: photosystem I reaction center protein PsaF subunit III; KEGG: syn:sll0819 photosystem I reaction center subunit III precursor (PSI-F).
  
 
 0.828
ACK66551.1
PFAM: oxidoreductase FAD/NAD(P)-binding domain protein; CpcD phycobilisome linker domain protein; KEGG: mar:MAE_12570 ferredoxin-NADP oxidoreductase.
  
 
 
 0.811
psaB
Photosystem I core protein PsaB; PsaA and PsaB bind P700, the primary electron donor of photosystem I (PSI), as well as the electron acceptors A0, A1 and FX. 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 acceptors A0, A1, FX, FA and FB in turn. Oxidized P700 is reduced on the lumenal side of the thylakoid membrane by plastocyanin or cytochrome c6; Belongs to the PsaA/PsaB family.
