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

B4FAW3_MAIZE
Photosystem I reaction center subunit II-1 chloroplastic.
  
 
 0.999
psaC
Photosystem I iron-sulfur center; 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-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, [...]

A0A1D6HY75
Photosystem I reaction center subunit IV A.
  
 
 0.998
B6SRI3_MAIZE
Photosystem I reaction center subunit III.
  
 
 0.998
psaB
Photosystem I P700 chlorophyll a apoprotein A2; 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-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.

psaI
Photosystem I reaction center subunit VIII; May help in the organization of the PsaL subunit. Belongs to the PsaI family.
   
 
 0.996
psaJ
Photosystem I reaction center subunit IX; May help in the organization of the PsaE and PsaF subunits. Belongs to the PsaJ family.
   
 
 0.996
PSAH
Photosystem I reaction center subunit VI, chloroplastic; Possible role could be the docking of the LHC I antenna complex to the core complex; Belongs to the psaH family.
