STRINGSTRING
psaJ protein (Nostoc sp. PCC7120) - STRING interaction network
"psaJ" - Photosystem I reaction center subunit IX in Nostoc sp. PCC7120
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

psaJPhotosystem I reaction center subunit IX; May help in the organization of the PsaE and PsaF subunits (49 aa)    
Predicted Functional Partners:
psaF
Photosystem I reaction center subunit III; 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 (164 aa)
 
 
  0.999
psaA
Photosystem I P700 chlorophyll a apoprotein A1; 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 (752 aa)

psaB1
Photosystem I P700 chlorophyll a apoprotein A2 1; 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 (By similarity) (741 aa)
       
  0.996
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/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 accept [...] (81 aa)
       
  0.996
psaD
Photosystem I reaction center subunit II; PsaD can form complexes with ferredoxin and ferredoxin- oxidoreductase in photosystem I (PS I) reaction center (139 aa)
       
  0.995
all0107
annotation not available (172 aa)
     
  0.916
ycf4
Photosystem I assembly protein Ycf4; Seems to be required for the assembly of the photosystem I complex (198 aa)
   
   
  0.912
psaK1
annotation not available (86 aa)
       
  0.899
ycf3
Photosystem I assembly protein Ycf3; Essential for the assembly of the photosystem I (PSI) complex. May act as a chaperone-like factor to guide the assembly of the PSI subunits (173 aa)
           
  0.838
psaE
Photosystem I reaction center subunit IV; Stabilizes the interaction between PsaC and the PSI core, assists the docking of the ferredoxin to PSI and interacts with ferredoxin-NADP oxidoreductase (70 aa)
