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

psbQPhotosystem II protein PsbQ. (150 aa)    
Predicted Functional Partners:
psbU
Photosystem II oxygen evolving complex protein PsbU; Stabilizes the structure of photosystem II oxygen-evolving complex (OEC), the ion environment of oxygen evolution and protects the OEC against heat-induced inactivation.
  
 
 
 0.948
psbB
Photosystem II chlorophyll-binding protein CP47; One of the components of the core complex of photosystem II (PSII). It binds chlorophyll and helps catalyze the primary light- induced photochemical processes of PSII. PSII is a light-driven water:plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation; Belongs to the PsbB/PsbC family. PsbB subfamily.
  
 
   0.943
psbO
Photosystem II manganese-stabilizing protein PsbO.
    
 
 0.936
psbV
Photosystem II cytochrome c-550 precursor PsbV; Low-potential cytochrome c that plays a role in the oxygen- evolving complex of photosystem II.
    
 
 0.933
psbT
Photosystem II protein PsbT; Seems to play a role in the dimerization of PSII. Belongs to the PsbT family.
  
 
   0.861
psbM
Photosystem II reaction center M protein PsbM; One of the components of the core complex of photosystem II (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. This subunit is found at the monomer-monomer interface.
  
 
 
 0.795
psb27
Photosystem II 11 kD protein; Plays a role in the repair and/or biogenesis of the calcium- manganese-oxide cluster on the lumenal face of the thylakoid membrane. Its presence in a photosystem II (PSII) preparation prevents binding of some small extrinsic subunits and thus assembly of calcium-manganese- oxide cluster.
  
   
 0.790
AFW96473.1
Hypothetical protein.
 
     0.787
psbY
Photosystem II protein PsbY; Manganese-binding polypeptide with L-arginine metabolizing enzyme activity. Component of the core of photosystem II. Belongs to the PsbY family.
  
 
 
 0.778
psbK
Photosystem II reaction center protein K PsbK; One of the components of the core complex of photosystem II (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation.
