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

AFY51165.1TIGRFAM: photosystem II protein PsbQ. (155 aa)    
Predicted Functional Partners:
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.
  
 
   0.945
psbT
Photosystem II reaction centre T protein; Seems to play a role in the dimerization of PSII. Belongs to the PsbT family.
  
 
   0.895
AFY49369.1
PFAM: Manganese-stabilising protein / photosystem II polypeptide.
    
 
 0.862
psbV
Cytochrome c-550; Low-potential cytochrome c that plays a role in the oxygen- evolving complex of photosystem II.
    
 
 0.858
psbC
Photosystem II reaction center protein P6/CP43; 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. PsbC subfamily.
    
   0.828
psbU
Photosystem II 12 kDa extrinsic 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.
  
 
 
 0.794
ycf12
Photosystem II complex subunit Ycf12; A core subunit of photosystem II (PSII); Belongs to the Ycf12 family.
  
 
   0.793
psbZ
Photosystem II core protein PsbZ; Controls the interaction of photosystem II (PSII) cores with the light-harvesting antenna; Belongs to the PsbZ family.
  
 
   0.773
AFY50053.1
PFAM: Ycf66 protein N-terminus.
  
     0.764
psbY
Photosystem II protein Y (PsbY); Manganese-binding polypeptide with L-arginine metabolizing enzyme activity. Component of the core of photosystem II. Belongs to the PsbY family.
