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

all3953Probable RuBisCO transcriptional regulator; Trans-acting transcriptional regulator of RuBisCO genes (rbcL and rbcS) expression. (337 aa)    
Predicted Functional Partners:
hrcA
Heat-inducible transcriptional repressor; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
      
 0.766
psbV
Cytochrome c550; Low-potential cytochrome c that plays a role in the oxygen- evolving complex of photosystem II.
  
     0.719
ntcA
Nitrogen-responsive regulatory protein; Required for full expression of proteins subject to ammonium repression. Transcriptional activator of genes subject to nitrogen control.
  
  
 0.639
apcB
Allophycocyanin beta subunit; Light-harvesting photosynthetic bile pigment-protein from the phycobiliprotein complex. Allophycocyanin has a maximum absorption at approximately 650 to 653 nanometers.
  
     0.617
asr0043
ORF_ID:asr0043; hypothetical protein.
  
     0.614
psbU
Photosystem II 12 kD extrinsic protein; Stabilizes the structure of photosystem II oxygen-evolving complex (OEC), the ion environment of oxygen evolution and protects the OEC against heat-induced inactivation.
  
     0.590
asr3137
ORF_ID:asr3137; hypothetical protein.
  
     0.582
psbA
Photosystem II protein D1; Photosystem II (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. The D1/D2 (PsbA/PsbA) reaction center heterodimer binds P680, the primary electron donor of PSII as well as several subsequent electron acceptors.
  
   
 0.566
apcF
Phycobilisome core component; A variant beta-allophycocyanin (AP) which forms a complex with ApcE, a phycobilisome terminal emitter that influences energy transfer to photosystem II; Belongs to the phycobiliprotein family.
  
     0.564
cpcB
Phycocyanin beta chain; Light-harvesting photosynthetic bile pigment-protein from the phycobiliprotein complex.
  
     0.555
