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.

btpAPhotosystem I biogenesis protein. (282 aa)    
Predicted Functional Partners:
cce_1972
Protein involved in disulfide bond formation.
       0.682
psbB
Photosystem II CP47 protein, 47 kD chlorophyll-binding protein; 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.
      
 0.679
rimO
CHP1125-containing protein; Catalyzes the methylthiolation of an aspartic acid residue of ribosomal protein S12; Belongs to the methylthiotransferase family. RimO subfamily.
 
   
 0.660
chlN
Light-independent protochlorophyllide reductase, N subunit; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The NB-protein (ChlN-ChlB) is the catalytic component of the complex.
  
   
 0.600
psaK1
Photosystem I reaction center subunit X.
      
 0.566
nadB
L-aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.
      
 0.547
hemA
Transfer RNA-Gln reductase; Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA).
      
 0.545
apcE
Phycobilisome core-membrane linker polypeptide; Belongs to the phycobilisome linker protein family.
      
 0.543
psaJ
Photosystem I reaction center subunit IX; May help in the organization of the PsaE and PsaF subunits. Belongs to the PsaJ family.
      
 0.543
cce_1364
Putative 60 kD inner membrane insertion protein.
      
 0.543
