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

petEPlastocyanin; Participates in electron transfer between P700 and the cytochrome b6-f complex in photosystem I. (125 aa)    
Predicted Functional Partners:
petA
Apocytochrome f component of cytochrome b6/f complex; Component of the cytochrome b6-f complex, which mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions.
    
 
 0.895
petF
Ferredoxin (2Fe-2S); Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions.
   
 
 0.866
ABB57280.1
Photosystem I reaction center subunit III precursor; PSI-F; plastocyanin; cyt c553; docking protein.
   
 
 0.828
psaE
Photosystem I subunit IV psaE; Stabilizes the interaction between PsaC and the PSI core, assists the docking of the ferredoxin to PSI and interacts with ferredoxin-NADP oxidoreductase; Belongs to the PsaE family.
  
 
 0.759
cobS
Cobalamin-5'-phosphate synthase; Joins adenosylcobinamide-GDP and alpha-ribazole to generate adenosylcobalamin (Ado-cobalamin). Also synthesizes adenosylcobalamin 5'-phosphate from adenosylcobinamide-GDP and alpha-ribazole 5'- phosphate; Belongs to the CobS family.
      
 0.719
