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

isiBFlavodoxin; Low-potential electron donor to a number of redox enzymes. Belongs to the flavodoxin family. (174 aa)    
Predicted Functional Partners:
pcb
Light-harvesting complex protein; The antenna complex functions as a light receptor, it captures and delivers excitation energy to photosystem II and possibly to photosystem I. The Prochlorales pcb genes are not related to higher plant LHCs.
  
 
 0.693
psbC
Photosystem II PsbC protein (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.
   
  
 0.668
petF
Ferredoxin, petF-like protein; Alternative locus ID: PMED4_10091.
   
  
 0.651
PMM1172
Conserved hypothetical protein; Alternative locus ID: PMED4_13371.
       0.639
PMM1170
Conserved hypothetical protein; Alternative locus ID: PMED4_13351.
  
    0.610
psaE
Photosystem I PsaE protein (subunit IV); 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.
  
 
 0.575
petF-2
Ferredoxin; Alternative locus ID: PMED4_15201.
   
  
 0.571
PMM0370
Putative cyanate ABC transporter, substrate binding protein; Alternative locus ID: PMED4_04031.
  
   
 0.553
fur
Ferric uptake regulator family; Alternative locus ID: PMED4_06871; Belongs to the Fur family.
   
  
 0.533
PMM1173
Conserved hypothetical protein; Alternative locus ID: PMED4_13381.
       0.528
