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

Rru_A2196BFD-like (2Fe-2S)-binding region. (70 aa)    
Predicted Functional Partners:
Rru_A2195
Bacterioferritin; Iron-storage protein.
  
 
 0.891
Rru_A3474
Bacterioferritin; Belongs to the bacterioferritin family.
  
 
 0.804
Rru_A2294
Alpha amylase, catalytic region.
      
 0.675
nifW
Nitrogen fixation protein NifW; May protect the nitrogenase Fe-Mo protein from oxidative damage; Belongs to the NifW family.
     
 0.467
Rru_A1093
Hypothetical protein.
   
  
 0.464
Rru_A2153
TonB-like; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates. It could act to transduce energy from the cytoplasmic membrane to specific energy-requiring processes in the outer membrane, resulting in the release into the periplasm of ligands bound by these outer membrane proteins. Belongs to the TonB family.
   
  
 0.464
Rru_A3109
Aspartate racemase.
   
  
 0.449
Rru_A1092
Biopolymer transport protein ExbD/TolR.
   
  
 0.446
Rru_A2154
Biopolymer transport protein ExbD/TolR.
   
  
 0.446
Rru_A1933
uroporphyrinogen-III C-methyltransferase; Multifunctional enzyme that catalyzes the SAM-dependent methylations of uroporphyrinogen III at position C-2 and C-7 to form precorrin-2 via precorrin-1. Then it catalyzes the NAD-dependent ring dehydrogenation of precorrin-2 to yield sirohydrochlorin. Finally, it catalyzes the ferrochelation of sirohydrochlorin to yield siroheme.
