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

focBPutative formate transporter; Involved in the bidirectional transport of formate. Belongs to the FNT transporter (TC 2.A.44) family. (282 aa)    
Predicted Functional Partners:
hyfR
Hydrogenase-4 transcriptional activator; A transcriptional activator of its own operon; when overexpressed operon expression is strongly enhanced by low pH (under pH 6.0), strongly inhibited by O(2) but only weakly stimulated by fumarate. Expression in situ is very weak.
  
  
 0.934
hyfA
Hydrogenase 4, 4Fe-4S subunit; Probable electron transfer protein for hydrogenase 4.
  
  
 0.846
hyfD
Hydrogenase 4, membrane subunit; Possible component of hydrogenase 4. Belongs to the complex I subunit 5 family.
  
  
 0.813
hyfF
Hydrogenase 4, membrane subunit; Possible component of hydrogenase 4. Belongs to the complex I subunit 5 family.
  
  
 0.785
hyfB
Hydrogenase 4, membrane subunit; Possible component of hydrogenase 4.
  
  
 0.774
hyfG
Hydrogenase 4, subunit; Possible component of hydrogenase 4.
  
  
 0.767
hyfJ
Putative processing element hydrogenase 4; Possible component of hydrogenase 4.
     
 0.758
hyfE
Hydrogenase 4, membrane subunit; Possible component of hydrogenase 4.
 
   
 0.740
fhlA
Formate hydrogenlyase transcriptional activator; Required for induction of expression of the formate dehydrogenase H and hydrogenase-3 structural genes. Also activates expression of hyf operon (encodes the silent hydrogenase-4 gene cluster).
      
 0.735
fdhF
Formate dehydrogenase-H, selenopolypeptide subunit; Decomposes formic acid to hydrogen and carbon dioxide under anaerobic conditions in the absence of exogenous electron acceptors.
  
  
 0.688
