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.

citHSecondary transporter of divalent metal ions/citrate complexes; Transports the free citrate anion. Probably cotransports citrate and at least three or four protons. The citrate uptake is inhibited by the presence of magnesium ions; Belongs to the CitM (TC 2.A.11) transporter family. (426 aa)    
Predicted Functional Partners:
citS
Two-component sensor histidine kinase; Member of the two-component regulatory system CitT/CitS. Regulates the expression of the citM-yflN operon. Functions probably as a membrane-associated protein kinase that phosphorylates CitT in response to environmental citrate or Mg(2+)-citrate complex.
     
 0.807
yfnB
Putative hydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the HAD-like hydrolase superfamily. YjjG family.
      
 0.715
ywcA
Putative acetate Na+-dependent symporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
   
  
 0.618
cimH
citrate/malate/H+ symporter; Proton motive force-driven secondary transporter that catalyzes the uptake of both citrate and malate. Appears to be an electroneutral proton-solute symporter; the number of protons transported is equal to the valence of the transported anions. Is strictly stereoselective, translocating only the (S)-enantiomer of malate.
      
 0.569
crh
Catabolite repression HPr-like protein; Along with seryl-phosphorylated HPr, phosphorylated Crh is implicated in carbon catabolite repression (CCR) of levanase, inositol dehydrogenase, and beta-xylosidase. Exerts its effect on CCR by interacting with CcpA.
   
  
 0.524
citT
Two-component response regulator; Member of the two-component regulatory system CitT/CitS. Regulates the expression of the citM-yflN operon. Phosphorylated CitT binds to the citM promoter to activate the transcription of the citM- yflN operon.
     
 0.520
katE
Catalase 2; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide. Involved in sporulation.
       0.493
ccpA
Transcriptional regulator (Lacl family); Global transcriptional regulator of carbon catabolite repression (CCR) and carbon catabolite activation (CCA), which ensures optimal energy usage under diverse conditions. Interacts with either P- Ser-HPr or P-Ser-Crh, leading to the formation of a complex that binds to DNA at the catabolite-response elements (cre). Binding to DNA allows activation or repression of many different genes and operons.
      
 0.450
glnM
Glutamine ABC transporter (permease); Part of the ABC transporter complex GlnHMPQ involved in glutamine transport. Probably responsible for the translocation of the substrate across the membrane (By similarity); Belongs to the binding-protein-dependent transport system permease family.
   
    0.417
glnP
Glutamine ABC transporter (permease); Part of the ABC transporter complex GlnHMPQ involved in glutamine transport. Probably responsible for the translocation of the substrate across the membrane (By similarity); Belongs to the binding-protein-dependent transport system permease family.
