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

dauAC4-dicarboxylic acid transporter; Responsible for the aerobic transport of succinate from the periplasm to the cytoplasm at acidic pH. Can transport other C4- dicarboxylic acids such as aspartate and fumarate. May also play a role in the regulation of C4-dicarboxylic acid metabolism at pH 7, via regulation of expression and/or activity of DctA. May act as a co- sensor of DcuS. (559 aa)    
Predicted Functional Partners:
cynT
Carbonic anhydrase; Reversible hydration of carbon dioxide. Carbon dioxide formed in the bicarbonate-dependent decomposition of cyanate by cyanase (CynS) diffuses out of the cell faster than it would be hydrated to bicarbonate, so the apparent function of this enzyme is to catalyze the hydration of carbon dioxide and thus prevent depletion of cellular bicarbonate.
 
  
 0.925
acpP
Acyl carrier protein (ACP); Carrier of the growing fatty acid chain in fatty acid biosynthesis; Belongs to the acyl carrier protein (ACP) family.
    
 
 0.906
can
Putative carbonic anhdrase; Belongs to the beta-class carbonic anhydrase family.
 
  
 0.888
yahD
Ankyrin repeat protein; Putative transcription factor.
    
 
 0.740
rimO
Ribosomal protein S12 methylthiotransferase; Catalyzes the methylthiolation of the residue Asp-89 of ribosomal protein S12.
  
    0.691
nuoM
NADH:ubiquinone oxidoreductase, membrane subunit M; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; Belongs to the complex I subunit 4 family.
  
 
 0.680
sbcD
Exonuclease, dsDNA, ATP-dependent; SbcCD cleaves DNA hairpin structures. These structures can inhibit DNA replication and are intermediates in certain DNA recombination reactions. The complex acts as a 3'->5' double strand exonuclease that can open hairpins. It also has a 5' single-strand endonuclease activity; Belongs to the SbcD family.
  
   0.670
dctA
C4-dicarboxylic acid, orotate and citrate transporter; Responsible for the aerobic transport of the dicarboxylates fumarate, L- and D-malate and to a lesser extent succinate, from the periplasm across the inner membrane; Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family.
   
  
 0.655
prs
Phosphoribosylpyrophosphate synthase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P).

ybjH
