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

yjbQPutative Na+/H+ antiporter; Probable Na(+)/H(+) antiporter; Belongs to the monovalent cation:proton antiporter 2 (CPA2) transporter (TC 2.A.37) family. (614 aa)    
Predicted Functional Partners:
thiE
Thiamine-phosphate pyrophosphorylase; Condenses 4-methyl-5-(beta-hydroxyethyl)thiazole monophosphate (THZ-P) and 2-methyl-4-amino-5-hydroxymethyl pyrimidine pyrophosphate (HMP-PP) to form thiamine monophosphate (TMP). Is also able to use the 2-methoxy analog MeO-HMP-PP, as substrate in vitro, but not the 2-trifluoromethyl analog CF(3)-HMP-PP. Belongs to the thiamine-phosphate synthase family.
  
 
 0.882
khtT
K+/H+ antiporter for K+ efflux; Required for activity of the potassium/proton antiporter KhtU. Involved in protection of the cell from methylglyoxal, a toxic by-product of glycolysis.
 
  
 0.807
ykuL
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 11985717.
  
  
 0.801
tenI
Thiazole tautomerase; Catalyzes the irreversible aromatization of 2-((2R,5Z)-2- carboxy-4-methylthiazol-5(2H)-ylidene)ethyl phosphate (cThz*-P) to 2- (2-carboxy-4-methylthiazol-5-yl)ethyl phosphate (cThz-P), a step in the biosynthesis of the thiazole phosphate moiety of thiamine. Cannot use cThz* as substrate, indicating that the phosphate group is essential. Has no thiamine phosphate synthase activity, despite a high sequence similarity with ThiE.
  
 
 0.766
thiG
Hydroxyethylthiazole phosphate synthetase (thiamine biosynthesis); Catalyzes the rearrangement of 1-deoxy-D-xylulose 5-phosphate (DXP) to produce the thiazole phosphate moiety of thiamine. Sulfur is provided by the thiocarboxylate moiety of the carrier protein ThiS. In vitro, sulfur can be provided by H(2)S.
  
  
 0.766
thiQ
N-formyl-4-amino-5-aminomethyl-2- methylpyrimidinedeformylase; Catalyzes the deformylation of the formylaminopyrimidine N- formyl-4-amino-5-aminomethyl-2-methylpyrimidine (FAMP) to give the corresponding aminopyrimidine; Belongs to the peptidase M20A family.
 
   
 0.756
ktrD
K+-transporting ATPase; Integral membrane subunit of the KtrCD potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress; Belongs to the TrkH potassium transport family. Ktr (TC 2.A.38.4) subfamily.
  
 
 0.751
ktrB
Potassium transporter ATPase; Integral membrane subunit of the KtrAB potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress.
  
 
 0.749
thiD
Hydroxymethylpyrimidine/phosphomethylpyrimidine kinase; Catalyzes the phosphorylation of hydroxymethylpyrimidine phosphate (HMP-P) to HMP-PP, and of HMP to HMP-P. Shows no activity with pyridoxal, pyridoxamine or pyridoxine.
  
  
 0.727
thiU
Thiamine binding protein; Part of the ABC transporter complex YkoCDEF that could transport hydroxymethylpyrimidine (HMP) and/or thiamine. Could also transport other HMP-containing products. Binds thiamine via its HMP moiety.
