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

yhaUTransporter involved in K+ efflux; Potassium/proton antiporter that mediates the efflux of potassium ions from the cell. Can also mediate rubidium/proton antiport, but has no permeability for sodium or lithium ions. In the absence of KhtT, does not have antiport activity, but can catalyze potassium efflux. Involved in protection of the cell from methylglyoxal, a toxic by-product of glycolysis, via activation by S-lactoyl-BSH of the antiporter activity, leading to cytoplasmic acidification and methylglyoxal resistance ; Belongs to the monovalent cation:proton antiporter 2 (CPA2) transpo [...] (405 aa)    
Predicted Functional Partners:
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.
 
  
 0.999
khtS
K+/H+ antiporter for K+ efflux; Modulates the activity of the potassium/proton antiporter KhtU. Involved in protection of the cell from methylglyoxal, a toxic by-product of glycolysis.

yrvC
Putative potassium transport accessory component; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative transporter.
 
    0.815
ydeA
Putative enzyme; 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 peptidase C56 family.
     
 0.709
yrpG
Putative oxidoreductase; 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 aldo/keto reductase family. Aldo/keto reductase 2 subfamily.
      
 0.680
mleN
malate-H+/Na+-lactate antiporter; Couples proton uptake and Na(+) efflux to the substrate- product malate/lactate antiport, in an electroneutral malate- 2H(+)/Na(+)-lactate exchange. Plays a role in supporting growth to high density on malate at reduced protonmotive force; Belongs to the NhaC Na(+)/H(+) (TC 2.A.35) antiporter family.
      
 0.611
yhdT
Putative membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
  
  
 0.553
yugS
Putative membrane protein involved in divalent ion export; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
  
  
 0.544
nhaC
Na+/H+ antiporter; Is a secondary, electrogenic Na(+)/H(+) antiporter that catalyzes Na(+) uptake and proton efflux. Makes modest contributions to pH homeostasis in the alkaline range of pH but is not contributor to Na(+) resistance. Appears to have a repressive effect on growth and on alkaline phosphatases production in the presence of sodium, by affecting the transcription of the phoP/phoR two-component regulatory system.
      
 0.523
yqkF
NADPH-dependent aldo-keto reductase; Evidence 2b: Function of strongly homologous gene; Product type e: enzyme; Belongs to the aldo/keto reductase family. Aldo/keto reductase 2 subfamily.
