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

kupKUP family low affinity potassium transport system; Responsible for the low-affinity transport of potassium into the cell, with the probable concomitant uptake of protons (symport system); Belongs to the HAK/KUP transporter (TC 2.A.72) family. (622 aa)    
Predicted Functional Partners:
kdpA
P-type ATPase, high-affinity potassium transport system, A chain; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit binds and transports the potassium across the cytoplasmic membrane.
   
  
 0.923
kdpC
P-type ATPase, high-affinity potassium transport system, C chain; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit acts as a catalytic chaperone that increases the ATP-binding affinity of the ATP-hydrolyzing subunit KdpB by the formation of a transient KdpB/KdpC/ATP ternary complex.
   
  
 0.860
kdpB
P-type ATPase, high-affinity potassium transport system, B chain; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit is responsible for energy coupling to the transport system. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IA subfamily.
      
 0.768
kdpD
Sensory kinase in two-component regulatory system wtih KdpE; Regulates kdp operon (high-affinity potassium transport system); similar to E. coli sensor for high-affinity potassium transport system (AAC73789.1); Blastp hit to AAC73789.1 (894 aa), 89% identity in aa 1 - 894.
     
 0.690
trkH
Trk family potassium transport protein; Low-affinity potassium transport system. Interacts with Trk system potassium uptake protein TrkA and requires TrkE for transport activity (By similarity); Belongs to the TrkH potassium transport family.
  
  
 0.661
rbsC
D-ribose high-affinity transport protein (1st module, ATP-binding subunit); ABC superfamily (membrane); similar to E. coli D-ribose high-affinity transport system (AAC76773.1); Blastp hit to AAC76773.1 (321 aa), 96% identity in aa 1 - 321; Belongs to the binding-protein-dependent transport system permease family.
     
 0.563
rbsA
D-ribose high-affinity transport protein; Part of the ABC transporter complex RbsABC involved in ribose import. Responsible for energy coupling to the transport system. Belongs to the ABC transporter superfamily. Ribose importer (TC 3.A.1.2.1) family.
  
    0.534
rbsD
D-ribose high-affinity transport system; Catalyzes the interconversion of beta-pyran and beta-furan forms of D-ribose.
       0.529
rbsB
D-ribose transport protein; Part of the ABC transporter complex RbsABC involved in ribose import. Binds ribose.
       0.522
yadQ
Putative ClC family chlorine transport protein; Proton-coupled chloride transporter. Functions as antiport system and exchanges two chloride ions for 1 proton. Probably acts as an electrical shunt for an outwardly-directed proton pump that is linked to amino acid decarboxylation, as part of the extreme acid resistance (XAR) response.
