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

kdpAPotassium translocating ATPase, subunit A; 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. (557 aa)    
Predicted Functional Partners:
kdpC
Potassium translocating ATPase, subunit C; 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.
 0.999
kdpB
Potassium translocating ATPase, subunit B; 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.
 0.999
kdpF
Potassium ion accessory transporter subunit; 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 may be involved in stabilization of the complex.
   
 0.999
kdpD
Fused sensory histidine kinase in two-component regulatory system with KdpE: signal sensing protein; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon. KdpD may function as a membrane-associated protein kinase that phosphorylates KdpE in response to environmental signals.
 
  
 0.997
kdpE
Response regulator in two-component regulatory system with KdpD; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon.
  
 0.991
kup
Potassium transporter; Responsible for the low-affinity transport of potassium into the cell, with the probable concomitant uptake of protons (symport system). Can also transport cesium; Belongs to the HAK/KUP transporter (TC 2.A.72) family.
   
  
 0.921
malK
Maltose ABC transportor ATPase; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Maltooligosaccharide importer (TC 3.A.1.1.1) family.
     
 0.910
fhuB
Iron(3+)-hydroxamate import ABC transporter permease; Part of the ABC transporter complex FhuCDB involved in iron(3+)-hydroxamate import. Responsible for the translocation of the substrate across the membrane.
   
 
  0.904
fhuC
Iron(3+)-hydroxamate import ABC transporter ATPase; Part of the ABC transporter complex FhuCDB involved in iron(3+)-hydroxamate import. Responsible for energy coupling to the transport system.
     
  0.900
metQ
DL-methionine transporter subunit; This protein is a component of a D-methionine permease, a binding protein-dependent, ATP-driven transport system. Belongs to the NlpA lipoprotein family.
