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

kdpCPotassium-transporting ATPase KdpC 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 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. (189 aa)    
Predicted Functional Partners:
kdpA
Potassium-transporting ATPase potassium-binding 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 binds and transports the potassium across the cytoplasmic membrane.
 0.999
kdpB
Potassium-transporting ATPase ATP-binding 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 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.
 
 0.999
kdpD
Probable sensor protein KdpD; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon. Functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of KdpE in response to environmental signals such as low levels of potassium ion, osmotic imbalance, acid and nutrient stresses. In turn, KdpE binds to the upstream promoter regions of target genes to positively regulate their expression.
 
  
 0.994
kdpF
Rv1028A, len: 30 aa. Probable kdpF, membrane protein, showing similarity with P36937|KDPF_ECOLI|B0698.1 protein KDPF from Escherichia coli strain K12 (see citation below) (27% identity); and KdpF protein from Streptomyces coelicolor (51% identity).
  
  
 0.917
kdpE
Probable transcriptional regulatory protein KdpE; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon. Upon phosphorylation by KdpD, functions as a transcription regulator by direct binding to promoter regions of target genes to positively regulate their expression.
 
  
 0.908
arfB
Possible membrane protein; Required for wild-type expression of ArfA and ammonia secretion, not however part of an ammonia transporter. Belongs to the ArfB membrane protein family.
   
  
 0.646
impA
Probable inositol-monophosphatase ImpA (imp); Catalyzes the dephosphorylation of inositol 1-phosphate (I-1- P) to yield free myo-inositol, a key metabolite in mycobacteria.
