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-transporting ATPase, A 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. (558 aa)    
Predicted Functional Partners:
kdpC
Potassium-transporting ATPase, C 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.

kdpB
Potassium-translocating P-type ATPase, B subunit, putative; 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.

kdpD
Sensor protein KdpD, putative; Member of the two-component regulatory system KdpD/KdpE that regulates the transcription of a series of virulence factors through sensing external K(+) concentrations. Regulates also capsular polysaccharide production. May function as a membrane-associated protein kinase that phosphorylates KdpE in response to environmental signals. In turn, KpdE functions as a transcriptional regulator by direct binding to promoter regions of target genes including spa, hla, aur and geh.

kdpE
DNA-binding response regulator, putative; Member of the two-component regulatory system KdpD/KdpE that regulates the transcription of a series of virulence factors through sensing external K(+) concentrations. Regulates also capsular polysaccharide synthesis. Upon phosphorylation by KpdD, functions as a transcriptional regulator by direct binding to promoter regions of target genes including spa, hla, aur and geh. Represses the transcription of kdpFABC operon.

cntC
Nickel ABC transporter, permease protein, putative; Part of the ABC transporter complex CntABCDF (Opp1) involved in the uptake of metal in complex with the metallophore staphylopine (StP). Involved in the import of divalent metals ions such as nickel, cobalt and zinc. Probably responsible for the translocation of the substrate across the membrane. Plays a major role in nickel/cobalt import in zinc-depleted conditions. Contributes to virulence. Required for full urease activity in vitro ; Belongs to the binding-protein-dependent transport system permease family.
