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

natBNa+ ABC efflux transporter (permease); Part of an ABC transporter that catalyzes ATP-dependent electrogenic sodium extrusion. (386 aa)    
Predicted Functional Partners:
natA
Na+ ABC efflux transporter (ATP-binding protein); Part of an ABC transporter that catalyzes ATP-dependent electrogenic sodium extrusion; Belongs to the ABC transporter superfamily.

natR
Two-component response regulator [NatK]; Member of the two-component regulatory system NatK/NatR that positively regulates the expression of the natAB operon. Acts by binding directly to the promoter of natAB.
  
    0.579
natK
Two-component sensor histidine kinase [NatR]; Member of the two-component regulatory system NatK/NatR that positively regulates the expression of the natAB operon. Potentially phosphorylates NatR.
  
    0.540
yccK
Putative ion channel associated enzyme; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the aldo/keto reductase family. Aldo/keto reductase 2 subfamily.
