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

brnQBranched-chain amino acid transport system 2 carrier protein; Component of the LIV-II transport system for branched-chain amino acids. This LIV-II transport system may be H(+)-coupled. (439 aa)    
Predicted Functional Partners:
proY
Proline-specific permease; Permease that is involved in the transport across the cytoplasmic membrane of proline; Belongs to the amino acid-polyamine-organocation (APC) superfamily. Amino acid transporter (AAT) (TC 2.A.3.1) family.
  
  
 0.813
sstT
Sodium:serine/threonine symporter; Involved in the import of serine and threonine into the cell, with the concomitant import of sodium (symport system).
 
  
 0.695
livJ
Branched-chain amino acid ABC transporter periplasmic binding protein; This protein is a component of the leucine, isoleucine, valine, (threonine) transport system, which is one of the two periplasmic binding protein-dependent transport systems of the high- affinity transport of the branched-chain amino acids; Belongs to the leucine-binding protein family.
  
   
 0.675
phoR
Sensory histidine kinase in two-component regulatory system with PhoB; Member of the two-component regulatory system PhoR/PhoB involved in the phosphate regulon genes expression. PhoR may function as a membrane-associated protein kinase that phosphorylates PhoB in response to environmental signals.
 
    0.654
cycA
D-alanine/D-serine/glycine transporter; Permease that is involved in the transport across the cytoplasmic membrane of D-alanine, D-serine and glycine; Belongs to the amino acid-polyamine-organocation (APC) superfamily. Amino acid transporter (AAT) (TC 2.A.3.1) family.
      
 0.565
gltP
Glutamate/aspartate:proton symporter; Catalyzes the proton-dependent, binding-protein-independent transport of glutamate and aspartate. Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family. GltP subfamily.
  
  
 0.525
yegW
Putative transcriptional regulator; Protein involved in transcription repressor activity and transcription.
     
 0.510
yaaJ
Putative transporter; Inner membrane transport protein.
  
  
 0.504
aroP
Aromatic amino acid transporter; Permease that is involved in the transport across the cytoplasmic membrane of the aromatic amino acids (phenylalanine, tyrosine, and tryptophan).
  
   
 0.496
ydjN
Putative transporter; Involved in L-cystine transport. Can probably also transport L-cysteine. Mediates accumulation of the toxic compounds L- selenaproline (SCA) and L-selenocystine (SeCys). Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family.
