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:
some 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

rhtAInvolved in the efflux of threonine and homoserine. Can also export other amino acids such as proline, serine, histidine and cysteine (295 aa)    
Predicted Functional Partners:
rhtC
Threonine efflux protein; Conducts the efflux of threonine
      
 0.900
rhtB
Homoserine, homoserine lactone and s-methyl-methionine efflux pump; Conducts the efflux of homoserine and homoserine lactone
   
  
 0.873
leuE
Leucine efflux protein; Exporter of leucine. Can also transport its natural analog L- alpha-amino-n-butyric acid and some other structurally unrelated amino acids
   
  
 0.863
ilvA
L-threonine dehydratase, biosynthetic; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA
  
  
 0.773
yddG
Aromatic amino acid exporter; Probable efflux pump. Overexpression confers resistance to phenylalanine and increases export of phenylalanine, tyrosine and tryptophan
  
   
 0.691
tdcC
L-threonine/l-serine transporter; Involved in the import of threonine and serine into the cell, with the concomitant import of a proton (symport system)
      
 0.590
sstT
Sodium:serine/threonine symporter; Involved in the import of serine and threonine into the cell, with the concomitant import of sodium (symport system)
      
 0.570
rhmD
L-rhamnonate dehydratase; Catalyzes the dehydration of L-rhamnonate to 2-keto-3-deoxy- L-rhamnonate (KDR). Can also dehydrate L-lyxonate, L-mannonate and D- gulonate, although less efficiently, but not 2-keto-4-hydroxyheptane- 1,7-dioate
      
 0.568
thrB
Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate. Is also able to phosphorylate the hydroxy group on gamma-carbon of L-homoserine analogs when the functional group at the alpha-position is a carboxyl, an ester, or even a hydroxymethyl group. Neither L-threonine nor L-serine are substrates of the enzyme
      
 0.567
thrA
Bifunctional aspartokinase / homoserine dehydrogenase 1; In the C-terminal section; belongs to the homoserine dehydrogenase family
      
 0.520
