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

aldAlanine dehydrogenase; Catalyzes the reversible reductive amination of pyruvate to L-alanine. This enzyme is a key factor in the assimilation of L-alanine as an energy source through the tricarboxylic acid cycle. Belongs to the AlaDH/PNT family. (373 aa)    
Predicted Functional Partners:
alr
Alanine racemase; Catalyzes the interconversion of L-alanine and D-alanine. This organism is able to use both L- and D-alanine as a nitrogen source. May also prevent D-alanine from interfering with the use of L- alanine.
  
  
 0.996
agcS
Sodium:alanine symporter; Probably functions as a sodium/L- and D-alanine symporter for alanine uptake.
     
 0.833
hpt
Hypoxanthine (guanine) phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis. Belongs to the purine/pyrimidine phosphoribosyltransferase family. Archaeal HPRT subfamily.
  
  
 0.671
MMP1137
Lrp-Like Transcriptional regulatory proteins, AsnC family; Citation: Dahlke I, Thomm M. (2002) Nucleic Acids Res. 30:701-10.
     
 0.530
MMP0865
Adenosylmethionine---8-amino-7-oxononanoate aminotransferase; Citation: Kiyasu T, Nagahashi Y, Hoshino T. (2001) Gene 265:103-13; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
  
  
 0.523
nrpR
Transcriptional repressor of nif and glnA operons; Transcriptional repressor of nitrogen fixation and assimilation genes. Binds to two tandem operators in the glnA and nif promoters, thereby blocking transcription of the genes.
   
  
 0.515
upp
Uracil Phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate; Belongs to the UPRTase family.
      
 0.506
trxB
Thioredoxin reductase.
     
 0.488
glnA
Glutamine synthetase; Probably involved in nitrogen metabolism via ammonium assimilation. Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia.
  
  
 0.483
pyrG
CTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
     
 0.453
