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

alaCGlutamate--pyruvate aminotransferase alac; Involved in the biosynthesis of alanine (412 aa)    
Predicted Functional Partners:
dadX
Alanine racemase, catabolic, plp-binding; Isomerizes L-alanine to D-alanine which is then oxidized to pyruvate by DadA
    
 0.929
alr
Alanine racemase, biosynthetic, plp-binding; Catalyzes the interconversion of L-alanine and D-alanine. Provides the D-alanine required for cell wall biosynthesis
    
 0.925
avtA
Valine--pyruvate aminotransferase; Involved in the biosynthesis of alanine
   
  
 0.874
metB
O-succinylhomoserine(thiol)-lyase/o-succinylhomoserine lyase; Catalyzes the formation of L-cystathionine from O-succinyl-L- homoserine (OSHS) and L-cysteine, via a gamma-replacement reaction. In the absence of thiol, catalyzes gamma-elimination to form 2- oxobutanoate, succinate and ammonia
      
 0.768
gltB
Glutamate synthase (nadph) large chain; Catalyzes the conversion of L-glutamine and 2-oxoglutarate into two molecules of L-glutamate
  
 
 0.750
pfo
Pyruvate-ferredoxin/flavodoxin oxidoreductase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin
  
  
 0.685
talB
Transaldolase is important for the balance of metabolites in the pentose-phosphate pathway
  
 
 0.650
ypdE
Broad-specificity exoaminopeptidase; Has a broad aminopeptidase activity on non-blocked peptides by progressively cleaving amino acids off the peptide substrate. Aminopeptidase activity stops at the residue before the first proline in the peptide. Cannot cleave when proline is the first N-terminal residue
    
   0.621
sgrR
Transcriptional dna-binding transcriptional activator of sgrs srna; Activates the small RNA gene sgrS under glucose-phosphate stress conditions as well as yfdZ. Represses its own transcription under both stress and non-stress conditions; this repression likely provides one measure of control over sgrR at the level of synthesis. Might act as a sensor of the intracellular accumulation of phosphoglucose by binding these molecules in its C-terminal solute- binding domain
      
 0.603
gcvP
Glycine decarboxylase, plp-dependent, subunit p of glycine cleavage complex; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein
