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

gltDGlutamate synthase, 4Fe-4S protein, small subunit; Catalyzes the conversion of L-glutamine and 2-oxoglutarate into two molecules of L-glutamate. (472 aa)    
Predicted Functional Partners:
gltB
Glutamate synthase, large subunit; Catalyzes the conversion of L-glutamine and 2-oxoglutarate into two molecules of L-glutamate.
 0.999
glnA
Glutamine synthetase; Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia.
  
 
 0.982
gdhA
Glutamate dehydrogenase, NADP-specific; Catalyzes the reversible oxidative deamination of glutamate to alpha-ketoglutarate and ammonia; Belongs to the Glu/Leu/Phe/Val dehydrogenases family.
  
 0.973
preA
Dihydropyrimidine dehydrogenase, NADH-dependent, subunit C; Involved in pyrimidine base degradation. Catalyzes physiologically the reduction of uracil to 5,6-dihydrouracil (DHU) by using NADH as a specific cosubstrate. It also catalyzes the reverse reaction and the reduction of thymine to 5,6-dihydrothymine (DHT).
  
 0.954
nuoF
NADH:ubiquinone oxidoreductase, chain F; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient.
 
  
 0.925
carB
Carbamoyl-phosphate synthase large subunit; Protein involved in arginine biosynthetic process and pyrimidine nucleotide biosynthetic process; Belongs to the CarB family.
  
 
 0.915
putA
Delta-1-pyrroline-5-carboxylate dehydrogenase; Oxidizes proline to glutamate for use as a carbon and nitrogen source and also function as a transcriptional repressor of the put operon; In the C-terminal section; belongs to the aldehyde dehydrogenase family.
     
 0.914
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine. Can also use NH(3) in place of glutamine.
  
 
 0.911
glmS
L-glutamine:D-fructose-6-phosphate aminotransferase; Catalyzes the first step in hexosamine metabolism, converting fructose-6P into glucosamine-6P using glutamine as a nitrogen source.
  
 
 0.911
fdhF
Formate dehydrogenase-H, selenopolypeptide subunit; Decomposes formic acid to hydrogen and carbon dioxide under anaerobic conditions in the absence of exogenous electron acceptors.
    
 0.911
