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

glnA[R] COG3968 Uncharacterized protein related to glutamine synthetase. (469 aa)    
Predicted Functional Partners:
gltB
Glutamate synthase, large subunit; [E] COG0070 Glutamate synthase domain 3.

KB13_1043
Glutamate-ammonia-ligase adenylyltransferase; Involved in the regulation of glutamine synthetase GlnA, a key enzyme in the process to assimilate ammonia. When cellular nitrogen levels are high, the C-terminal adenylyl transferase (AT) inactivates GlnA by covalent transfer of an adenylyl group from ATP to specific tyrosine residue of GlnA, thus reducing its activity. Conversely, when nitrogen levels are low, the N-terminal adenylyl removase (AR) activates GlnA by removing the adenylyl group by phosphorolysis, increasing its activity. The regulatory region of GlnE binds the signal transd [...]

KB13_410
Nitrogen regulation protein NtrB; [T] COG0642 Signal transduction histidine kinase.
 
  
 0.812
lpdA
[C] COG1249 Pyruvate/2-oxoglutarate dehydrogenase complex, dihydrolipoamide dehydrogenase (E3) component, and related enzymes.
  
 
 0.808
KB13_616
Transcriptional regulator, MerR family; [K] COG0789 Predicted transcriptional regulators.
  
 
 0.794
KB13_804
CDP-6-deoxy-L-threo-D-glycero-4-hexulose-3- dehydrase reductase; [C] COG0633 Ferredoxin.
   
 
 0.783
purL
Phosphoribosylformylglycinamidine synthase; Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
  
 
 0.777
trxB
Thioredoxin-disulfide reductase; [C] COG1249 Pyruvate/2-oxoglutarate dehydrogenase complex, dihydrolipoamide dehydrogenase (E3) component, and related enzymes.
    
 0.763
ntrC
Nitrogen regulation protein; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes.
  
  
 0.760
nadE
NAD+ synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
